Step into a relentless nightmare inside Black Iron Prison, a maximum-security facility located on Jupiter’s dead moon, Callisto. In this collapsing, hostile environment, order has vanished and something grotesque is turning inmates into twisted, violent monstrosities. You are Jacob Lee, trapped in the middle of this disaster, forced to fight for survival while uncovering the disturbing truth behind the outbreak.
Every corridor feels claustrophobic, every sound echoes with danger, and every encounter pushes your nerves to the edge. Callisto isn’t just trying to kill you — it’s trying to break you. With cinematic storytelling, brutal horror and tension that never lets up, each moment feels raw, close and terrifyingly intimate.
Combat is intense and grounded, combining precise shooting, strategic dismemberment and a melee system that keeps enemies dangerously close. The oppressive lighting, industrial soundscape and cold metallic corridors turn the entire prison into a deadly trap. Surviving isn’t just about skill — it’s about staying calm when everything around you screams that you shouldn’t.
