How to try itHow to install and play MW2 x Risk of Rain 2 (the MW2 Soldier as a RoR2 survivor) · about 15 minutes
MW2 x Risk of Rain 2 adds the MW2 Soldier as a Risk of Rain 2 survivor. Its movement, guns, viewmodel and animations, sounds, recoil, HUD and menus are read from your own copy of MW2, while Risk of Rain 2 handles damage, items and enemies, so RoR2 items stack on MW2 guns. MW2’s Create-a-Class works through MW2’s own menus, perks show up as RoR2 items, and all 15 killstreaks are in, from UAV to the AC-130.
It’s a BepInEx mod written in Rust and C#, and the README credits IW4L’s crates for its movement, weapon, animation and data code. Some of MW2 is retuned for RoR2’s huge stages, such as faster movement, unlimited sprint and scaled damage, and each change is a setting. It’s Windows only, comes as a manual zip or a Thunderstore package (v0.4.3 on 9 October 2026), and credits Claude Opus 5.5.
