# V2 Features — Fighting Game (Unreal Engine 5)

Status: V2 feature inventory  
Source: derived from `V2/V2_TODOS.md` (implementation backlog) and inspired by
the design footprint of Mortal Kombat, Street Fighter, Tekken, WWE 2K, EA Sports
UFC, Soul Calibur, and Def Jam: Fight for New York.  
Audience: design, engineering, audio, art, narrative, online services, and
publishing leads scoping V2.  
Date: 2026-05-12

> **This feature map has been decomposed into focused pages under
> [`features/`](./features/README.md).** This file remains the canonical hub —
> it preserves every section heading (so existing `features§"…"` and
> `V2_features.md#…` anchors keep resolving); the in-depth, code-grounded
> companion pages live under [`features/`](./features/README.md). Start at the
> [features page index](./features/README.md). The runtime/package architecture
> is in [`V2_ARCHITECTURE.md`](./V2_ARCHITECTURE.md) /

## Purpose

This document is the **feature map for V2**. It translates the V2 backlog into a
product-shaped scope document and describes what V2 ships across single-player,
multiplayer, online services, content authoring, accessibility, and live-service
surfaces. It does not replace the backlog checklist — `V2_TODOS.md` remains the
source of truth for completion state and agent execution order — but every
feature listed here is grounded in tasks explicitly laid out in `V2_TODOS.md`
plus the product behavior those tasks imply.

V2 is a single coherent fighting game whose experience spans the lineage of the
genre's most influential franchises:

- **Mortal Kombat** for finishers, Krypt, Towers of Time, and gore-as-spectacle.
- **Street Fighter** for motion-input depth, Drive/V-Trigger systems, World
  Tour, and Battle Hub presence.
- **Tekken** for 3D juggle culture, sidestep, customization, and side modes
  (Tekken Force, Devil Within).
- **WWE 2K** for sports-entertainment match types, Universe, MyCAREER, MyGM,
  MyFACTION, MyRISE, and Royal Rumble.
- **EA Sports UFC** for realistic MMA, stamina simulation, ground game, and GOAT
  Career.
- **Soul Calibur** for 8-way-run weapon combat, ring-out, Guard Impact,
  Chronicles of the Sword, and Create-a-Soul.
- **Def Jam: Fight for New York** for five-style street combat, Blazin' moves,
  environmental finishers, and hip-hop-driven crew storytelling.

V2's promise is not "blend everything every match" but **per-ruleset feel** —
when a match is in MK ruleset it must feel like MK; when it's in Tekken ruleset
it must feel like Tekken; when it's WWE it must feel like WWE — held together by
one shared roster, one shared creator suite, one shared online backbone, and a
unifying story.

## Subsystem Glossary

These are the core engine subsystems. `V2_ARCHITECTURE.md` carries the full
glossary — the same engine modules plus the racing modules, the game-feature
plugin roster, and repository surfaces. The entries below are byte-identical to
their counterparts there.

| Subsystem            | Responsibility                                                           |

## Cross-Reference Convention

Throughout this document, **bare `§N` and `§N.M` references resolve to
`V2_TODOS.md`** (the backlog has 138 numbered top-level sections and ~1000
numbered subsections; it is the only V2 doc with section numbering used as
hyperlinks). Explicit doc-prefixed references appear where ambiguity matters:

- `§80` → `V2_TODOS.md` §80 (Compliance Deep) — the default convention.
- `§52.8` → `V2_TODOS.md` §52.8 (Live-service operations cadence).
- `deps§57` → `V2_DEPENDENCIES.md` §57 (Hardware Peripheral SDKs).
- `arch§"<anchor>"` → `V2_ARCHITECTURE.md` by section anchor.
- `features§"<anchor>"` → this document, by section anchor.

`V2_features.md` and `V2_ARCHITECTURE.md` use named anchors, not numbers, to
avoid duplicating the TODOs numbering scheme.

## Repository Surfaces

This table maps V2's repository / package surfaces to their target paths;
`### Product Surfaces` in Part 1 covers the player-facing UX surfaces. Target
paths are created by the TODOs that first reference them.

## Part 1 — Foundations & Promise

Part 1 frames what V2 is: the product promise that holds seven fighting-game
lineages together and the player- and developer-facing surfaces V2 ships across.
The launch and exit criteria that gate release close out the document in Part 9.

### V2 Product Promise

V2 must ship as one product, not seven. The product should:

- Deliver per-ruleset feel that matches each inspirational source on its own
  terms — no compromise blends.
- Hold those rulesets together with one shared roster, one shared creator suite,
  one shared online backbone, and a unifying story.
- Make rollback netcode the default for **1v1 and 2v2 tag** modes, with
  frame-accurate determinism and ≤ 8 frames of rollback under typical conditions
  (≤ 100 ms RTT). Multi-fighter rollback runs at 60 Hz for 2v2 active fighters
  per side; 3v3 tag and Royal Rumble / ≥ 30 in-ring modes ship on client-server
  with rollback-emulated input prediction rather than full rollback. Modes
  outside the rollback envelope (Battle Royale 100-player, World Tour, Battle
  Hub, Convoy free-roam, Heist, World Boss) ship on client-server with dedicated
  servers.
- Ship complete launch content across every advertised mode — no "coming soon"
  panels.
- Provide first-class single-player content (Story, MyCAREER, MyRISE, Universe,
  MyGM, MyFACTION, GOAT Career, Tekken Force, Devil Within, Chronicles of the
  Sword, Def Jam Story, World Tour, Battle Hub) that each stand on their own as
  a ≥ 10 hour experience.
- Honor the audience: MK gore is opt-in/opt-out and locale-aware; UFC sim is
  faithful; WWE booking depth respects the genre; SC weapon depth is honored;
  Tekken juggle culture is preserved; SF motion inputs are unsmoothed; Def Jam
  soundtrack feel is preserved.
- Treat the creator suite — CAF (Create-a-Fighter), CAW (Create-a-Wrestler), CAS
  (Create-a-Soul), CAA (Create-an-Arena), CAE (Create-an-Entrance), CAM
  (Create-a-Moveset) — as a first-class product surface, not a checkbox.
- Deliver cross-play and cross-progression across PC, PS5, XSX, Switch2, Steam
  Deck.
- Degrade safely under offline, partial-net, weak-grounding, low-bandwidth,
  controller-loss, mid-match-disconnect, and provider-outage conditions.
- Launch only with automated verification, observability, runbooks, release
  gates, rollback plans, and post-deploy monitoring in place.

### Product Surfaces

#### Game Client

V2 game client includes:

- A persistent main menu front-end built on CommonUI, with Play, Modes Hub,
  Roster, Customize, Store, Settings, Extras, and a ticker showing online
  presence and matchmaking state.
- A Modes Hub funnel that surfaces every single-player and online mode in a
  taxonomy by ruleset (MK, SF, Tekken, WWE, UFC, SC, DJ) and by experience
  (single-player career, online competitive, social hub, creator suite).
- An in-match HUD that auto-switches per ruleset (Drive bars, stun meters, rage
  indicators, Hype/Blazin' segments, kickout meters, octagon stamina rings, Soul
  Charge gauges) and a HUD-scale + reduced-motion variant.
- A photo mode entry point reachable from any cutscene pause and any post-match
  screen.
- A replay viewer with editable camera and timeline, exportable to MP4.
- An in-game changelog feed and "what's new" surface.
- Hard parental controls for gore tier, profanity filter, online chat, community
  content visibility.

#### Marketing / Web Shell Tile (`apps/oshun/web/src/app/v2/`)

- V2 tile on `/explore` inside the shared Lilith/Oshun shell.
- `/v2` route that consumes `@oshun/shell-core`, `@oshun/auth-client`,
  `@oshun/developer-portal`, and `@oshun/persistence`.
- Roster, modes, news, patch notes, esports, and store content enter through
  shell-owned Oshun data surfaces rather than a standalone CMS stack.

#### Tournament Toolkit (`apps/v2/esports-tools/`)

- Bracket builder (single elim / double elim / round robin / Swiss / GSL).
- Match scheduler and result reporter.
- Broadcast overlay generator (lower thirds, brackets, score overlays).
- Anti-spoiler delay knob for finals.

#### Online Services Backend (`apps/v2/`)

- Auth (platform + cross-platform), friends, parties, presence.
- Matchmaking queues per mode (Casual / Ranked / Tournament / Crew / Royal
  Rumble lobby / UFC PPV public / Battle Hub instance).
- Leaderboards, replay cloud, ghost-data store, cosmetic store.
- Community content moderation pipeline.
- Telemetry ingest and balance dashboard feed.

## Part 2 — Combat & Game Feel

Part 2 covers the moment-to-moment fight: the layered combat systems, the
defensive vocabulary, the game-feel tuning that makes each ruleset hit like its
source, the per-ruleset feel definitions, and the tag-team and Kameo partner
systems that extend combat to two fighters per side.

### Core Combat Systems

V2 combat is layered. The layers below activate per ruleset.

#### Universal Layer

- Gameplay tag taxonomy covering stance, status, action, cancel, style, ruleset.
- Attribute set spine covering vitals (Health, Stun, Stamina, Drive, Heat, Hype,
  Resolve), movement (walk/dash/jump/sidestep), and combat (damage multipliers,
  throw-tech window, counter-hit multiplier, juggle scaling).
- Frame-data spine: every move carries startup / active / recovery / on-hit /
  on-block / cancel-window / hit-reaction-tag and is editable from one
  spreadsheet source of truth that drives runtime data tables.
- Hitbox / hurtbox engine with per-frame keyframe table on every notify segment,
  hit-priority resolution, same-attack hit-once registry, and trade resolution.
- Block / chip-damage / counter-hit / whiff-punish surface across all rulesets,
  with per-ruleset constants that change the feel.

#### Striking Layer

- 2D-style motion inputs (QCF/QCB/DP/RDP/HCF/HCB/360/720/charge), negative-edge,
  double-tap, plink, just-frame.
- Combo system with juggle scaling, wall splat, wall bounce, ground bounce,
  stage transitions, counter-hit state, whiff-punish window.
- Striking finishers (Critical Arts / Rage Arts / Critical Edge / X-Ray / Fatal
  Blow / Blazin') gated by per-ruleset meter rules.

#### Grapple Layer

- Universal command throws with input motion, throw-tech window, crouch tech,
  air throws, counter throws.
- Wrestling layer: clinch, tie-up rock-paper-scissors, grapple chain, body
  limb-damage map, pin / submission mini-games (configurable: mash / bar-stop /
  timing / breaking-point / grid), object usage (chair / ladder / table / kendo
  / sledgehammer / mic / belt), and the full WWE stipulation library (the
  canonical list is in the `### Per-Ruleset Feel` WWE Ruleset section).
- MMA layer: stamina simulation per limb, takedowns (shoot, body lock, trip,
  throw), sprawl defense, ground position state machine (full guard, half guard,
  side control, north-south, back mount, mount, crucifix, turtle, sprawl),
  ground-and-pound, submissions (rear-naked, guillotine, kimura, armbar,
  triangle, heel hook, americana, kneebar, anaconda, D'Arce, omoplata,
  gogoplata), cage interaction, doctor stoppage, 10-point must scoring, weight
  classes and rankings.

