A sci-fi colony sim driven by an intelligent AI storyteller.

RimWorld follows three survivors from a crashed space liner as they build a colony on a frontier world at the rim of the galaxy.

Alpha 4 has been hotfixed to Alpha4c.

Alpha4b added the source code which is supposed to be included.

Alpha4c fixes the storytellers, who had a bug that made them permanently placid instead of ramping up over long games. Now they will ramp up properly and eventually, probably, kill you. But hey, it’s all about the drama!

Sorry about that. Testing storytellers properly is hard because it takes so long and the results are so noisy. Your savegames from Alpha 4 will still work.
