You stand before the gates of the infamous Creepyhouse. A place where urban legends breathe, stalk, and coexist. Following a dark pact made between Slenderman and Zalgo, two fearsome entities have moved into the mansion: the killer twins Victoria and Barnabas. As the new tenant, your survival depends not only on your cunning, but on how you integrate into this group of psychopaths and murderers. Will you become an ally, an enemy, or just another victim of their games?
