About This Game

Earth is dying, and you are the AI entrusted with building a generation ship for humanity. In this real-time colony and space simulation, sustain a living crew and fly supply missions using real orbital mechanics. Earth supports you at first, but as its supplies dwindle, your ship must become self-sufficient.

Build your colony ship

Design your ship room by room, from its first modules to a vast spaceborne habitat. Your crew fetches materials from storage, carries them to the build site, and constructs every room and item. Follow their work in real time or accelerate to months per second while the simulation keeps running.

Give your crew a home

Make room for meals, sleep, conversation, and a shower after a long shift. Set daily schedules and organize your crew into groups with their own uniform colours. The people keeping your ship running need a life aboard it.

Recycle everything

Grow vegetables, prepare meals, and process the crew’s waste into soil for the next harvest. Keep oxygen, water, and power flowing through a colony whose systems depend on one another. Every loop you close reduces your reliance on Earth.

Create artificial gravity

Build a vast rotating ring to generate artificial gravity for your crew. The habitat’s motion turns the ship itself into part of the life-support system.

Fly your supply missions

Plan and fly the missions that keep your growing ship supplied. Stage rockets, shape their orbits, and bring them in for a rendezvous and docking. Real orbital mechanics turn every delivery into a spaceflight challenge of its own.

Establish outposts

Mine raw materials on other worlds and turn surface outposts into supply bases for your growing ship. Extract and process local resources, then send supply ships back and forth with the materials your colony needs—reducing what you must launch from Earth.

Keep humanity alive

Face meteor impacts, fires, and failures of power or atmosphere. Your crew responds to emergencies aboard the same ship they build and inhabit. Keep life support working while they fight to bring the situation under control.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Generationship was built entirely by hand until 2026, over more than five years of development, and that work is still the foundation of the game. Since then, generative AI has been part of our daily development:

- 3D models: newer models are AI-generated.
- Voice: voice lines are created with text-to-speech.
- Images and text: artwork, translations and news posts are AI-assisted.

AI also assists with programming and testing. Everything is carefully reviewed by hand, using custom tools we built for this and often over many iterations. Nothing is generated by AI while you play.
