Build your industrial space station and become an idle miner tycoon in a deep-space economy. Lay out your colony smartly: link ships that mine asteronium to factories that refine it, then route goods to trade drones — every connection matters, every bottleneck is yours to solve. Expand around the asteroid, upgrade your modules, and keep production flowing even while you’re offline. Research new technologies, earn permanent boosts between runs, and push your throughput to the limit. Balance mining speed against asteroid stability, then launch to Earth to refine rare finds and come back stronger. Watch your numbers soar, your layouts evolve — and chase the rumor of a mysterious element hidden at the cores of the largest asteroids. Should we explore?
