Zero Mass

Zero Mass is a space-mining incremental game in which you dismantle procedurally generated asteroids until their mass reaches 0%. You begin with one mining ship and a simple goal: remove the entire asteroid, uncovering resources and hidden finds as you work.

Dismantle asteroids

Cut into each asteroid’s surface, carve away sections and expose valuable deposits. Haul ore to your space silo and turn extracted resources into upgrades. As you mine, the remaining mass steadily falls from 100% to 0%; completing the job means leaving nothing behind.

Grow your operation

Improve your mining tools, ship capabilities and extraction efficiency to work faster and haul more. You can deploy mining and collection drones, assign them to an asteroid and set their priorities. Unlock surface drilling rigs to excavate alongside you, while automation reduces repetitive tasks and increases output.

Explore and research

Explore procedurally generated asteroid fields, scan your surroundings and search beneath the surface for buried artifacts and valuable deposits. Survey rewards and discoveries can be used for research into improved scanners and new equipment. Excavations can also bring dangerous encounters.

Take on contracts

Complete contracts to face new challenges and expand your industrial capabilities. Each improvement helps you dismantle the next asteroid faster; once one is reduced to zero mass, you can move on to a larger one.
