About This Demo

The Astromine demo contains the first planet and moon of the game and can be played in online co-op.

Astromine is a co-op survival game set in a fully destructible voxel solar system. Every planet, creature, and structure is made of voxels with real physics. Dig through worlds, collapse walls, burn bases, and carve into alien monsters.

Procedural Voxel Planets

Land on fully destructible, procedurally generated planets—each a spherical world with its own terrain, resources, and hazards. Dig through alien crusts, tunnel into the core, and strip planets for the raw materials you’ll need to survive and expand.

True Physics Survival

Every material has real physical properties. Wood burns and collapses under stress, iron supports towering structures, and electricity powers sprawling networks. Fires spread, bases crumble under weak foundations, and survival demands engineering as much as scavenging.

Robot vs. Robot Warfare

You are a machine in a war for the solar system. Rival robot factions control fortified bases across alien worlds. Each outpost is a challenge of planning and destruction: breach walls voxel by voxel, disable power sources, and tear down defenses piece by piece.

Living Alien Worlds

Alien life is voxel-based too. Blast through flesh and armor, carve into enemies to find their weak points, and watch as your weapons physically tear them apart

Build, Expand, Conquer

From survival shelters to orbital fortresses, construct bases and starships from voxel materials with full physics. Pilot your ships between planets, expand your territory, and fight for control of the solar system.
