Free mods for PC games, with the source open so you can read exactly what runs on your machine.
Every repository here holds the code, tests and build files for the mods we publish for one game. All of it is MIT licensed. The mods themselves are free; download them from the places players use:
- All our mods, by game: mods.offtheclocksoftware.com
- Nexus Mods, plus Steam Workshop (per-mod links are on that list)
- Thunderstore for Risk of Rain 2

How we make mods
- Single-player and co-op only. Nothing touches other players, online modes or leaderboards.
- Settings start at the game's own values; each mod page says plainly what it changes, including saves and achievements.
- Every release passes automated checks (a linter and an offline test harness) and an unattended in-game run before it goes up.
- We build with AI-assisted tools, and every release is tested before publishing.
Found a bug? Please report it on the mod's page (Nexus Mods or Thunderstore) with your game version and what you did just before it happened; that is where we answer fastest.
Game names and trademarks belong to their owners. Our mods are unofficial fan mods, not affiliated with or endorsed by the developers.
