Risk of Rain 2
Unity / C# · PC / offline assessment
Possible. Expect some experimenting.
- R2API offers APIs for community mods.
- Installed game, loader and module versions need checking.
- Online sessions are outside this assessment.
Use R2API in an isolated profile after checking current compatibility.
What you’ll need
- A licensed PC copy and a separate save backup
- Claude Code or another supported coding agent + universal-modder
- Python 3.10+ and ffmpeg (uv recommended)
- Compatible community loader and R2API modules
- A new local solo run
Only if your idea needs it: fal API key for generated art (billed by fal) · Blender for 3D-to-sprite renders
Your starting prompt
COPY → PASTE → BUILDPaste this into Claude Code with universal-modder installed.
Use universal-modder to plan a small Risk of Rain 2 mod for my own offline single-player PC copy. Plan one original item for a local solo run using only the required R2API modules; validate compatibility before implementation. First confirm my exact game build and compatible tools, back up my saves, and explain the files you would change. Ask before installing a loader or changing game files. Stop if this requires anti-cheat or DRM bypass. Do not connect to multiplayer. Give me a reversible plan and a concrete in-game verification step.Under the hood Engine details & sources
Unity / C#: R2API exposes game-specific modules; game updates and DLC affect dependencies.
