📄 Description

New field note: Arkham Knight Batman as a Risk of Rain 2 survivor (knowledge/games/risk-of-rain-2/arkham-knight-batman-survivor.md), plus the regenerated index (one new row).

What it covers

Route: HenryTutorial (42797355, AC update) + BepInEx 5 + R2API split modules on RoR2 1.4.1#912. The Batman model and 51 animations are extracted from the player's own Arkham Knight install (UE3 863/32995) with umodel -game=batman4, rebuilt headlessly in Blender 5.2.2 (io_scene_psk_psa 9.1.3) and packed by a headless Unity 2021.3.33f1 AssetBundle builder.
Engine facts on both sides: where Batman's AnimSets really live, the cape skeleton's own hierarchy, root motion and victim-aimed attacks, RoR2's animator layout and aim cycles, AssetBundle script resolution through Assembly-CSharp type forwarders, Unity audio disabled in the player, and Loader's two hooks being the same controller code.
23 numbered gotchas (symptom -> cause -> fix). Among them: umodel's download needs a Referer; -groups for duplicate AnimSet names; the PSA translation scale; the PSA importer's pseudo-root quaternion convention; attaching cape clips to their anchors; BullseyeSearch DistanceAndAngle ranking the farthest target first; AI Hold drivers pinned on mustKeyPress skills; hand-built DamageInfo without inflictedHurtbox; the per-asset SteppedSkillDef reset timer.
Honest status: in-progress. The real-model build loads in game with no mod errors and the kit was verified on a placeholder model. The real-model animation quality, the latest fixes and multiplayer are not verified yet.

Checks: um kb check rules pass (0 fails, 0 warnings). The index diff is exactly the new row and the games count (46 -> 47). PyYAML wasn't installed here, so the existing index entries were kept verbatim and only the new row was added through build_index.

No game files, no ripped assets, no decompiled code, no secrets or personal paths.
