RimWorld Odyssey DLC is the latest and most ambitious expansion to the legendary sci-fi colony simulation game. Launching alongside the free RimWorld update 1.6 in July 2025, RimWorld Odyssey DLC introduces a whole new layer of depth, mobility, and cosmic exploration that elevates the colony sim experience to stellar heights.
This RimWorld Odyssey DLC expansion isn’t just a content pack—it’s a complete reimagination of what survival and strategy mean in the RimWorld universe. If you’ve ever dreamed of building a colony that could lift off and explore faraway biomes and even space, Odyssey is your ticket.
Build and Command Your Own Gravship
At the heart of the RimWorld Odyssey DLC is the gravship, a fully customizable airborne base. Start small with basic propulsion and living quarters, then expand your flying fortress as you collect gravcores hidden in dangerous locations like insect-infested caves and derelict reactors.
Your gravship is more than just a transport system—it’s a self-sustaining, fully functional mobile colony. Equip it with oxygen systems, heating units, airlocks, and even laboratories. With enough upgrades, you’ll be able to explore low orbit, space wrecks, and asteroid mines.
New Biomes, New Challenges
Odyssey brings five brand-new biomes that radically shift survival tactics:
- Glowforest: Bioluminescent fungi and perpetual twilight demand fungus-based agriculture.
- Scarlands: Toxic rain and mutant beasts lurk in this biome of post-war ruins.
- Grasslands: Fertile and open—ideal for farming, but vulnerable to wind-driven wildfires.
- Glacial Plains: Hostile tundra with roaming mastodons and hidden ice caves.
- Lava Fields: Constantly shifting rivers of molten rock and suffocating ash clouds.
Each biome introduces unique weather systems, hostile wildlife, and resource dynamics, making every landing a new survival puzzle.
Epic Quests and Orbital Adventures
Odyssey integrates a dynamic planetary quest system that sends players on missions discovered via maps, signals, and travelers. Highlights include:
- Alpha Thrumbo Hunt: A legendary creature with a priceless horn.
- Orbital Scavenging: Compete against rivals to loot abandoned satellites.
- Mercenary Crypt Raids: Break into Glitterworld caches guarded by cryo-soldiers.
Even asteroid mining becomes a high-risk, high-reward endeavor. But beware—pirates and hostile drones roam space too.
Wildlife Gets Wild (and Smart)
With over 40 new animal species, Odyssey lets you train, tame, or eat a broader variety of fauna. From cute prairie dogs to majestic scimitar cats, animals now:
- Assist with foraging and digging
- Offer comfort and emotional support
- Can be enhanced using sentience catalysts to boost intelligence
You can even go fishing, netting exotic species like marlin and deep-sea curiosities.
New Enemies, Weapons, and Gear
Prepare for battle with a fresh arsenal:
- Golden revolvers, AI-enhanced scopes, and sawed-off shotguns
- Hunter drones and wasp drones with explosive or paralyzing attacks
- Cyclops mechanoids with devastating gamma beams
Defensive structures and traps now play a critical role in protecting both your stationary base and gravship.
Face the Mechanoid Hive Mind
RimWorld Odyssey DLC’s late-game arc builds toward a confrontation with the mechanoid central intelligence. Will you destroy this ancient AI and end the mechanoid threat—or seize control of its power?
This moral and tactical dilemma adds a powerful narrative layer to the already rich storytelling sandbox of RimWorld.
Free RimWorld update 1.6: More Than Just a Patch
Even without the DLC, RimWorld players benefit from a significant free update:
- Performance improvements
- Base-building QoL changes
- Flying chickens, new maps, and more variety
You can view the full list of 1.6 features on the RimWorld Steam page.
