HalfSkull

Mechanic
An image of him will appear at random on your camera feed during the night. Switching cameras will only keep him on your screen, so you'll need to flip down the camera to get rid of him. If you fail to do so in time, he'll shut down the camera he's on and all its features.

Trivia

 * Halfskull was the only character from Demo 1 to not make it into Demo 2, however, he returned as a DLC.
