Illustrated Bloombelt key art: a planted asteroid outpost with solar panels, a transport hub, greenhouses, and a garden beneath glass

An asteroid colony builder

A little life in a very big sky.

Build a living outpost on a spinning asteroid. Put crab-like robots to work, harness sunlight, connect colonies with automated freight, and grow gardens under glass.

The game

Make a home out of bare rock.

Every asteroid is a little world with its own terrain, rotation, and shifting light. Find room for the essentials, bring your first structures online, and watch an outpost take shape around the rock.

Bloombelt is about the systems that keep a colony growing and the pleasure of slowing down to watch it work. Follow your workers, watch freight cross the belt, or pull back to see what you've built against the stars.

What you'll do

Build. Connect. Grow.

01 / Build

Build around the rock

Fit storage, power, and gardens to an uneven little world. Crab-like construction workers travel to their jobs and bring each project together.

02 / Power

Work with the sunlight

Your asteroid keeps turning. Solar panels track the sun while terrain and rotation cast shadows. Balance generation, storage, and demand.

03 / Connect

Connect your colonies

Survey new rocks, establish outposts, and set supply targets. Automated freight carries resources between your settlements.

04 / Grow

Make room for green

Shelter plants beneath greenhouse glass and crater membranes. Tend the systems that turn a harsh patch of rock into a living place.

Stay and watch

Unwind in Terrarium Mode.

With Terrarium Mode, take a gentle tour through the belt and enjoy the outposts you've built. Follow your busy little workers, watch freight cross the void, and see sunlight sweep across your gardens. Settle in and let your little space terrarium come alive.