#### Weapon Layer

- 8-way run weapon combat with vertical / horizontal / kick / guard inputs,
  Guard Impact (repel / deflect / resist), Soul Charge, Critical Edge, ring-out
  and ring-out resistance, weapon disarm (cinematic-only).

#### Street Layer

- Five-style mix (Streetfighting / Wrestling / Martial Arts / Kickboxing /
  Submissions) with diminishing returns past two styles.
- Environmental finishers at stage hotspots (subway track, electric fence, fire
  pit, glass wall, barbed wire, brick wall, bar counter, dumpster, car hood,
  wood crate, chain-link fence, arcade machine).
- Blazin' meter (4 segments) and Blazin' moves driven by crowd hype and taunts.
- Crowd-as-participant with shove-back and rep gating.

#### Finisher Layer

- MK finisher window (Finish Him! prompt + 5s input window).
- Per-fighter Fatality 1, Fatality 2, Stage Fatality, ≥ 4 Brutalities,
  Friendship, Mercy, Babality.
- Gore-tier setting (Off / Mild / Standard / Extreme) with locale-aware
  defaults.
- X-Ray skeleton renderer (translucent skin + bone stencil overlay) with
  per-bone break states.

### Defensive Options Library

V2 collects the genre's defensive vocabulary into a per-ruleset toggleable
library so each match plays in the defensive grammar of the family it's
emulating:

- **Parry** (3rd Strike): block input on hit-frame; no chip; attacker stunned.
- **Just Defend / Just Block** (KOF / Garou): 0-chip block on perfect block
  frame.
- **Faultless Defense** (Guilty Gear): meter-cost air-and-ground guard with
  pushback / chip mitigation.
- **Instant Block** (Tekken): block input released and re-pressed on first
  contact for reduced blockstun.
- **Push Block / Advancing Guard** (MvC): directional + buttons while blocking
  pushes attacker away at meter cost.
- **Burst / Reversal** (Guilty Gear): one-shot defensive panic at burst-meter
  cost.
- **Counter Assault / Alpha Counter** (Marvel/Alpha): block + special → counter
  out of blockstring.
- **Guard Cancel** (KOF): cancel block into a roll / blowback at meter cost.
- **Hold / Strike / Throw Triangle** (DOA): RPS reversal layer used in WWE
  clinch and as a Soul Calibur "Reversal-Heavy" optional layer.
- **Negative Penalty** (KOF): inactivity penalty preventing turtling.
- **Reversal Edge** (SCVI): cinematic RPS clash at meter cost.
- **Drive Reversal** (SF6) and **Burnout** state.

Combo grammar: damage proration / starter scaling, tornado state, Roman / Fast
cancels (meter-cost cancel on any frame), kara cancels (1-2-frame normal-cancel
into special / throw extension), ukemi (forward / back / neutral ground techs
with i-frames), no-tech vortex setups, reset state warning, scaling reset on
wallsplat / stage transition / finisher.

Advanced movement: Korean Backdash Cancel, Wave Dash, Crouch Dash → iWS, 8-way
step cancel, Tiger Knee motion, dash-cancel registry per fighter.

Control schemes: Classic (full motion-input fidelity), Modern (assisted
single-button specials with 80% damage scaling, ranked-eligible), Dynamic
(fully-assisted, ranked-locked), Easy Fatalities / Easy Combos (accessibility /
casual; token-gated or non-ranked).

Attack property tagging: every move carries `AttackProperty` bits — Low / Mid /
High / Overhead / Crossup / Anti-Air / OTG / Unblockable — plus throw class
flag, punishable-on-block flag, hit-confirmable flag, side-swap flag. Editor
Validator blocks new moves without property data.

### Game Feel: Hitstop, Hitlag, Camera Shake

V2 centralizes game-feel mechanics into one tunable system so each ruleset hits
like the source it's emulating:

- **Hitstop / Hitlag / Sakkin**: per-move freeze frames on hit-confirm,
  counter-hit bonus, block hitstop, crush counter / punish counter emphasis
  frames, weapon clash sakkin on heavies. Curves authored per ruleset and per
  damage tier (MK aggressive, SF6 conservative, Tekken juice, SC moderate, UFC
  realistic, WWE broadcast).
- **Camera shake**: per-hit shake curve keyed on hit-reaction tag; per-ruleset
  intensity multiplier; per-fighter personality. Reduced-motion accessibility
  override.

  hold + zoom + tint, Reversal-Edge clash slow-mo, mid-combo emphasis freeze on
  heavy launchers.

  vignette, comeback aura, state-specific tints (Devil / Soul Charge / Heat /
  Blazin' / Burnout).

  editor utility widget, side-by-side replay harness for cross-ruleset
  comparison.

### Bonus Modes & Mini-Games

V2 honors the genre's tradition of bonus / non-canonical / silly modes. Each is
a short, self-contained loop with its own scoring and leaderboard; none are
ranked-eligible, and all are reachable as Battle Hub arcade cabinets.

  Tekken Force board breaker — fixed-timer destruction challenges scored on
  objects cleared.

  damage).

seasonal events; any bonus mode a player has not unlocked through play can be
made default-available as an accessibility accommodation rather than gated
behind grind.

### World Boss, Community Raid, Async Community Events

**World Boss.** A massive AI boss carries a single HP pool shared across the
entire community for a 7-day event window. The boss's shared HP is
**gameplay-inert during any individual match** — a player fights it in a normal
deterministic match, the match's frame-deterministic combat computes that
player's damage locally, and that damage is **submitted to the server after the
match ends**, never applied inside the rollback loop. Clients receive shared-HP
updates by server push for HUD display only. Per-contribution validation runs
the match's golden-replay hash through the cheat classifier before crediting the
account, so a tampered submission is rejected without affecting any live match.
Rewards tier on personal damage and on community completion (Bronze → Mythic),
with a per-event exclusive cosmetic for the top-1% of contributors; each boss
has a unique mechanic gimmick, a cinematic intro, and per-cycle state changes.

**Async Raid.** A 12-24 player raid runs across asynchronous per-player time
slots inside a 1-3 day window, so players in different time zones contribute to
the same raid; a quarterly signature raid ships a themed boss and a lore arc.

**Community challenges.** A weekly time-limited goal (e.g. "the community deals
1 billion damage to boss X within 7 days") grants a community-wide cosmetic on
completion; a per-region community split awards a per-region exclusive cosmetic.
Daily community goals grant a reward applied to every participant.

**Coordination and visibility.** A crew-coordinated world boss attempt puts 8-32
players in a shared instance with a co-op damage bonus. A server-tracked
community-aggregate dashboard shows total match count, Battle Pass progress,
tournament participations, and per-region state.

## Part 4 — Characters, Roster & Story

Part 4 covers the roster and the narrative around it: character presentation,
the launch roster and content inventory, the per-fighter signature library, side
stories and arcade endings, stages and their lore, the relationship matrix,
account progression and codex, and the director-commentary content layer.

### Character Presentation: Intros, Banter, Win Quotes

V2 honors the Injustice / MK11 standard of character-presentation depth:

- **Per-character pre-fight cinematic**: walk-in, pose, stance, voice-line.
- **Per-matchup pre-fight banter**: fighter A vs. fighter B trade 1-3 unique
  voice-lines specific to the matchup; mirror matches receive their own
  uniquely-authored mirror dialogue.
- **Per-stage intro variant** when applicable (WWE arena vs. MK pit vs. DJ
  club).
- **Round-specific intros** (final round, comeback round).
- **Mid-fight bark library** per fighter triggered by counter-hit, throw, parry,
  low-HP, combo-of-N, finisher armed / missed, with cooldown / priority rules.
- **Win / loss / draw quotes** (≥ 30 win, ≥ 15 loss, ≥ 5 draw per fighter),
  context-selected by opponent / ruleset / finisher used / perfect round /
  comeback / time-out / ring-out / pinfall / submission / KO / double-KO.
- **Per-matchup win quotes** when fighter A beats fighter B specifically.
- **Lore Page / character bio** per fighter with bio, style, signature moves,
  rival list, faction, concept art, alt-costume gallery — unlocks via match play
  / trials / missions / tower clears.
- **Entrance presentation** (deeper than intro): WWE-style ramp walk,
  Tekken-style stage-arrival, MK pit-summon, SF6 hub-arrival, DJ club-strut —
  with custom music slot.
- **Codec / between-round bites** (Tekken 7-style press conference snippets).
- **Post-fight victory cinematic** (pose hold with skippable photo capture), UFC
  presser, WWE mic moment.

### Roster & Content Inventory

#### Roster

- Launch roster ≥ 60 fighters covering archetype diversity, including original
  characters and partner-IP fighters (licensed individually).

  taunts.

#### Stages

- Launch stages ≥ 30 across all rulesets:
  - MK pits + hellish realms (≥ 5).
  - SF urban / international + dojo / cathedral (≥ 5).
  - Tekken stages with stage breaks and multi-floor (≥ 5).

#### Cosmetics

- Wardrobe library ≥ 500 items at launch; decals, masks, hair, jewelry, scars,
  dirt, accessories, weapon trinkets.

### Per-Fighter Signature Library

Every roster fighter carries a deep signature library:

- **Signature animations**: idle (8-12s unique loop), ≥ 3 taunts, intro pose,
  victory pose (3 variants), defeat / KO animation, knockdown / wake-up
  variation, slip / dodge / sidestep variation, air-recover, pursue, wake-up
  dust.
- **Signature audio**: per-fighter impact stings (≥ 8 unique), signature crowd
  chant, footstep variance keyed to footwear / armor, real-time vocal exertion
  layer driven by stamina, signature theme music with 3 dynamic variants.
- **Signature VFX**: low-HP / comeback aura, weapon glow / trail, finisher VFX
  kit.
- **Signature stage reactions**: cinematic close-up shader, throw-receiver
  react, hit-by-specific-move react (rival-specific recoil).
- **Authoring discipline**: per-fighter signature checklist at
  `V2/balance/fighters/<fighter>/signature-checklist.md`; QA cert pass verifies
  every roster fighter has every item. (Status 2026-06-12: checklists exist for
  all 60 launch-roster fighters, generated from the catalog with an explicit
  legend — a checked item attests the catalog-defined requirement; each
  checklist's "Asset authoring" section stays unchecked until real
  animation/audio/VFX assets exist, and the QA cert audit task remains open.)

## Part 6 — Online, Multiplayer & Esports

Part 6 covers everything networked: online services, network quality and private
rooms, cross-platform social and moderation, esports and tournament tooling,
streamer / speedrun / coach modes, the ranked season, the pro circuit, and local
and online co-op multiplayer.

### Online Services

V2's online backbone handles auth, social, matchmaking, ranked, replays, store,
and moderation behind one API gateway. Service-level targets are explicit:
matchmaking tickets resolve p50 ≤ 12 s and p99 ≤ 35 s at 5× expected launch
concurrency, auth p99 ≤ 200 ms, replay upload p99 ≤ 8 s for a 10-MB file, and
per-region availability ≥ 99.9%.

**Auth and social.** Platform and cross-platform auth, friends, presence,
parties (≤ 8), and invites run through the gateway; a session is a short-lived
JWT (15 min) plus a rotating 30-day refresh token.

**Matchmaking and ranked.** Per-mode queues (Casual, Ranked, Tournament, Crew,
Royal Rumble lobby, UFC PPV public, Battle Hub instance) use TrueSkill2 /
Glicko2 with region weighting, a ping cap that widens over wait time, and
role-preference balancing for tag and 4-player. Each mode has a seasonal ranked
ladder with placement matches and promotion / demotion thresholds; leaderboards
are global, regional, and friends-scoped.

