Contruct your own gravship
Take to the skies and explore a vast world in your very own custom-built gravship! Start with just the basics — a grav engine, a few essential rooms, and enough chemfuel to get airborne — and turn it into a fully functional, flying colony complete with living quarters, labs, and workshops tailored to your crew's needs.
Touch down anywhere across the planet to scavenge for treasure, hunt for food and fuel, or collect one-of-a-kind items like exotic birds, ancient gravtech, or even a gold-plated charge rifle. As you journey through diverse and hazardous biomes, uncover hidden gravcores — the key to upgrading your ship and unlocking distant, perilous frontiers.
Whether you're exploring derelict orbital platforms, navigating insect-ridden caves, or dismantling trap-laden reactors, each expedition brings new challenges, discoveries, and rewards to shape your airborne odyssey.
About the base game:
RimWorld is a story generator. It’s designed to co-author tragic, twisted, and triumphant stories about imprisoned pirates, desperate colonists, starvation, and survival. It works by controlling the “random” events that the world throws at you. Every thunderstorm, pirate raid, and traveling salesman is a card dealt into your story by the AI Storyteller. There are several storytellers to choose from. Randy Random does crazy stuff, Cassandra Classic goes for rising tension, and Phoebe Chillax likes to relax.
