From what I've seen, you have a bunch of people playing as survivors trying to escape and 1 monster who must kill them. All the survivors spawn in random rooms. Keys are hidden around the map that will open certain doors.
What seems fun is that a person can be stuck in an area with keys that don't open any of their doors, so they have to wait for someone else to get to them with the key that opens their door from the other side and let them out.
Also the person playing as the monster cannot see the players or doors until they spawn. Once they spawn, they stay spawned for maybe 10-20 seconds where they have to kill someone or disappear and wait to be able to respawn again. Players also have to make sure they don't alert the monster to their location (for example not saying they just heard a toilet flush, saying what room they're in, or heard a ghostly noise (which means the monster just passed through you))