**Replays, ghosts, reporting.** Cloud replay storage supports share-by-code, a
cloud library, and local download; ghost data is the replay encoded for Tekken
Ghost Battle and World Tour master training. In-game reporting feeds a
moderation review console with an appeal flow. Cross-play and cross-progression
bind to one publisher account root.

**Anti-cheat.** Four layers run together: EAC / BattlEye / platform-native
client drivers; server-side input-rate and attribute-integrity validation (input
bursts > 240/s flag, mismatched gameplay-effect application invalidates the
match); ML classifiers for smurf, win-trading, coordinated-throw, and
geographic-anomaly patterns; and a replay-based investigation pipeline. The
server re-simulates 1% of matches end-to-end and flags any frame drift. Severe
or repeat offenders take an HWID ban; every flagged match is forensically
logged. Classifier output prioritizes review queues but never issues automatic
discipline.

**Post-match and handshake.** The post-match screen offers Quick Rematch and
Rematch with Character Change; Player Match and Custom Room support first-to-N
set scoring. A pre-match handshake measures RTT, jitter, and packet loss, stamps
them into the match record, and warns on Wi-Fi or mobile-hotspot / 4G/5G
connections where the platform API exposes connection type; a per-account
network-reliability score feeds the ops dashboard.

### Network Quality, LAN, Server Browser, Private Rooms

**Netcode selection.** A 1v1 match begins with the pre-match handshake; if RTT,
jitter, and loss are good the match runs full rollback at 60 Hz with a ≤ 8-frame
rollback budget. Borderline conditions run a hybrid of rollback plus a small
input-delay buffer; RTT > 150 ms or sustained rollback pressure runs delay-based
netcode with an N-frame buffer. If a rollback match sustains rewinds > 8 frames
for ≥ 30 s, the client makes a one-time offer to switch to delay-based;
declining in ranked converts the match to a no-contest rather than forcing a
degraded fight.

**LAN tournament mode.** UDP-broadcast peer discovery runs with no internet
dependency, keeps a LAN-only ranking ledger separate from the online ladder, and
auto-enables when the client detects a registered tournament-venue Wi-Fi SSID.

**Dedicated server browser.** Primarily a PC surface (and console where TRC
permits), the browser lists public servers filterable by region, mode, ruleset,
latency, and player count. A host configures ruleset, stipulation, fighter
restriction, password, AFK-kick, and a rotating map list; server moderation
tools let the host manage the room.

**Custom Room / Private Lobbies.** Rooms support 1v1, 2v2, 4-corner, tournament,
Battle Royal, and Royal Rumble formats with ≤ 16 participants plus 8 spectators
and optional password gating. An in-room queue runs winners-stay-on,
losers-rotate-out, or randomized seating; per-room match settings are
host-controlled; spectators get an in-lobby training space so a waiting player
practices instead of idling.

### Cross-Platform Social, Reporting, Bans, Appeals

- **Cross-platform friends list** via publisher account; platform-native friends
  visible with icon; merge-duplicate prompt.
- **Cross-platform party** (≤ 8), voice + text chat persistent, party-up
  matchmaking, deep-link invites via Discord / platform DMs / share code.
- **Reporting categories**: Cheating, Harassment / hate speech, Sexual content,
  Threatening behavior, Custom-content abuse, Profanity / chat abuse, Trolling /
  griefing, Rage-quit / DC abuse, Impersonation, Spam. Auto-attach last 5-min
  replay + last 100 chat lines + screenshot.
- **Text + voice chat moderation**: per-locale profanity / hate-speech filter;
  voice via real-time STT → ML classifier; flagged voice quarantined for review;
  opt-out requires age verification.
- **Mute / block lists** synced cross-platform.
- **Ban tiers**: warning → 24h chat mute → 24h matchmaking ban → 7d → 30d →
  permanent; transparent escalation criteria.
- **Appeal flow**: in-game form + email, ops review within documented SLA,
  visible in account history.
- **Account integrity**: 2FA (TOTP + optional hardware key), recovery flow,
  lost-device handling, region-change cooldown (90d), account merge with
  consent + per-platform progression preservation.

### Esports & Tournament

**Tournament administration.** A TO badge account runs an admin tool that builds
single-elim, double-elim, round-robin, Swiss, or GSL brackets, assigns seeds,
schedules matches, drives broadcast, and auto-reports results; DQ, no-show
timeout, and round-extension override are TO controls. The TO uploads a
per-tournament rule file; the rule snapshot is stamped into every match's replay
header so the conditions a match was played under are auditable forever.

**Tournament Edition Settings.** A tournament locks the game to classic controls
only, default stages and costumes only, no Mercy / Friendship / Babality, a
forced side, and TO-set finisher on/off. Each event freezes to a specific patch
plus a Kustom Variation subset (cross-ref features§"Creator Suite"). Tournament
context also overrides rage-quit handling — any quit forfeits the match.

**Spectator and broadcast.** Spectator mode supports up to 8 in-match observers
(tournament mode raises the cap), TO-controlled anti-spoiler delay,
director-cam, picture-in-picture, side-by-side stick cam, drawing tools, freeze,
slow-mo, name plates, and a score overlay. A caster-facing broadcast HUD toggles
health bars, meters, frame counter, input display, character bios, headshots,
and lower thirds from a manual control surface. Output integrates with OBS / NDI
/ Spout, and a public broadcast SDK publishes a documented JSON websocket schema
for third-party overlay developers. Replay markers and clip-cut feed a
post-match recap reel.

**In-game tournaments.** Battle Hub Crown Tournaments run inside the client with
a public bracket, auto-progression, a side-stream per match, and a public
leaderboard, so a player enters a real bracket without external tooling.

**Result integrity.** Results are server-authoritative — V2 _pulls_ results from
Smash.gg / Start.gg / Challonge / Battlefy / Tournament.app and
cryptographically verifies each against the replay hash before it counts for
Crown Points; a client cannot push a fabricated result. A community tournament
toolkit gives player-run events the same auto-result reporting. An esports
portal on the marketing site aggregates schedules and standings.

### Streamer, Speedrun, Coach Modes

- **Streamer Mode**: hide handle + region, "Opponent" placeholder in HUD,
  disable voice chat default, suppress profile photo / status, blur lobby chat
  from non-friends, suppress capture-aware notifications.
- **Stream-Safe Music** automatically swaps licensed tracks for cleared
  analogues; per-track license-flag metadata; auto-on in Streamer Mode.
- **Coach Mode** in training (features§"Training, Trials, Tutorials"): friend
  joins as opponent or coach; coach can pause both clients, annotate frames, run
  dummy commands, push notes.
- **Async Coaching**: coach attaches annotations to a submitted replay; player
  is notified and watches annotated replay.
- **Speedrun Support**: built-in run timer for SP modes; per-mode split
  definitions; pace tracker against personal best; LiveSplit (PC) integration
  via local websocket; leaderboard ingest from speedrun.com partner program
  (read-only).

### Ranked Season Architecture

- **Season length**: 90 days; per-region overlap with global cup events.
- **Placement matches**: 10 at season start; MMR seed from prior season.
- **Off-season** 2-week tournament cycle with sandboxed MMR.
- **Season rewards**: cosmetics, faction XP, profile-card titles, exclusive
  emotes per top-rank tier.
- **Hidden MMR** (Glicko2 / TrueSkill2) drives matchmaking; never shown.
- **Visible Rank tiers**: Bronze / Silver / Gold / Platinum / Diamond / Master /
  Grandmaster / Legend.
- **Hysteresis** prevents rapid promotion / demotion oscillation.
- **Rank decay** above Master tier on 14-day inactivity.
- **Provisional rank** for new accounts (25 matches before public icon).
- **Retention bonus** for consistent weekly play.
- **Cross-platform unified MMR pool** with platform-icon-labeled leaderboard.
- **Crown / Pro Tour overlay**: tournament + ranked + invitational points;
  year-end Grand Final invite.
- **Sandbagging / throwing detection**; **match acceptance / decline rate**
  tracked; **coordinated-throw detection** for tournament play.

### Esports Pro Circuit, Broadcast Extras, Wildcard / Roulette

**Pro Circuit structure.** A per-region calendar (NA, EU, JP, KR, LATAM, SEA,
India, MENA) runs a qualifier → regional final → world final progression. Across
the year a cross-region series runs 4-6 majors plus monthly regionals; Crown
Points accumulate from every official and partnered event and gate world-final
qualification. Crown Points are formula-weighted by round, region, participant
count, and a season decay — a deeper finish at a larger event scores more — and
year-end totals invite the field to the Grand Final.

**Prize pools.** Each region's prize pool is funded from a cosmetic-sales pool
plus sponsor commitments, with the contribution percentage disclosed.

**Broadcast extras.** A spectator emote system (clap, gasp, boo, cheer, heart,
shock) bursts on-screen with caster-controlled visibility; a spectator hype
meter aggregates reaction velocity and drives both the broadcast overlay and
highlight-clip selection. Casters run polls through a Twitch Extension and an
in-broadcast cosmetic wager (no real money) for viewer participation. A
per-fighter caster cheat sheet auto-displays at character select.

**Wildcard / Roulette / Mystery.** Variant stipulations include random fighter
per round, spinning-wheel fighter selection, random ruleset switch, an
All-Fighter Tournament rule (each fighter usable once per set), and a Crew
Battle wildcard reveal mid-bracket. Each variant's results-eligibility is set by
the tournament rule file.

**Operations.** A searchable tournament archive indexes every event by event,
fighter, player, and year. The Esports Operations team runs a live-event on-call
schedule, the TO badge program, per-event LAN-play certification, and a
per-event integrity attestation.

### Split-Screen, Couch Co-op, Local Multiplayer, Hot-Seat

- **Split-screen 1v1**: vertical or horizontal split with per-side HUD +
  per-side controller config + 60fps target preserved.
- **Couch co-op** in Tekken Force / Devil Within / Konquest / Story: drop-in /
  drop-out + per-fighter pairing.
- **4-player local FFA** on shared screen or 4-way split.
- **Hot-seat mode** with per-account stat tracking even on shared controller.
- **Local-vs-LAN distinction** clarified per mode.
- **Local match XP attribution** to each account.
- **Per-side accessibility independence** (one side classic + one side assisted;
  per-side rumble independence for adaptive controllers).

### Co-op Online: Story / Tekken Force / Devil Within / Konquest / Crew Co-op

- **Story Co-op** (2 players): play through Story with a friend; per-chapter
  cinematics played for both; per-fight 2v2 or 2-vs-CPU-pair.
- **Tekken Force / Devil Within / Konquest Co-op online** with shared instance
  handoff + session host migration on disconnect + per-player loot share.
- **Crew Co-op online** (3v3 / 4v4): friend-stack vs another crew with team
  shared HP + per-crew lineup voting.
- **Co-op party matchmaking** (party of 2-4 queues together vs another party)
  with MMR-balanced + per-platform input-method labeling.
- **Async Ghost co-op**: load a friend's ghost as a co-op partner.
- **Co-op tutorials** explaining shared-objective semantics + per-player input
  ownership + drop-in/out rules.
- **Assist player carry**: stronger co-op player carries less-skilled;
  difficulty scales to stronger, credit goes to both.

