Humanity’s final voyage is in your hands
Earth is gone.
Your colony ship carries the last survivors of humanity through an unknown galaxy. As the ship’s artificial intelligence, you must keep its crew alive, investigate strange signals, and find a world where civilization can begin again.
Every voyage generates a new chain of planets, discoveries, dangers, and difficult decisions.
Each world with unique atmospheres, oceans, climate, moons, rings, surface formations, and signs of civilization all provide clues about what awaits below. Exact scanner readings may be incomplete, but the planet itself never lies. Will you spend a precious probe to learn more, risk a landing, or continue deeper into space?
Make impossible decisions
Along the way you'll encounter narrative events with lasting consequences. Respond to equipment failures, dwindling supplies, disagreements among the crew, scientific discoveries, alien encounters, and crises that may determine whether humanity reaches its destination intact.
Manage the systems and resources aboard the ship, including:
Hull, shields, navigation, cryopods, and landing systems
Fuel, energy, water, probes, and surviving colonists
Technology and scientific capability
Crew society, morale, and cultural identity
Relations with the civilizations you encounter
What you sacrifice along the way may matter as much as what survives.
Decode the unknown
Encounter scientific and communication puzzles inspired by astronomy, mathematics, and the search for extraterrestrial intelligence. Analyze spectral lines, interpret alien number systems, reconstruct transmissions, and distinguish meaningful signals from the noise of deep space.
The puzzles can reveal valuable knowledge or open a conversation with something waiting in the dark.
Discover living worlds
Procedurally generated planets combine atmospheric conditions, geography, civilizations, orbital systems, and distinctive surface features into an enormous variety of possible destinations.
Worlds may possess vast oceans, volcanic regions, electrical storms, crystal caverns, floating islands, ancient ruins, ghost cities, orbital debris fields, alien monuments, and other phenomena. Their appearance reflects their true nature, rewarding players who learn to read the visual evidence instead of relying solely on instruments.
Build humanity’s new home
Landing is only the beginning.
Your chosen world, the condition of the ship, the people you saved, the technology you preserved, and the relationships you formed all influence the colony that follows. See its government, society, culture, technology, construction, and relationship with native life develop through a detailed account of humanity’s new beginning.
A seemingly hospitable world can still destroy an unprepared colony. A hostile one might be overcome by exceptional preparation, technology, and sacrifice.
Every voyage leaves a legacy
No two expeditions follow exactly the same path. Earn Legacy Points, unlock permanent improvements, experiment with new strategies, revisit past voyages through the log, and share generated seeds with other players.
How far will you go to preserve humanity—and what kind of civilization will remain when the journey ends?
