RimWorld is Ludeon Studios' sci-fi colony sim. You do not steer your crash survivors directly; you give them jobs, zones and priorities, and they live out their own needs, traits and relationships. What sets it apart from a typical builder is the AI storyteller that deals out raids, illnesses, passing traders and surprises.
This guide is for players building their first colony, starving through their first winter, or wondering why a colonist suddenly stopped working and locked themselves in their room. We stick to the base game without expansions or mods.
