RimWorld

A sci-fi colony simulator driven by an AI storyteller, now available for your Mac.

RimWorld places you in command of three survivors who crash-landed from a space liner, tasking you with building a thriving colony on a frontier world at the very edge of known space. The creative inspirations behind this game include the space-western spirit of Firefly, the incredibly deep simulation mechanics of Dwarf Fortress, and the epic, sprawling universes of Dune and Warhammer 40,000.

Monitor the moods, needs, thoughts, wounds, and illnesses of each of your colonists as they struggle to survive. Engage in deeply simulated small-team combat encounters that demand careful tactical planning. Craft and utilize clothing, weapons, and equipment fashioned from metal, wood, stone, fabric, and exotic futuristic materials. Battle ruthless pirate raiders, hostile tribal factions, ferocious wild animals, and ancient killing machines lurking beneath the surface. With every new playthrough on your Mac, discover a procedurally generated world that feels entirely fresh. Build and expand colonies across diverse biomes ranging from scorching deserts to dense jungles and frozen tundra, each featuring its own unique flora and fauna ecosystems. Manage your colonists and help them grow through their unique backstories, individual traits, and developing skill sets. The rimworld mac experience is enhanced by an intelligent and unobtrusive AI tutor that helps you learn the mechanics naturally without overwhelming you. You can also explore rimworld multiplayer through community mods for cooperative colony management with friends.

RimWorld was developed by Tynan Sylvester and Ludeon Studios. Since its initial early access launch on November 4, 2013, the game has been continuously improved and refined.
