Before the signal was lost the last voice heard from the Hazmat team's radio was "unidentified entity." You need to create a new team to find out what's going on inside the Backrooms.
This game is played as a team with one Backrooms Entity (Killer) player selected from a maximum of five people. There is only a multiplayer co-op mode. If you have friends, this is great. Otherwise, you can join the server lobbies.
