EXTRACT
- Extract precious resources to craft new items. Each resource requires the proper tool to be mined. The better the tool, the faster the harvest. Upgrade your gear to reach the most valuable mineral of all: Silicium.
BUILD
- Build your base to secure your loot and defend against enemies. Level up to learn crafting recipes of items and structures.
EXPORT
- Launch transport rockets to export ores into space and get your paycheck. Craft smelting equipment to refine ores for higher value and improved efficiency.
EXPLORE
Explore the planet to scavenge resources. But beware, corrupted mining drones have turned hostile and attack without warning.
FIGHT
- Craft weapons and fight back to defend your base and clear abandoned mining outposts. Level up to unlock stronger weapons and defenses.
PLAY YOUR WAY
- Play solo, coop or compete in public PvP servers where the action never stops.
- In PVP, death means starting over, but your earnings unlock new blueprints for your next run. No persistent bases. No offline raids. Every session is a fresh battle for survival where only active players compete. Can you outsmart the competition and extract the most resources?
