What you’ll build

Each stage hands its routine work to automation and opens the next place. These four are playable in the current build.

A late-game Earth economy: wind farms, solar fields, materials plants and a fusion campus — 1
Earth industry
Power, Materials and research on a real globe, placed where the land allows.

The orbital station: a ring of depots, habitats and a shipyard above Earth — 2
Orbit
Launch pads lift cargo to a depot; the station grows berth by berth.

A lunar base with solar arrays, ice mines and an electrolysis plant linked by roads — 3
The Moon
Polar ice becomes propellant, so landers fly home full.

An asteroid mining base with solar panels and a smelter on a grey rubble pile — 4
Asteroids
Tugs haul Materials out and bring iron and nickel home.
