Hypothetical - Multiplayer Horror

[Zaffre]

I think it could work but not in the conventional sense. What I'm thinking is along the lines of Journey. You know they are there but you can't see them or what they do. Some things from their environments carry over to yours and vice versa. For instance, you could go into the Storage. Five minutes later someone else does. There is a closed door as you pass it. After the next player searches the room and finds nothing he leaves the door open as a potential hiding spot. You then go back to the room and find the door wide open and every container inside searched.
