FNAF stands for Five Nights at Freddy Fazbear (or XD). It's 1 chapter. it was the halloween floor but it became regular floor. Number floor is 44. this floor looks almost exactly like regular FNAF. After While exploring the floor, you are teleported into the elevator and when you are teleported into the elevator the light goes out (like in fnaf when the battery runs out and you have a 50/50 chance of surviving, you will not survive) but in the elevator the light goes out for about 10 seconds after which Freddy Fazbear attacks you. if you are close to him he will eat you while screaming. if he didn't eat you, you stay in the elevator and look at the people who died from him...
