Dupe is a recurring entity in The Lost Floors.
Appearance
Dupe appears as a white face with a large, toothy smile with bloody teeth and a pair of red bloodshot eyes, everything other than its arms and face are cloaked by the darkness of the room it inhabits. Both its smile and eyes glow in the dark. Most of its face is covered in red details, similar to blood.
Behavior
Dupe has a chance to spawn false doors marked with incorrect numbers in rooms with multiple possible doorways. Dupe emits a quiet rumbling noise that can be heard when standing close to it.
After a certain amount of time after a player opens a new door, Dupe will scramble the numbers of all previous doors, rendering them unreadable. As players progress, Dupe will give less time before scrambling numbers.
If a player attempts to enter a Dupe door, the door will open, and Dupe will quickly lean its head forward, grab the player, bite them, throw them onto the floor and slam the door shut, dealing damage. In 3rd person, this process appears as Dupe pulling the player close to it, emitting red smoke, throwing the player onto the ground, and then slamming the door. If the lost damage is enough to kill a player, Dupe will, in 3rd person, grab the player and pull them upwards, then slam the door. After Dupe has attacked a player, the number plate on the door will become blurred and unreadable.
Dupe can be crucified by the Crucifix.
