RimWorld – Odyssey reimagines the colony sim genre with a new expansion that lets you build and command your gravship. Whether you want to explore treacherous lava plains, hunt down orbital relics, or tame exotic wildlife, it delivers adventure and danger in equal measure. It's a new way to play RimWorld. 

In RimWorld – Odyssey, the gravship is your gateway to endless discovery. Starting as a modest flying base, it can eventually become a self-sustaining fortress in the sky. You must scavenge, fight, and adapt as you upgrade your vessel and crew, gradually evolving from a grounded survivalist to a galaxy-roaming explorer. 

Discover a living, dying world 

Discover a living, dying world 

RimWorld - Odyssey introduces a range of new biomes, each with unique environmental challenges and strategic opportunities. The glowforest’s surreal spores require fungal farming, while the scarlands constantly punish your colonists with toxic rain and mutant predators. More forgiving locales, like grasslands or glacial plains, offer their difficulties—droughts, wildfires, and prowling beasts. The ever-changing landmarks system ensures that no two expeditions feel the same. 

Gravship gameplay dramatically shifts your colony’s dynamics. You must collect rare gravcores in perilous ruins, carve out cliffside colonies, and transform shipwrecks into functional outposts. With your mobile base, you can raid mechanoid-ridden reactors or establish fishing villages on fjords. Every new site offers treasures, dangers, and endless narrative potential through emergent gameplay—the game thrives on player creativity and risk. 

Even the stars aren’t safe. With airtight walls, oxygen pumps, and vac suits, your ship can venture into orbit. You must explore wrecked satellites and asteroid mines, fending off rival scavengers and ancient mechanoid defenses. Each mission into space is high-stakes and atmospheric, blending survival mechanics with tactical combat in a hostile, airless void. However, even for experienced RimWorld players, this DLC features a steep learning curve.

A fitting finale to the journey 

With dozens of new creatures, gear, and weapons, RimWorld Odyssey raises the stakes of the game without overwhelming the core gameplay. It’s a detailed expansion that rewards planning, courage, and curiosity. Whether you're hunting the alpha thrumbo or unlocking ancient gravtech, the game turns every choice into an unforgettable story.
