Odyssey Build your own ship and travel across the planet! Land anywhere you want to hunt for treasure, harvest food and fuel, and bring back souvenirs like exotic birds, long-forgotten gravtech, or a gold-plated charge rifle. Your gravship starts small - just a grav engine, a few rooms, and enough chemfuel to lift off. But over time, it will become a home: a travelling colony of labs, living quarters, workshops, and anything else your colonists need. Collect rare gravcores to expand your gravship and travel further. You’ll find them in crashlanded orbital platforms, insect-infested caves, broken-down reactors rigged with traps, and other dangerous locations.
