Ludeon Studios has officially launched Odyssey, the fifth and most ambitious expansion yet for the beloved sci-fi colony simulator RimWorld. The expansion catapults the game to new heights, literally, by allowing players to leave the planet's surface and explore the mysteries of orbit and beyond.

A path through the stars

At the heart of RimWorld - Odyssey is the introduction of gravships, customizable flying bases that let players move their colonies across the world or even into space. These ships rely on rare gravcores to function, which can only be scavenged from dangerous locations like insect megahives, asteroid fields, or derelict space wrecks. With a gravship, colonists can land anywhere, opening up a radically different way to play. The expansion also brings five distinct new biomes into play: the radiant Glowforest, scorched Scarlands, vast Grasslands, icy Glacial Plains, and treacherous Lava Fields. Each biome comes with its own ecosystem, weather hazards, and strategic considerations. Players will also encounter a wide range of new landmarks, such as volcanic ridges, geothermal cliffs, abandoned ruins, and crashed satellites.

Wildlife diversity has been supercharged in RimWorld - Odyssey, with over 40 new animals added. Colonists can now encounter and tame everything from cuddly therapy pandas to genetically modified alligators, massive prehistoric creatures, hive queen insects, and even "bog hounds", a mysterious new species with yet-unknown abilities. Many animals can now be trained for specialized tasks, such as foraging, mining, or even combat. Gameplay systems have also been meaningfully expanded. Colonists can now fish from rivers and oceans, catching everything from trout and salmon to marlin and jellyfish. Swimming has been added as both a survival and recreational activity. A new animal training system allows creatures to assist colonists in unique ways: megasloths can mine rock, mastodons can trumpet enemies into retreat, and advanced neurotech injections can boost animal intelligence.

As colonies ascend into space, they'll eventually confront the new endgame threat: a hostile mechanoid hive mind lurking in orbit. Players can launch raids on orbital platforms, asteroids, and ancient installations, scavenging for tech, battling enemies, and uncovering deep lore. These encounters culminate in a high-stakes confrontation with the mechanoid collective, whose fate rests in the hands of the player.

The community response has been overwhelmingly positive. Odyssey has already helped RimWorld smash its previous Steam player count record, with nearly 67,000 concurrent players at launch. On platforms like Reddit and ResetEra, players are hailing it as the most significant expansion since the game’s inception, praising the depth and scale of content.

Between planetary exploration, interstellar travel, new animal companions, and a compelling orbital narrative, Odyssey reshapes RimWorld into a broader, deeper experience.
