Now, it relentlessly patrols the halls, hunting anyone who dares to enter.
Your goal is simple: escape with your life. Explore the mansion, solve mazes and puzzles, find the keys needed to progress, and use wardrobes to hide from the monster pursuing you. Every step brings you closer to the truth… or to your demise.
Will you survive the constant chase of Prototype C-23 and escape from Dr. Hoismer's mansion?
