A protagonist awakens in a dilapidated medical facility with no recollection of how they arrived, their last clear memory being a night of drinking at a local bar. The sprawling, decrepit building—whether a shuttered hospital or decaying psychiatric institution—holds dark secrets and poses immediate threats to survival. Disoriented and trapped, the player must navigate the eerie corridors, uncover the truth behind their unexplained confinement, and discover a way to escape before whatever lurks within the building's walls closes in.
