MW2 x Risk of Rain 2 (MW2xRoR2)

Adds a Risk of Rain 2 survivor that plays with Modern Warfare 2's own movement, weapons, HUD and killstreaks.

What it does

A BepInEx mod that adds the MW2 Soldier to Risk of Rain 2. MW2's player movement and weapon handling (fire timing, recoil, spread, ADS, reloads) run in a Rust library built on IW4L's crates, loaded in-process, while RoR2 keeps damage, items and enemies, so RoR2 items proc off MW2 guns. Guns, attachments, camos, viewmodel, animations, sounds, HUD, minimap and menus are read at runtime from the player's own MW2 install. Includes Create-a-Class, perks as RoR2 items, deathstreaks, all 15 killstreaks, MW2 XP/ranks/challenges and co-op through RoR2 lobbies. v0.4.4 (2026-10-11) targets RoR2's 8 Oct 2026 update and fixes a co-op desync between mod-manager and manual installs.

How it works

Rust MW2 simulation library (IW4L crates via chasmlol's 2010 Rust Rewrite Mashup) loaded in-process by a BepInEx plugin; MW2 assets read from the player's own install

Requirements & limitations

Evidence limits

On 2026-10-12 I read the repository README, LICENSE.md, tags and GitHub releases page (v0.4.2-v0.4.4, latest 11 Oct); Thunderstore could not be reached from the review environment, so that listing rests on the creator's README and issue #4. No play-test.
