From pioneers to scientists
Your residents rise through technicians and engineers as you supply them. More tiers, more taxes, more options, all the way to a hotel for guests from Earth.
Mission status · In development
Build your colony in space. Piece by piece.
A city-builder and economy game with real depth: bases on the Moon and Mars, production chains, residents with demands, and a rocket you fuel and launch yourself.
The journey
Every location is its own map with its own resources, its own bottlenecks and its own dangers. And every act is a little harder than the last.
Horizon Bay · Earth
Turn natural gas and air into propellant, stack and fuel the rocket, launch it and catch the booster again.
Moon
Ice, regolith and helium-3. Land, set up power, air and heat, and turn an outpost into a colony.
Mars
CO₂ from the air, methane made on site, and dust storms that swallow the sun for days. The goal: a colony that sustains itself.
The heart of it
It is bottleneck, goal and spectacle in one. Every cargo, every resident and every tonne of freight arrives with it. And it only flies if your fuel chain is running.
A look inside
Sober industry instead of cartoon domes. Every pipe, every store and every bottleneck is visible, and for every problem there is a building that solves it.
What awaits you

Your residents rise through technicians and engineers as you supply them. More tiers, more taxes, more options, all the way to a hotel for guests from Earth.

Power, heat, air, food, comms, medical care, recreation and a lab nearby. If one fails, you'll know right away.

Regolith, ore, ice and sunlight become metal, water, oxygen and propellant. Storage has limits, roads have lengths.

Find ore fields, ice and abandoned wrecks. Careful: rovers need power and air, and must head home in time.
Fair
The prologue is free. Buy each act once. Extra styles only change the looks, never the game.
