Damned sounds like every second horror movie you've ever seen. Only instead of helplessly watching the four people trapped in the haunted house get eaten/torn/slashed to death, you can take control and try and get them out.
Or take control of the monster trying to kill them. Either or!
The developers call it a "randomized online horror game", because instead of just having to get out through the same exit, levels will be objective-based, and these will change every time you play.
What sounds really cool, though, is the stuff you can do while playing the monster. Instead of just hunting the humans, you can also turn invisible and "haunt" them, triggering spectral effects and creepy sounds designed to scare them and throw them off their goal.
