StarRupture is a first-person open-world survival base-building game developed and published by Creepy Jar — the Polish studio behind Green Hell — and one of Steam's most anticipated co-op releases of early 2026. Set on Arcadia-7, a hostile alien planet orbiting the volatile star Ruptura, you are a prisoner tasked with surviving an environment that constantly works against you: aggressive alien wildlife, dangerous meteorological events triggered by the volatile star itself, and the relentless pressure of resource scarcity on an alien world far from civilisation.

Key Features: • Open-world alien survival — Arcadia-7; hostile wildlife + volatile star Ruptura events • Base building + automation — construct industrial systems and production chains à la Satisfactory • 4 player co-op — Biologist, Scientist, Soldier, Engineer; each with unique specialisations • Dynamic planet — ever-changing world; heat waves + future frost disasters + meteor events
