You wake up in an unknown, shifting location alongside your girlfriend, Stracy. The relief of finding a familiar face doesn't last—you soon realize you are trapped deep within the infinite yellow complex, a boundaryless black-site constructed by the government to secretly imprison prehistoric specimens and unidentified hybrid monstrosities away from the public eye.

Here, reality itself is compromised. Walls, floors, and doorways destabilize without warning. Touching affected surfaces risks catastrophic glitches beyond marked sectors, and anyone lost to the void is officially declared unrecoverable.

Containment has completely collapsed. Violent hybrid apex predators and prehistoric beasts now stalk the endless carpeted halls. Left alone in a rapidly deteriorating facility, you must navigate the unstable corridors, scavenge key artifacts, bypass locked security sectors, and find an extraction point before you are hunted down.