## Part 7 — Live Service & Community

Part 7 covers the post-launch product: live service and DLC, the battle pass and
faction system, creator partnerships, the companion app and public API, the
seasonal calendar, community features and support, per-platform store and
region-aware pricing, AI commentary, brand partnerships, and the per-account
vault.

### Live Service & DLC

V2's post-launch content ships as `UGameFeaturePlugin` packages so a fighter,
stage, or mode can be installed, activated, hot-swapped, or removed without a
client patch. The Year-1 calendar runs on a fixed cadence: a monthly balance
patch (data-only hotfix where possible), a quarterly content drop (cosmetics +
one new tower season + one new Krypt area), and two paid DLC fighters per year
minimum, all authored by `@v2/maat-live-service-calendar` over `@maat/strategy`.

**Year-1 roadmap and editions**

- **Paid DLC**: 4 character packs (each: 1 fighter + 1 stage + ≥ 4 alt
  costumes + per-fighter signature library) and 1 mode-expansion DLC.
  License-conditional guest fighters ship one-per-plugin
  (`V2Mode_CelebrityGuest_<id>`) carrying per-skin rights metadata so a contract
  expiry removes exactly that plugin.
- **Free updates**: balance patches, new stages, new tower content, new
  tutorials, and accessibility improvements never sit behind a paywall.
- **Editions**: Standard; Deluxe (Standard + Year-1 DLC fighters + alt-costume
  bundle + premium currency grant); Ultimate (Deluxe + cosmetic packs +
  contracted early-access). Pre-order adds pre-load entitlement + cosmetic +
  announcer pack + emote pack with a transparent itemized list. Founders Edition
  is a limited physical run with art book, soundtrack, and optional statue.
- **Free Weekend / Demo**: limited roster (8 fighters) + 1 mode (Arcade);
  progress earned carries forward on full-game purchase.

**Plugin lifecycle and the no-coming-soon rule**

A DLC plugin moves through `authored → certified → staged → live → (sunset)`.
Staged plugins download in the background and unlock at the calendar date; a
sunset (license-expired) plugin is delisted from the store, its fighter is
disabled in matchmaking, and existing replays that reference it fall back to a
placeholder skin rather than failing to load. Every advertised mode ships
content-complete at launch — no "coming soon" panels (cross-ref features§"V2
Product Promise").

**Public Test Build and premium currency**

- **PTB** is an opt-in branch carrying balance patches 2 weeks before live;
  ranked is suspended on PTB and PTB MMR never writes to the live ladder.
- Premium currency (Krystals) is itemized with no surprise mechanics, no
  real-money loot boxes, and a configurable daily spend limit; `@maat/finance`
  owns spend, refund, region-aware pricing, and regulatory caps.

**Edge cases**: a patch that fails canary analysis triggers automatic hotfix
rollback to the prior signed manifest; a player who owns a sunset guest fighter
keeps purchased cosmetics in the vault but cannot select the fighter; offline
clients run the last cached hotfix values and reconcile on next sync.

### Battle Pass, Daily/Weekly Challenges, Faction System

**Battle Pass.** Each 90-day season runs a 60-tier pass with a Free Track and a
Premium Track. Tiers unlock via Pass XP earned from match play, daily challenge
completion, weekly missions, Story / tower progress, and faction quests; a
full-completion player clears 60 tiers in roughly 50-60 hours of varied play, so
the pass is finishable by a non-daily player inside the season. The Premium
Track grants only cosmetics, lore unlocks, and emotes — **no competitively
relevant item is ever paywalled** (cross-ref features§"V2 Product Promise"). A
tier-skip purchase is itemized in premium currency. Battle Pass progress is
cross-progression state (cross-ref features§"Online Services"); a season that
ends mid-match credits XP from that match before the rollover. Unclaimed
end-of-season rewards drop into the Reward Inbox rather than being forfeited.

**Daily and Weekly Challenges.** 3-5 daily challenges and a smaller weekly set
are issued from a server-driven manifest keyed per-fighter, per-mode, and
per-mechanic (e.g. "land 10 anti-airs", "win a round in MK ruleset"). The client
attaches the match's deterministic replay as evidence; the server validates
completion against the replay so a challenge cannot be spoofed (cross-ref
features§"Online Services" anti-cheat). Dailies rotate at 00:00 player-local;
weeklies rotate Monday. A challenge that becomes impossible (its fighter is a
sunset guest) is auto-swapped for an equivalent on next refresh. Daily Mission
rotation cross-links to the Battle Pass so one objective set feeds both.

**Seasonal Events.** Themed limited-time modes (Halloween Krypt Tower, Esports
Crown qualifier, Anniversary event) are scheduled by the live-service calendar
with a per-region override that auto-hides culturally inappropriate themes.

**Faction System (MKX-style).** A player picks one of five launch factions (Lin
Kuei, Black Dragon, Special Forces, Brotherhood of Shadow, White Lotus) at first
launch. Every match contributes faction XP to a faction-wide global leaderboard;
a weekly faction-vs-faction event ranks the five factions and grants the winning
faction's members an exclusive cosmetic. Factions unlock faction-exclusive
cosmetics, finishers, intros, banners, and lobby emotes. Switching faction
carries a 7-day cooldown and forfeits the current week's contribution, so the
weekly event cannot be gamed by hopping to the leading faction.

**Character Mastery** runs 1-30 levels per fighter, unlocking intros, victory
poses, color slots, and lore pages; Mastery 30 grants the signature finisher kit
(cross-ref features§"Fighter & Account Progression, Codex, Encyclopedia").

### Twitch Drops, Creator Partnership, Community Tools

**Twitch Drops.** During partnered events, watch-time on a participating channel
accrues a drop entitlement against the linked V2 account; the reward surfaces in
the profile's reward-claim flow and is granted as cosmetic-only items. Account
linking is a one-time OAuth step; an unlinked viewer is prompted before drops
accrue. Drops never grant gameplay-affecting items.

**Creator partnership.** A YouTube/Twitch creator-code system lets a player
attribute a store purchase to a creator (the code applies at store confirmation;
the attribution is transparent and changeable). Curated tutorial and combo
videos embed in-game, linked from the relevant fighter's move list and from the
settings tutorials panel, so a player stuck on a mechanic reaches a vetted video
without leaving the client.

**Community tooling.**

- **Discord rich-presence** publishes mode / ruleset / matchmaking state, and
  lobby invites deep-link back into the client.
- **In-app bug reporter** captures a screenshot, the session trace-id, and a
  reproduction-steps template, filing directly to the support backend; severe
  reports (crash, exploit) are auto-prioritized.
- **Canny-style feature voting** runs on the official forum backed by the
  feedback database; the community team triages on a published cadence and links
  shipped items back to the originating vote thread.
- **Roster Reveal Trailer pipeline** scripts in-engine MoviePipeline sequences
  for monthly DLC reveals, rendered from the same deterministic build the live
  game runs so the trailer cannot misrepresent the fighter.
- **Community tournament toolkit** lets players run brackets with auto-result
  reporting verified against replay hashes (cross-ref features§"Esports &
  Tournament").

### Companion App, Public API, Wiki, Roadmap

**Companion app.** A shell-native iOS / Android companion app delivers frame
data, codex queries, ban appeals, and second-screen and coach modes out of game.
**Second-screen mode** receives a low-bandwidth live stream of the opponent's
move list and frame data during a match; it is cosmetic-only and has no gameplay
effect. **Coach mode** lets a coach attach annotations to a submitted replay,
which the player then watches. Push handoff routes match-end, party-invite,
tournament-round, daily-challenge, and Battle-Pass-tier events to APNS / FCM
with per-category opt-out. The app is read-only out of game — it is not a play
surface and is excluded from cross-play.

**Public API.** A public REST API exposes player stats — rank, match history,
win rate, faction info, Crown Points — gated by a per-account public-flag, plus
webhooks for tournament organizers. Auth is OAuth 2.1 with PKCE; third-party
apps register through the developer portal for per-app scopes. Rate limits are
100 req/min for an unauthenticated app, 1000 req/min for a registered app, and
30 req/min per account on personal data, so a scraper cannot exhaust the
service.

**Knowledge surfaces.** An in-game wiki and glossary live at `/v2/wiki` and
`/v2/glossary`, backed by cited RAG answers covering frame data, per-ruleset
mechanic explanations, and strategy terms (hitstop, hitlag, kara cancel, OS,
shimmy, frame trap, parry, ukemi), with curated tutorial video embeds and a
downloadable cheat-sheet PDF. An in-game roadmap at `/v2/roadmap` tags each item
confirmed / planned / exploratory and delivers updates via an opt-in email
digest.

**Developer and modding.** A developer documentation portal publishes the API
reference, tournament-tool API, broadcast SDK, modding policy, code of conduct,
terms of service, and privacy policy, alongside an open-sourced Discord bot
template. The PC modding policy permits cosmetic mods offline and integrates
Steam Workshop for them, but gameplay-mod tampering is ranked-banned.

### Loading, Splash, Tips, What's New, Notifications

**First-boot sequence.** On a fresh install the client plays studio / publisher
/ engine logos, then rating-board acknowledgment screens, a photosensitivity
warning, and a health & safety warning where the region requires one. An age
confirmation gate runs per region law (cross-ref features§"Parental Controls,
Age Gating, Time-Played"), followed by a one-time personalization wizard that
sets language, controller, accessibility preset, and control scheme. The wizard
is re-openable from Settings; declining it falls back to platform-locale
defaults. After every patch, a "What's New" splash shows 3-5 headline changes
with screenshots or video, a link to full patch notes, and a roadmap teaser.

**Loading screens.** Per-mode loading screens rotate per-fighter portrait art
and a tip system of ~200 launch tips keyed per-ruleset, per-fighter, and
per-mechanic, each translated per locale. Match-load screens additionally host a
practice dummy (cross-ref features§"Training, Trials, Tutorials") that
auto-yields when the match is ready, so wait time is never dead time.

**Notification center.** A toast queue plus a persistent drawer surface friend
online, party invite, tournament round, daily challenge complete, replay shared,
faction quest, cosmetic shop restock, and patch-available events. Each category
is individually toggleable; toasts are rate-limited (1 per 2s) and overflow into
the drawer rather than stacking on screen. Streamer Mode auto-suppresses
capture-sensitive notifications while a capture session is detected.

**Help and onboarding.** Context-sensitive, controller-input-aware tooltips
attach to every UI element. First-time-played modes show skippable in-mode help
bubbles. Smart Help watches telemetry and surfaces a targeted help bubble — or a
tutorial-on-demand prompt — when a player repeatedly fails a specific mechanic.

**Cosmetics-only daily bonus and credits.** A 7-day rotating Daily Login Bonus
grants cosmetic-only rewards; the streak resets gracefully with no FOMO penalty
and no gameplay-affecting reward. The title screen rotates a roster spotlight
with seasonal music; menu music is themed per ruleset and mode. The end credits
roll lists every team member, mocap performer, VO cast member, composer,
partner, and licensor, and is searchable and browsable from the main menu.

### Live Service Calendar: Seasonal Themes, Anniversary, Charity, Console Tie-Ins

The live-service calendar is a single authored timeline (cross-ref
features§"Live Service & DLC") that schedules every dated event and exposes a
player-facing widget with a 6-month forward view and an opt-in email digest.

