you and all class 1A got stuck in a long entity filled hotel. but since you all are human after all there are rooms with beds throughout the map for you to sleep or hide under. closets can be also used for your advantage to hide from entities like Rush and Ambush. drawers have gold in them so make sure to pick them up for Jeff's shop after door 50. Each room has another door behind it like a loop. It goes up to 100. Boss battles is on door 50 and 100.
