About Astrominer
AstroMiner is about a robot stranded in an asteroid belt after a crash landing. You build a base, gather materials and craft what you need to establish communication with Earth and construct a spacecraft to return home.
Explore the asteroid belt
The asteroid belt is procedurally generated, creating a new world each time you play. Its biomes include Lava, Gold and Stone, each with its own advantages. You explore the belt to find the materials needed for your journey home, and can leave your robot to explore on foot, dig tunnels sized for it or fly buildings to move them.
Build and craft
Different structures unlock different crafting options: Chests and a Forge open up additional crafting choices. You can make Turrets, Doors, Elevators, Pipes and Buckets, among other items, to help you get home.
Return to Earth
Once you have enough materials, you complete minigames to deploy Antennas, establish communications with Earth, align your rocket and fly home.
