Grimstar, the real-time strategy game about corporate servitude, planetary exploitation, and personal loss, launches today exclusively on Steam. Developed by Sven Rahn Games, Grimstar combines a dark science fiction narrative with classic RTS mechanics and a progression system that rewards ruthless efficiency.

In a future where Earth’s energy reserves are exhausted, a powerful corporation turns to the planet Grimstar—rich in alien crystals and teeming with hostile life. After the sudden death of your brother during a mission, company law demands that you fulfill the remainder of his contract. What begins as forced labor becomes a journey into a planetary mystery—and a fight for something more than just survival.