**Seasonal themes.** Monthly themes — Lunar New Year, Valentine's, IWD, Cherry
Blossom, Star Wars Day, Pride, Summer Festival, Anniversary, Halloween, Diwali,
Thanksgiving, Winter Holiday — each carry per-season cosmetics. A per-region
override auto-hides a theme that conflicts with local cultural or legal context
rather than shipping it everywhere; missing region data defaults to hiding the
theme.

**Anniversary.** Each Year-N anniversary ships a free content drop (1 free
fighter + 1 free stage + 1 free cosmetic bundle), throwback events, a livestream
with the next roadmap reveal, and commemorative profile flair for accounts
active during the window.

**Charity.** An annual charity event partners with one of AbleGamers, Special
Effect, Stack Up, EFF, ACLU, or an FGC charity prize-pool match. The donation
percentage is disclosed, an in-game progress meter tracks the running total, and
a charity stream collaboration anchors the event.

**Console tie-ins.** Tie-in plans for PS5 Pro, Switch 2, Xbox Series
new-revision, Steam Deck OS updates, and next-generation VR (PSVR3 / Quest 4 /
Vision Pro) are documented and scheduled against the calendar.

**Re-engagement.** A 60-day-inactivity trigger grants a returning-player reward
and sends a lapsed-player email; a Free Weekend runs every quarter.
Re-engagement messaging is bandwidth-throttled — at most one reactivation email
per lapsed player per 30 days, and the player can opt out per channel — so the
system never becomes spam.

**Reveals and community events.** DLC reveals run a 4-6 week reveal-to-launch
window. Player-voted bi-monthly events, creator-pitched events, and
community-led tournament series with cosmetic prize support feed the calendar. A
year-end retrospective publishes hours-played, pick rates, tournament
highlights, charity totals, and content-drop counts.

### Community Features: Player of the Week, Crew Showcase, Gallery, Newsletter

- **Editorial spotlights**: Player of the Week, Crew of the Month, and Replay of
  the Week are community-team picks; each spotlight grants the featured account
  a flair cosmetic and surfaces on the in-game News widget.
- **Community galleries**: an Art Gallery (player-created decals, arenas, CAWs,
  belts) and a Video Gallery (clips) present a curated, moderated subset with
  one weekly featured selection; every gallery entry links to the creator's
  profile. Submissions pass an ML pre-filter and a human review queue before
  they appear (cross-ref features§"Creator Suite" community gallery).
- **Devs-to-players channel**: an announcement channel capped at ≤ 3 posts per
  week; each post localizes to all launch locales within a 24-hour SLA.
- **Newsletter**: opt-in signup delivers a per-region monthly recap email and
  mirrors into the in-game News widget; unsubscribe is one click.
- **Player-meetup discovery**: an opt-in map surfaces per-region FGC events with
  a subscribable `.ics` calendar feed; location data is opt-in and never shown
  for accounts that have not enabled it.
- **Discord links** are per-region, each staffed by a per-region community team.
- **Public player journal**: a per-account markdown-supported journal, moderated
  on the same pipeline as gallery submissions; a player can keep it private or
  publish it to their profile.

### Per-Platform Store Features & Region-Aware Pricing (PPP)

V2's store is per-platform-store-native: each platform store keeps its own
consumable, entitlement, refund, and family-share semantics, surfaced through a
thin `IPlatformStore` adapter. The platform store is the **exclusive** path for
any item that grants gameplay state on that platform; non-item flows (coaching
marketplace, donations, esports prize pools, companion subscription) route
through Stripe / Adyen and are explicitly TRC-permitted.

**Per-platform integration.** Steam (achievements, trading cards, screenshots,
broadcasts, Workshop, controller config, Remote Play), Epic Games Store
(achievements, EOS mod.io), Microsoft Store (achievements, Game Pass option),
PSN (trophies, Share Play, party voice, PS Plus option), Xbox Live
(achievements, Smart Delivery, cloud save), and Switch 2 (My Nintendo, Friend
Share, save cloud) each integrate through their native SDK.

**Region-aware pricing (PPP).** Baseline price is multiplied by a per-region
purchasing-power ratio (regenerated quarterly from IMF + World Bank per-capita
data) and rounded to the nearest platform-allowed price tier. The per-region
price is ceilinged at baseline and floored at ratio × 0.4 to block inversion
attacks; the ratio refreshes quarterly only, so a player sees a stable price for
≥ 30 days. The client shows local-currency price plus the baseline equivalent
for transparency.

**VPN-region-shop detection.** Account region (set at first purchase, verified
at age-gate), session region (geo-IP), and payment region are compared; if more
than one disagrees for ≥ 90 days, a soft purchase block prompts the player to
either confirm a permanent region change (re-verify age, accept the new region's
content rules and rating) or cancel — V2 never silently applies a different
region's rules to the same account. Known business-traveller patterns are
whitelisted. Account region locks at first purchase with a 90-day cooldown.

**Sales, subscriptions, refunds.** Sale events align with each platform's
calendar (Steam Summer/Winter/Lunar/Spring, PSN Days of Play, Xbox seasonal,
Nintendo eShop). Game Pass / PS Plus catalog inclusion is a documented
negotiation option; a free-to-play conversion is roadmap-only for year 2+. Each
platform's refund policy and per-region statutory rights are honored;
per-account refund history is visible, and a refund-after-N-hours-played pattern
raises an anti-abuse flag.

### Customer Support, Community Ambassadors, Hall of Fame

**Customer support.** A support portal (in-game + web) opens tickets routed by a
priority-tier SLA: P0 (account compromise, payment dispute,
harassment-in-progress) gets first response ≤ 1 hour and resolution ≤ 24h; P1
(cheat report, ban appeal, payment failure) ≤ 8 hours / ≤ 72h; P2 (cosmetic
loss, friend-list bug, UI bug) ≤ 48 hours / ≤ 14 days; P3 (feature request,
general feedback) ≤ 7 days first response. Per-region hours, per-locale agents,
a knowledge base, and live chat (PC + web) back the portal. The feedback
database links bidirectionally with Canny-style feature voting.

**Community ambassadors.** A vetted ambassador program operates under a
transparent code of conduct with per-region rotation; ambassadors carry an
ambassador-only flair and receive early-access TO consultation. A separate
coaching-certification program issues a certified-coach flair, tracks a
per-coach rating, and supports paid coaching through platform-compliant payment
rails (cross-ref features§"Streamer, Speedrun, Coach Modes").

**Hall of Fame.** Tournament champions, all-time-record holders, and community
legends are inducted into a Hall of Fame rendered as an in-engine museum hub
with Krypt-style first-person navigation, inductee statues, trophy cases, and a
per-fighter wing. Induction is a server-recorded citation event. Pro-player
contracts for sponsored top players publish transparent qualification criteria,
and retired pros keep a pro-retired flair.

**Player input.** An in-game survey widget collects structured post-patch and
tournament-specific feedback; PTB beta enrollment is an opt-in toggle.

### AI-Generated Commentary, Highlight Reel, Per-Match Analysis

V2's AI features are all off-rollback: they read match telemetry and produce
audio, subtitle, text, or video output that never feeds simulation state. Every
shipping AI service carries an EU AI Act Model Card and an on-screen
machine-generated label.

**AI play-by-play commentary.** Real-time and post-match commentary is generated
from match telemetry with per-fighter and per-matchup narrative awareness; text
is synthesized to speech in the player's preferred announcer voice, per locale.
Real-time KO commentary targets ≤ 800 ms from the gameplay event to audio; on a
miss, the client falls back to a pre-recorded bank keyed by
`(cue, ruleset, commentator, seed)` so a slow generation never leaves dead air.
Commentary is opt-out in Settings.

**Auto-edited highlight reel.** After a match the system selects the top 3-5
moments (longest combo, counter-hit punish, Power-Play, dramatic comeback, KO)
and auto-edits them with cinematic camera and a music swell. Before sharing, the
player can trim, filter, swap music, and add a caption; export formats are MP4,
GIF, and vertical 9:16 for mobile. Reel generation targets ≤ 90 s for a 5-minute
match. Every export passes the NIL gate (cross-ref features§"Replay Theater,
Takeover, Spectator") — a reel containing an expired-rights fighter is saved
locally but blocked from online share.

**Per-match analysis.** An analysis screen breaks down damage by move, combo
structure, per-meter usage, and per-corner-pressure win rate, plus a
per-mistake-frame timeline with matchup-specific advice ("you missed 5 throw
techs in round 2"). A rolling per-fighter strength/weakness summary aggregates
recent matches.

**Auto-clipping and chat translation.** Best moments auto-clip into a
per-account clip library with an AI-suggested caption and title; the library
shares to friends or the public moderated clip gallery. Community chat supports
real-time per-message translation across locale boundaries with a manual
override.

**Post-launch procedural dialogue.** AI-generated per-fighter dialogue for DLC
seasons is always manually reviewed before deployment — generation accelerates
authoring but never ships unreviewed lines.

### Real-World Brand Partnerships, Celebrity Guests, Venue Tie-Ins

Every brand, celebrity, and venue partnership runs a contract lifecycle (term /
royalty / removal clause) and a partnership ethics review before it ships;
license-conditional content is isolated to one plugin so a contract end removes
exactly that content.

**Brand sponsorship.** Brands occupy authored slots in open-world signage,
vehicle decals, and racing sponsorship, allocated by a transparent brand-fit
score; a per-region brand-pool variant swaps brands per market. Launch partners
span Red Bull, Monster Energy, Nike, Adidas, Under Armour, and Logitech G. A
brand-themed Battle Pass season runs once per year with brand involvement
disclosed on the season screen.

**Celebrity guests.** A per-season celebrity guest — a real-world musician,
actor, or athlete — ships as a limited-time DLC fighter in its own
`V2Mode_CelebrityGuest_<id>` plugin, governed by a per-celebrity NIL contract
with a removal clause and a per-region content variant. Each guest carries a
unique signature library (intro, taunt, victory, lore), a themed fighter kit,
recorded VO, and a themed Battle Pass tier reward. On contract expiry the plugin
is delisted; owners keep purchased cosmetics in the vault but the fighter is
disabled in matchmaking, and replays fall back to a placeholder skin.

**Venue tie-ins.** Real-world iconic venues — Madison Square Garden, T-Mobile
Arena, Tokyo Dome, Suzuka Circuit — license as in-game stages with venue-flavor
commentary; each ships per-venue under a licensing-conditional manifest with a
removal clause and per-region availability.

**Physical and event tie-ins.** Pop-up V2 events at conventions (E3, Gamescom,
Tokyo Game Show, PAX, EVO) issue an in-game tie-in (promo code, cosmetic, or
commemorative flair); per-event physical merchandise syncs with an in-game
cosmetic. A per-quarter brand-sponsored limited-time mode (Red Bull Aerial
Stunt, Monster Energy Drift Cup) ships brand cosmetics plus a leaderboard.

**Ethics gate.** A community-advisory board with sensitivity readers and
cultural reviewers signs off every partnership; a partnership that violates
community standards is rejected regardless of commercial value.

### Per-Account Vault, Lifetime Replay Archive, Ghost Data Archive

The vault is the player's permanent cloud-side collection. It holds every owned
cosmetic (skins, weapons, banners, titles, emotes, vehicles, custom designs)
with no slot cap, organized by folders, classified by tags, and searchable with
a query language; a per-tier display upgrade unlocks through Account Level. The
vault is cross-progression state — it survives platform switches and account
merges.

