The Reanimated

The Reanimated are a pair of humanoid Monsters kept in the Facility. They are listed on the Whiteboard and are bet on by the Administration department. They can be spotted during the film and System Purge.

Physical Descriptions and Attributes
The Reanimated are depicted as living corpses similar to zombies, but as their name implies, their undead state comes from deliberate reanimation of dead tissue, possibly by mad science or black magic, rather than a zombie virus or radiation. Their bodies are crudely stitched together and their faces are attached upside-down to their heads, causing them to breathe rapidly in a hushed, hoarse tone. Their most notable trait is the ability to quickly climb up walls and across ceilings with ease. They are similar to the Deadites and the Reaver. Both of the Reanimated appear as a pair of (formerly) male humans, and there is no knowledge of their past lives or how they met their current fate.

It is unknown what item summons them. Possibilities include occult objects related to death and resurrection, voodoo dolls, books of magic, or possessions belonging to the deceased from which they were created.

Appearances
The first time we see the Reanimated is in their Cube Prison on a CCTV camera, when Dana and Marty are hiding in the Elevator Lobby's Control Room. The second time, only one of them is seen, and it is when the film is switching between camera monitors to show monsters during the carnage of the Purge. Here one of the Reanimated is crawling on a wall or ceiling and gets up close to the camera before it switches out.

The Reanimated are also seen in the behind the scenes footage.

Inspiration
Their name is a clear tribute to H. P. Lovecraft horror story and its subsequent film adaptation The Re-Animator and its sequels. Their appearance and behavior, on the other hand, is almost identical to the Spider Shibito from Siren and the possessed Regan Mcneil and Emily Rose, down to their seeming lack of eyesight. The game drew on other Lovecraft stories, mainly Shadow Over Innsmouth.

This creature is also reminiscent of the strange visions that appear in the nightmare sequence in the film Jacob's Ladder when Tim Robbins' character is having hallucinations as he is being wheeled through the corridors of the mental hospital.
