About This Demo

Dig and build

Dig and build wherever you want in a procedurally generated world. Design multi-level water, gas and electricity systems that power your colony.

Research and automate

Unlock core technologies that help you survive and expand your colony. Offload the hard work to machines and let your colonists explore the boundaries of technology.

Build robots

Start with small rover robots that help your colonists dig. Then expand to flying delivery drones, and finally build humanoid androids that can do any task.

Farm and tame

Grow alien crops whose seeds carry their traits into the next generation. Lure wild animals in with fodder and keep them in pens.

Survive the weather

Dust storms, rain and snow will challenge your colony’s fortitude and preparedness.

AI Generated Content Disclosure

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

Storepage capsule images, sound effects, and localization are made with AI. Most assets in the game are originally made by human artists. However I still adjust 3D models and retexture them, this way the game has smaller file size and runs more smoothly. For example: a small mining rover was 1Gb in its source but now it is 12Mb and I generated a small laser turret on top of that.