**Lifetime replay archive.** Every match replay is preserved cloud-side and
searchable by mode, fighter, opponent, date, outcome, and rank. A favorited /
pinned subset stays at the top; the player can export any replay to a local file
or to MP4 within the per-replay export budget. Replays referencing a sunset
guest fighter still load with a placeholder skin (cross-ref features§"Real-World
Brand Partnerships, Celebrity Guests, Venue Tie-Ins").

**Lifetime ghost-data archive.** Every Time Trial, Canyon Duel, and
training-mode lab-session ghost is preserved, shareable as a code, and loadable
as an opponent in any ghost-supporting mode.

**Lifetime stats.** Per-fighter win rate, per-stage win rate, per-matchup
history, per-rank history across all seasons, and career-spanning achievement
tracking are preserved permanently.

**Sharing, backup, transfer, inheritance.**

- A friend can browse your vault cosmetically (no editing); per-vault privacy
  controls gate visibility.
- A daily snapshot writes to immutable cold storage; an accidental deletion is
  recoverable via restore-from-backup.
- On a cross-platform account merge, vault items are de-duplicated, transferred,
  and written to an audit trail (cross-ref features§"Cross-Platform Social,
  Reporting, Bans, Appeals").
- An optional estate-planning inheritance lets a player designate a beneficiary
  to receive vault contents on documented passing; the transfer requires
  verified identity, beneficiary readiness, accepted delegation evidence, and an
  immutable transfer audit record.

## Part 8 — Racing Component

Part 8 covers the full AAA racing component V2 ships as a peer genre to the
fighting game: the vehicle framework, career and race modes, the vehicle roster
and racing online, the racing × fighting crossover, vehicle and pit-crew
authoring, free-roam and heist modes, demolition derby, sports-vehicle modes,
and the persistent open world.

### Racing Component: Overview & Integration

V2 ships a full AAA racing component as a peer genre to the fighting game,
drawing on the lineage of the genre's most influential franchises:

- **Need for Speed: Most Wanted** for Blacklist career progression and police
  pursuit.
- **Split/Second** for Power-Play environmental hazards.
- **Blur** for pickup combat racing.
- **Death Race** for weaponized vehicles.
- **GRID** for sim handling and flashback rewind.
- **Need for Speed: Carbon** for canyon duels, crew progression, and drift
  scoring.
- **Need for Speed: Underground 2** for deep vehicle customization and
  open-world exploration.
- **Need for Speed: Hot Pursuit** for the cops-vs-racers asymmetric mode.
- **WipEout / F-Zero / Star Wars Episode I** for off-road / rally, motorcycles,
  and futuristic anti-grav pod-racers — additional vehicle classes beyond the
  street-racing core.

V2 racing and V2 fighting share one roster, one online backbone, one cosmetic
shop, one Battle Pass, and one profile + match history + currency ledger.
Crossover modes feature fighter-as-driver, vehicle-on-vehicle melee, and
get-out-and-fight transitions.

**Determinism boundary.** Racing does **not** run on the fighting game's
rollback netcode. Continuous-physics solvers (hovercraft, bike-lean, drift) are
not bit-identical across CPU vendors under cross-platform float modes, so racing
ships on client-server with input prediction: the Chaos vehicle solver runs
server-authoritative, the server replicates pose to every client, and
client-side prediction smooths only the local pose and never resimulates
physics. The fighting game's "bit-identical" promise is replaced for racing by
"server-consistent outcomes across all clients within one frame of replication
latency." Cheat detection therefore runs server-side on the authoritative state.

Launch scope:

- **Vehicle roster ≥ 70 vehicles** across cars / bikes / off-road / futuristic /
  specialty / police.
- **Tracks ≥ 40** across circuit / sprint / drift / drag / off-road / rally /
  canyon / sky / desert / city / futuristic.
- **Racing-side career arc** with ≥ 30 hours of single-player content including
  Most Wanted-style Blacklist progression, Carbon-style territory wars + canyon
  duels, NFSU2-style hidden parts hunt.

### Vehicle Framework, Physics, Tracks, Customization

  Eliminator, Time Trial, Knockout, Pursuit / Patrol, Open-world cruise.
- **Open-world Metro City** with ≥ 8 distinct districts (downtown neon NFSU2
  vibe / sun-baked desert Hot Pursuit / canyon cliffs Carbon / rainy port Most
  Wanted / harbor-bridge NFSU2 / industrial / suburb / airport).
- **Per-track racing line** authored + AI-line override; per-track sector
  splits + leaderboards + hazards + photo-mode hot-spots + spectator-cam
  positions.
- **Vehicle Customization (NFSU2 depth)**: body kit slots, autosculpt geometry
  deformation, paint system with multi-tone schemes + 8 finish types, vinyl /
  decal painter with layered blend modes + projection mapping, wheel
  customization (≥ 200 rim designs at launch), neon / underbody glow, window
  tint, exhaust tip, license plate, hydraulics, sound system, hidden parts hunt
  in open world, test drive before purchase.
- **Performance tuning**: engine swap, ECU tune, turbo / supercharger, NOS
  capacity + injection rate, transmission gear ratios, suspension tune, brake
  upgrade, drivetrain conversion (limited), weight reduction.

### Racing Career Mode (Most Wanted + Carbon + NFSU2)

- **Single-player career arc** (≥ 30 hours): climb a Most Wanted-style Blacklist
  of 15 named rivals + Carbon-style crew progression + NFSU2- style open-world
  exploration.
- **Per-rival event** (signature: sprint / circuit / drift / drag / canyon duel
  / pursuit); win unlocks rival's signature vehicle + customization parts +
  story chapter.
- **Per-rival cinematic** (pre-race trash-talk + post-race defeat).
- **Territory war** (Carbon-style): claim a territory by winning its signature
  race + defending from rival-crew challenges; per-territory perks + bonus
  currency.
- **Heat system** (Most Wanted-style police escalation): Heat 1-6 with per-level
  cop loadout (patrol → sergeant → federal → corvette → SWAT / rhino-truck →
  helicopter siege); cooldown via safehouse / paint change.
- **Reputation system**: per-event style points (drift / takedown / drafting /
  cop-evasion) feed reputation tier.
- **Final Blacklist boss event**: cinematic canyon-duel finale + career-ending
  cinematic.

### Race Mode Variants, Police Pursuit, Combat Racing, Power-Play

- **Race mode variants**: Circuit Race + Sprint + Drag (perfect-launch /
  perfect-shift bonuses) + Drift (angle × line × speed × duration ×

  signature vehicle unlocked via Mastery + Side Story; per-fighter driving
  personality affects AI behavior; per-fighter pre-race banter + per-matchup
  driving-context lines.
- **Get-Out-and-Fight mode**: in crossover events, vehicle KO (totaled) triggers
  cinematic where driver exits + engages in melee combat against opponent in
  chosen ruleset (MK / SF / Tekken / WWE / UFC / SC / DJ); per-race-stage
  fighting arena (track stretches / off-track areas) with environmental
  finishers eligible; winner returns to vehicle / claims opponent's vehicle;

### Racing Compliance, Trophies, Anti-Cheat, Accessibility

**Licensing.** Every licensed vehicle carries a per-manufacturer contract with
term, royalty, removal clause, and a damage-portrayal clause. Damage-tier
permissibility is per-manufacturer: a licensed luxury brand may permit only
cosmetic damage, so its vehicles never visibly deform past the Scuffed tier,
while original-IP vehicles run the full 5-tier model through to Totaled.

**Content rules.** Per-region racing variants adjust cop visuals for the China
publisher SKU, restrict combat-racing weaponry where required, switch the
speed-limit display between km/h and mph, and localize number-plate format. V2
depicts no drunk or impaired driving anywhere, and outside the Death Race
ruleset cops are "incapacitated", never killed.

**Trophies and anti-cheat.** A per-platform racing trophy/achievement plan
covers per-mode, per-vehicle-class, per-rank-tier, and special-condition
unlocks. Racing anti-cheat layers per-section physics-impossible-time detection
(a sector time below the physically achievable minimum flags), the
replay-determinism gate, and tuning-cheat detection against the trusted hotfix
bounds.

**Peripherals.** Wheels from Logitech, Thrustmaster, Fanatec, Hori, and MOZA are
supported with per-vehicle force-feedback tuning (cross-ref features§"Hardware
Peripherals Deep").

**Accessibility.** The full assist library is toggleable; an auto-throttle mode
serves motor-impaired players; difficulty steps down after consecutive losses;
and a reduced-motion racing camera clamps motion blur and camera shake.

### Vehicle Designer & Pit Crew Minigame

**Custom Vehicle Designer.** Players design vehicles from scratch: autosculpt
geometry shaping, a custom engine bay, transmission tunnel, and suspension, plus
engine-layout authoring (cylinder count, arrangement, turbo), and custom paint,
decal, vinyl, and wheel designs. A per-component balance budget caps the build —
engine, aero, tires, and weight reduction each carry a cost ceiling and the
designer rejects a build whose total exceeds the budget — so a custom vehicle
cannot out-stat the curated roster. Each design saves to a per-vehicle slot and
exports a shareable Base32 code carrying an account watermark and creation
nonce; codes never expire but are revocable per-account on moderation. A design
is ranked-eligible only after it clears originality review (verified against the
IP/brand database) and a manual approval pass; until then it is offline-only.

**Pit Crew Mechanic Minigame.** A timed repair/tune loop runs per-action
mini-games — tire change, oil change, engine swap, wheel alignment, suspension
tune — with a per-crew-member specialty bonus. It integrates with sim-mode
racing as pit-stop strategy and supports Coach-Mode-style co-op pitting where a
second player runs the pit while the first drives.

**Telemetry and showcase.** A per-driver telemetry dashboard records average lap
time, best-of-3, fastest sector, fuel, and brake-wear per race, and surfaces a
per-driver style classification into matchmaking. Every track supports reverse
and mirror variants. A Vehicle Showcase mode frames a vehicle with cinematic
camera and auto-pose presets and exports to MP4.

### Convoy & Free-Roam Multiplayer Lobby

The free-roam lobby places 8-32 players into open-world Metro City to cruise
freely on a client-server instance. Instances shard per region with
friend-priority sharding so a party lands together, and each instance runs a
synchronized day/night cycle and weather state shared across every player in it.

- **Convoy formation** lets 2-8 players lock into a shared waypoint with
  automated formation driving; an active convoy grants a crew cosmetic bonus,
  and NPCs initiate convoy challenges.
- **Player-meet hot-spots** per district (parking lots, under-bridge hangouts, a
  scenic overlook, the harbor pier, a drift-practice lot) give cruisers a place
  to gather.
- **Cruise photo session** captures a cooperative multi-player pose.
- **Social affordances**: open-world text chat, a proximity-limited voice radio,
  a cosmetic horn, and a flash-headlight gesture that initiates a challenge.
- **Co-op cruise objectives** (escort cargo, outrun a rival convoy, tag-team
  Power-Play training) give the lobby light shared goals.

Cruise mode has **no ranked progression** — it grants cosmetic and XP rewards
only — so the social space stays low-pressure.

