About RimWorld

RimWorld is a science-fiction colony survival simulation developed by Ludeon Studios. Players manage survivors stranded on an alien planet, building facilities, growing food, researching technology, and trading to keep the colony alive. An AI storyteller combines psychology, ecology, combat, weather, and other systems into unpredictable events and unique stories.

RimWorld is a science-fiction colony survival simulation developed by Ludeon Studios, founded by independent developer Tynan Sylvester. It received its full Steam release in October 2018 and draws inspiration from Dwarf Fortress, Firefly, and Dune. Players lead three survivors of a spaceship crash as they establish a colony on an unfamiliar planet. An AI storyteller controls random events, turning storms, pirate attacks, and visits from traders into parts of an evolving narrative. Players choose among three storytellers: Cassandra steadily escalates tension, Phoebe uses a gentler pace suited to newcomers, and Randy is entirely unpredictable. Colonists have layered needs including hunger, rest, and mood, as well as distinct backgrounds, personalities, and professions. A noble may refuse manual labor, a scientist may excel at research but struggle socially, and a genetically modified assassin may be formidable in combat but unable to perform other work. Colonists can become friends, lovers, or spouses, but may also argue, betray one another, or separate. Systems include construction, crafting, trade, diplomacy, animal training, and combat. Players can fit injured colonists with prosthetic or mechanical body parts, train animals to help with work, send caravans across the planet, and expand the population through recruitment, purchase, rescue, or capture. Procedurally generated maps give each biome its own wildlife, vegetation, temperatures, and resources. RimWorld presents itself primarily as a story generator designed to create tragic, twisted, or uplifting narratives together with the player.
