About Cosmic Miners
Cosmic Miners is a single-player sci-fi game about mining, exploration and ship upgrades. You play as a Harvester, extracting resources from asteroid belts and planetary orbits, building your fleet and pursuing a place in a galaxy shaped by rival factions and a galactic economy.
Mining and exploration
You travel through diverse asteroid fields in search of rare ores and other resources. Upgradable ship modules let you adapt your mining systems, while advanced tiers open access to high-value materials hidden behind tougher asteroids.
Stations serve as hubs where you can supply resources, upgrade your ship, recruit crew members and interact with leaders and the local community. Each station has its own role in the galactic economy and its own secrets.
Factions and missions
The galaxy’s factions are Pirates, Drifters, Harvesters, Capitalists, Technocrats, Leviathans and Proxies. Each offers exclusive missions, rewards and opportunities to shape your reputation and future. You can remain with the Harvesters, your starting faction, or try to rise through the ranks of the Leviathans or join the Pirates.
Main story missions reveal mysteries surrounding the factions, ancient relics and the forces behind the interstellar economy. Hidden lore is scattered across the stars, and your choices shape your legacy.
Ships and crew
You can equip your ship with over 20 modular systems, including mining lasers, cargo holds, shields and weaponry. Hire and manage up to five specialized crew members, each with skills that improve mining, combat or trading.
Pirate factions and rival miners can threaten your ship. Tactical space combat puts your upgrades and decisions to the test as you defend yourself against them.