### Heist Mode: Stealth, Driving, Fighting

**Structure.** Heist Mode is a multi-stage co-op mission for 1-4 players that
chains stealth, driving, and fighting in one run. The stage machine is
`Recon (stealth + observation) → Approach (drive + evade) → Infiltration (stealth or breach + fight) → Extraction (drive away + police pursuit + crew defense + Power-Play opportunities) → Resolution (cinematic outcome)`.
Each stage has an explicit fail-state and a retry budget; ≥ 3 failures in a
stage branches the run into an alternate outcome rather than ending it.

**Roles and AI.** Each crew member fills a role — Hacker (stealth + hacking
minigame), Wheelman (driver), Muscle (fighter), Strategist (planning + assists)
— with a per-role mini-game per stage. Stealth AI guards run a
`Patrol → Suspicious → Searching → Alerted → Combat → Lost-Sight → Patrol` state
machine; difficulty scales guard count and perception radius.

**Stealth-vs-fight payoff.** A stealth bypass grants a 1.5× loot multiplier; a
full-combat clear grants 1.0× plus bonus combat XP; mixed outcomes scale
linearly between the two — so a clean run pays more but a loud run is still
viable. A heist payout grants large currency, rare cosmetics, signature vehicle
unlocks, and a faction-influence boost; a failed heist still pays a partial
amount but spikes the heat level and costs crew loyalty.

**Co-op and access.** Each heist has 3 fixed branch decision points. Online
4-player co-op assigns roles, migrates the session host on disconnect, and
splits loot equally by default with an optional Robin-Hood modifier (the top
contributor may voluntarily share more); a rage-quit forfeits that player's
share. A solo heist fills empty roles with AI crew at 75% rewards. A per-quarter
signature heist (Casino, Bank Vault, Yacht, Train Robbery, Stadium Concert)
ships as a themed limited-time event with a cinematic narrative arc.

### Demolition Derby, Vehicle-Hijack, Fight-On-Vehicle

- **Demolition Derby**: arena mode 4-16 vehicles fight in enclosed bowl until
  one remains; per-vehicle HP + collision damage + melee weapons; per-arena type
  (classic bowl / figure-8 / industrial yard / stadium / parking-garage
  multi-level); 2v2 / 4v4 team derby option.
- **Vehicle-Hijack** mid-race: in Combat Racing crossover, attempt to hijack
  opponent's vehicle when alongside; input-RPS for control; success = attacker
  takes opponent's vehicle and position.
- **Fight-On-Vehicle**: cinematic fighting on a moving vehicle (Tekken
  Heihachi-on-motorcycle inspired). Per-vehicle Fight-On-Vehicle compatibility
  (convertibles / trucks / bikes / pod racers) with per-vehicle fight-stage
  authored. Per-vehicle environmental finisher (toss into traffic / ram into
  pillar / throw into chasm).
- **Mad-Max-style truck/bike chase combat**: one player drives heavy truck
  pursuing 1-3 bike-rider opponents; bike-riders attack truck (climb-aboard
  finisher / lasso pillar); truck rams bikes off road.
- **Convoy Raid co-op**: 2-4 player attacker crew vs AI convoy defending
  valuable cargo with per-cargo type variety.
- **Crossover ranked queues** with separate MMR per crossover queue.

### Sports Vehicle Modes: Soccer / Stunt / Crash / Trackmania

- **Vehicle Soccer** (Rocket-League-inspired): 3v3 / 4v4 cars vs ball with
  arcade physics (high-spin / boost-jump / aerial play); per-arena variant
  (rectangle / dome / multi-tier / hoops / volleyball pitch); ranked Soccer
  queue; per-fighter signature Soccer cosmetic.
- **Vehicle Stunt Mode** (Tony Hawk-inspired): vehicle-acrobatic combo scoring
  with per-trick library (manual / jump / spin / flip / grind / wheelie chain);
  per-stunt-arena with ramps / half-pipes / canyon jumps / rails / airfield;
  Stunt-mode leaderboards.
- **Burnout-Crash Mode**: score-based crash damage with chain-reaction
  CrashBreaker mechanic; ≥ 20 authored crash junctions (intersection / highway
  merge / downtown / underpass / airport / mountain pass); per-vehicle Crash
  variants.
- **Trackmania-style Time Trial**: ultra-short laps with hard-platforming racing
  (loops / jumps / wallrides / vertical walls / impossible turns); per-track
  ghost line + global leaderboard; per-medal tiers (Bronze / Silver / Gold /
  Author); Track Editor + community track-of-the-day.
- Per-mode ranked ladder separate from main racing; per-mode signature events.

### Persistent World Economy, NPC Schedules, Crime Rate

**Persistent economy.** The open world runs a server-side market that ticks once
per hour. Per-cosmetic supply/demand shifts a daily shop rotation off
community-wide purchase data — a high-demand rare item costs more, a slow seller
drops — and vehicle parts rotate on the same supply model. An anti-bot
classifier watches for rapid alt-account farming and pump-dump manipulation on
player-driven prices; a flagged account is blocked from the market. World-state,
including market participation, persists per account across cross-platform play.

**NPC schedules.** Each NPC runs an authored daily routine — commute, work,
lunch, leisure, sleep — and NPC schedules tick every 5 minutes. Per-district
population density varies by time of day, NPCs react to the player, the player's
vehicle, and faction allegiance, and an NPC may host an interactable mini-quest
or act as a vendor.

**Crime rate.** A per-district crime gauge aggregates player and NPC criminal
activity over 24-hour windows; cop spawn density follows the gauge, and
per-district faction influence shifts the crime profile. An extreme crime rate
triggers a district-wide police-lockdown cinematic.

**Events and ops.** A dynamic event rotation uses a per-day random seed shared
across players for fairness, with a per-event rare-item drop pool. An economy
ops dashboard tracks inflation, deflation, cosmetic-price distribution,
inventory turnover, and crime-rate trends so live-ops can detect and correct
runaway prices.

## Part 9 — Platform, Production & Compliance

Part 9 covers everything that makes V2 shippable and lawful: parental controls
and accessibility, localization, telemetry, display tech and performance, asset
budgets, patching and DRM, studio production, the compliance and privacy
program, balance and engineering operations, studio wellness, VR / AR support,
and hardware peripherals. It closes with the launch-readiness gate and the V2
exit criteria.

### Localization & Voice-Over, Region Rating Variants

**Locales.** V2 launches in 18 locales: English (US/UK), French (FR/CA), Spanish
(ES/LATAM), Portuguese (BR/PT), German, Italian, Polish, Russian, Turkish,
Arabic (UI; VO under consideration), Hebrew (UI), Japanese, Korean, Simplified
Chinese, Traditional Chinese, Thai, Vietnamese, and Indonesian. All strings are
externalized; the UI supports RTL layout for Arabic and Hebrew and a font
fallback chain so a missing glyph never renders as tofu.

**Voice-over.** A VO recording pipeline runs composition → recording → loudness
normalization → Opus encode → per-fighter bank version, with budgeted iteration
and pickup sessions. Per-fighter VO banks ship for ≥ 8 locales at launch;
remaining locales are subtitle-only with a documented VO patch plan, and
per-fighter banks hot-swap on patch without a full reinstall.

**Region content.** Per-region content rules — gore reductions, finisher swaps —
are stored in a `RegionVariant` data asset, and a region-specific cook produces
a tagged SKU per region; missing region data defaults to the most-restrictive
profile. Region rating variants: Germany (USK 18, gore-restricted), Japan (CERO
Z, reduced dismemberment), Russia / CIS (legal branch), China (separate
publisher SKU, skeletal / political-symbol filter, minor time-limit), Saudi
Arabia / GCC (alcohol / gambling adjustments), Korea (GRAC chat filter, loot-box
disclosure), Australia (ACB R18+), New Zealand (OFLC R18), and Brazil (DJCTQ
18 + Portuguese BR VO).

### Telemetry, Analytics, Balance

**Event schema.** Telemetry covers match start / end, move usage, damage dealt
and received per move, combo length, meter usage, finisher trigger rate,
rage-quit, crash, and frame-budget exceedance. Events publish on canonical
`v2.match.*`, `v2.cosmetic.*`, and `v2.player.*` topics — there is no V2-only
ingest endpoint. A per-session sampling rate is randomized from 1-100%, but
crash and cheat events are always sampled at 100% so a safety-relevant event is
never dropped to sampling.

**PII handling.** A per-field PII allowlist strips raw IP, raw device
fingerprint, and real-name fields at ingest so they never reach the analytics
warehouse; per-region routing keeps EU / JP / KR / LATAM / CN player data in the
correct residency zone. Telemetry opt-out persists across a save reset and is
documented and localized in the privacy policy.

**Balance analytics.** Dashboards surface pick rate, win-rate-on-hit,
win-rate-on-block, frame-data drift, and hot/cold character heatmaps. A balance
change goes through an A/B framework on the PTB branch before live, with a
rollback path; an ML recommender flags a candidate buff/nerf only on a ≥
5,000-match sample at the target rank tier with a ≥ 5 pp win-rate delta and ≥
0.95 matchup confidence, and a designer reviews every recommendation — none
auto-applies.

**Diagnostics.** Ghost data capture and sharing are opt-in. The crash reporter
is symbolicated; dev builds run in-the-loop fault injection to exercise crash
and recovery paths before they reach players.

### Production: Studio Ops, Mocap, VO, Composer, IP / NIL / Licensing, Stunt

V2 is a multi-year, multi-studio production gated by a Greenlight → Alpha → Beta
→ Gold-master milestone sequence; each gate has documented exit criteria, and a
post-launch first-30-day plan follows Gold.

**Studio organization.** An org chart is documented per discipline (design,
engineering, art, animation, audio, narrative, VO, QA, release, ops, marketing,
legal, accessibility, localization, esports ops). External studios integrate per
discipline under master service agreements with asset-delivery SLAs and
IP-assignment clauses. Per-fighter staffing rotates: each principal fighter gets
a dedicated mini-team while mid-roster fighters share a pool team.

**Mocap pipeline.** Mocap studio operations cover a booking calendar, a
stunt-double roster, SAG-AFTRA union compliance, insurance, and on-set medic and
safety protocols. The data pipeline runs capture → cleanup / contact-root repair
→ retarget to the V2 skeleton → curve/keyframe edit → engine import; every
capture first clears active consent and a NIL link before ingest, and a
revocation blocks future processing for dependent clips. Session footage is
archived for the behind-the-scenes gallery.

**Voice and music.** VO is cast per fighter per launch locale (≥ 8 locales),
scripted from the dialogue spreadsheet, recorded on a booked booth schedule with
a pickup-session budget and a per-locale VO director; per-locale banks are
versioned and hot-swap on patch. A lead composer plus per-ruleset sub-composers
produce ≥ 60 unique launch tracks including per-fighter signature themes and
license-cleared hip-hop for the DJ ruleset; the music library is DMCA-safe, with
per-locale remixes where culturally appropriate, and the soundtrack releases as
a separate consumer product (vinyl / digital).

**Rights.** Original characters carry trademark and copyright; licensed guests
sign term / royalty / removal-clause contracts; real-world fighters sign NIL
agreements with hide-on-request; stunt performers receive credit and residuals.
A per-jurisdiction publicity-rights review runs, and estates may opt likenesses
out. Music and SFX clear mechanical, sync, and master rights with hip-hop
sample-clearance, and only commercial-use (non-royalty-bearing) SFX libraries
are used. A per-asset rights manifest is verified at cook so no asset ships
without cleared rights or original-IP status. Brand partnerships ship with
disclosure requirements and per-region visibility caps.

### Compliance Deep: GDPR / CCPA / DSA / DSAR / Data Portability

V2 honors data-subject rights as a first-class product surface:

- **Per-account data subject rights UI**: Access, Rectification, Erasure,
  Portability, Restriction, Objection — operational in 30d (EU) / 45d (CCPA)
  SLA.
- **Granular consent management** with explicit, withdrawable opt-ins per
  processing purpose.
- **GDPR** compliance (DPO designated, lawful basis documented, 72h breach
  notification, EU-only data residency option).
- **CCPA / CPRA + state-level US privacy laws** (CO / VA / CT / UT / TX / MT)
  with Do-Not-Sell / Do-Not-Share opt-out.
- **EU DSA**: Statement of Reasons API for moderation actions, Trusted Flagger
  program, semi-annual transparency reports, out-of-court dispute resolution
  path, systemic-risk assessment.
- **EU AI Act compliance** for adaptive AI, AI commentary, anti-cheat
  classifiers, and AI generation pipelines — each service has a
  `V2/docs/ai/model-cards/` Model Card hosted by `@nous/safety` and a conformity
  audit export owned by `@themis/accountability`.
- **Per-region data residency**: EU / Japan / Korea / LATAM /
  China-publisher-SKU separated storage; cross-region transfer mechanism
  documented (SCC / BCR).
- **In-game DSR form** with 2FA auth; `@v2/themis-privacy-dsr-routing` sends
  Access / Erasure / Portability / Rectification through `@themis/privacy` and
  `@oshun/data-residency`; portability JSON export includes full profile / match
  / telemetry / cosmetic / friends / replay metadata; erasure preserves
  anonymized aggregates where lawful.
- **V2 audit routing**: moderation, anti-cheat, and DSR publish canonical events
  through `@oshun/audit-platform`; V2 publishes and Oshun retains and exports
  the investigation-ready audit record.
- **V2 service observability**: every `apps/v2/*` package and the `V2Services`
  Unreal module wire `@oshun/metrics` and `@oshun/tracing` as required from day
  one; the observability path is off rollback.
- **Concordia substrate composition**: anti-cheat appeals, tournament-result
  disputes, and crew conflicts use `@v2/concordia-substrate` to compose
  `@nous/cooperative-bargaining`, `@nous/preference-inference`,
  `@nous/agreement-search`, `@nous/concordia-sealed-memory`, and
  `@iris/concordia-assistant` plus `@oshun/concordia-integration` and
  `@kuanyin/concordia-restorative` while `@concordia/*` remains planned-only.
  Iris scaffolds appellant / arbiter dialogue through party-isolated prompt
  contexts and sealed private-context refs; Oshun routes privacy-projected
  Concordia events into V2 nav, audit, and telemetry descriptors; Kuanyin gates
  high-impact anti-cheat appeal restorative circles behind safety checks.
  `@oshun/config` owns external launch exposure through
  `ENABLE_V2_CONCORDIA_SUBSTRATE`, which defaults disabled while internal
  off-rollback composition checks continue.
- **Cookie / consent banner** on web (TCF 2.2; granular per-category opt-in).
- **Children's data minimization** + per-region minor protections (COPPA /
  GDPR-K / Korea GRB / China minor / Australia eSafety / Quebec Bill 25).

### Balance Operations: Tier List, Matchup Chart, Public Frame Data

**Published tier and matchup data.** Each major patch publishes an official tier
list with rationale and suggested counters, plus a per-rank-tier sub-tier-list
because what is strong at Bronze differs from what is strong at Master. A
matchup chart is auto-generated from match-result data with per-rank-tier
variation and an optional per-stage variance view.

**Public frame data.** Complete runtime frame data publishes to the `/v2/wiki`,
`/v2/glossary`, and `/v2/roadmap` knowledge pages and the companion app, backed
by cited RAG answers, plus a raw CSV download and a per-patch frame-data diff
visualizer. The published data is exported from the same spreadsheet-of-truth
that drives runtime data tables, so the public frame data and the live game can
never disagree.

**Patch cadence and process.** Buff/nerf changes ship on a monthly-major,
bi-weekly-minor cadence. A 2-week balance freeze precedes each major, during
which a pro-player feedback channel runs a pre-patch consultation. Each fighter
keeps a public changelog at `V2/balance/changelog/<fighter>.md`, and a 2-week
community comment window opens after every patch. An ML balance recommender
proposes candidates with telemetry justification but is designer-reviewed and
never auto-applied; the A/B framework validates changes on the PTB branch first.

**Player feedback.** An in-game balance survey runs post-patch, with additional
tournament-specific polls feeding the balance team.

### Engineering Polish: PSO Pre-Cache, Shader Pre-Warm, Asset Pre-Load

- **PSO pre-cache** at first launch enumerating every shader / pipeline state
  used in first 5 minutes; per-platform PSO blobs shipped pre-compiled;
  per-driver-upgrade rebuild.
- **Shader pre-warm** dummy-rendering every variant; per-cosmetic-pack pre-warm
  on load.
- **Asset pre-load on save-game open** + smart pre-load based on player session
  pattern.

  60Hz sim; ranked / tournaments 60Hz mandatory.
- **V-Sync** default-on for console; **VRR** auto-toggles when a
  variable-refresh display is detected; **NVIDIA Reflex** and **AMD Anti-Lag 2**
  are enabled for input-lag reduction; triple-buffered render with frame-pacing
  tooling.
- **Async asset streaming + async save** during match (low-priority worker
  thread).
- **Background services** (Battle Pass tier-up, Mastery level-up, Achievement
  progress, Friend list refresh) on dedicated worker thread; background download
  with bandwidth throttling.
- **Dev-only performance overlay** + per-platform Performance Mode preset.
- **Per-session telemetry sampling** randomized 1-100% with crash + cheat events
  always 100% sampled.

- **Erasure audit trail** with anonymized retention.
- **Privacy ops on-call** rotation for breach response.

### Studio Wellness: Crunch Policy, Mental Health, Sensitivity Reading, DEI

- **No-crunch commitment**: 40-hour-baseline week with documented exception
  process + mandatory comp time; weekly hours monitored; PTO mandatory
  minimums + carryover caps; weekend / holiday work prohibited except for
  designated on-call.
- **Mental health support**: EAP + crisis line + mental health days separate
  from PTO + trauma-informed workplace for staff handling sensitive content.
- **Sensitivity readers** per cultural / ethnic / gender / religious /
  disability identity for narrative + character / costume / lore review;
  per-fighter cultural review sign-off documented.
- **DEI consultancy partnership** for hiring + content + community management.
- **Accessibility consultancy partnership** (AbleGamers / similar) with
  per-feature review gate.
- **Transparent compensation bands** + bonus / equity / royalty structure
  documented.
- **Zero-tolerance harassment policy** with anonymous reporting + independent
  ombudsperson.
- **Remote / hybrid work** with time-zone respect + async-first culture.
- **Wellness budget** per employee + studio-wide quarterly wellness day.
- **Realistic scoping discipline**: feature scope is sized to the staffed,
  no-crunch schedule, and milestones are descoped rather than crunched when
  estimates slip — protecting both shipped quality and team health.

### VR / AR Support: PSVR2 / Quest 3 / Vision Pro

- **VR ruleset compatibility matrix**: racing rulesets all VR-eligible; fighting
  rulesets toggle-able with motion-sickness considerations.

### Launch Readiness

V2 launches only when every gate below is satisfied; the gates are verified, not
asserted, and a failed gate blocks the launch date.

**Feel and netcode.** All seven inspirational rulesets are verified to feel like
their sources by an external playtest staffed with veterans of each franchise.
Rollback netcode delivers 1v1 play at ≤ 100 ms RTT that is indistinguishable
from local play at ≤ 30 ms.

**Content completeness.** Every launch-day mode delivers a complete experience
with no "coming soon" panels. Story, MyCAREER, MyRISE, Universe, MyGM,
MyFACTION, GOAT Career, Tekken Force, Devil Within, Chronicles of the Sword, Def
Jam Story, World Tour, and Battle Hub are content-complete. The roster is ≥ 60
fighters, stages ≥ 30, and ruleset coverage spans all inspirational families.

**Stability and operations.** Internal dogfood has run ≥ 60 days across every
mode and platform; a closed beta has hit measurable targets for concurrent peak,
matchmaking time, rollback frame distribution, crash rate, and anti-cheat
false-positive rate. A network stress test has passed at 5× launch-estimated
concurrency. Accessibility, performance, security, anti-cheat, observability,
runbooks, canary analysis, rollback triggers, and post-deploy monitors all
satisfy their launch gates; a per-platform and per-service rollback plan is in
place, and the day-one patch is staged.

**Compliance.** Rating boards have approved the build with regional content
adjustments cooked per region, and critical-journey verification has run across
every advertised mode.

### Oshun Ecosystem Integration: Companion App, Public API, Knowledge Surfaces

V2 ships as a first-class citizen of the wider Oshun platform rather than a
walled-off game. Three surfaces bind it to the ecosystem, and all of them stay
strictly off the deterministic gameplay path.

**Public companion API.** A read-mostly public API is served from
`apps/oshun/web/api/v2/` (typed request handlers) through
`apps/oshun/web/src/app/api/v2/` (the Next.js route adapters) under the
`/api/v2` base path. The contract is generated from
`libs/openapi/v2/companion.yaml` and consumed through the shared
`@oshun/openapi` client so third-party tools, the in-game wiki, and the
companion app all read the same typed surface.

**Mobile companion app.** The companion app lives at `apps/oshun/mobile/v2/` and
is composed from existing platform libraries — `@oshun/shell-core` for the app
shell, `@oshun/auth-client` for cross-progression sign-in,
`@oshun/concordia-integration` for the shared identity substrate,
`@oshun/trust-safety` for reporting and moderation entry points, `@iris/agents`
for the conversational help agents, and `@sophia/client` for knowledge lookup.

**Sophia knowledge surfaces.** The in-app wiki, glossary, and public roadmap are
answered by `@sophia/client` retrieval-augmented generation, and every answer
renders inline source citations so players can trace a claim back to the
authoritative frame data or design doc.

**No-Stub commitment.** Every surface listed across this document ships fully
implemented at launch — no placeholder screens, no "coming soon" panels, and no
mocked backends standing in for real services. A surface that cannot meet that
bar does not ship in the advertised mode list until it can.

### V2 Exit Criteria

V2 is complete when every section in `V2_TODOS.md` is fully checked, including
P2/P3 full-vision expansion sections, AND the adversarial scan turns up zero
actionable hits AND launch-readiness drills have run across every target
platform. See `V2_TODOS.md` §138 for the launch gating checklist and
`V2/docs/agent-execution.md` for coding-agent workflow.

**Status (2026-06-12):** clause 2 is **pending** — no launch-readiness drill has
run on any platform; the repo holds a UE C++ source skeleton with a single
`.uasset` and no cooked or packaged builds, so the drill clause cannot yet be
satisfied. Concurrency gates in §138 are sized against the planning assumption
of 100,000 CCU launch-estimated global concurrency (5× = 500,000), adopted
2026-06-12 against SF6/MK1-scale launch peaks; revisit at beta.
