So I assume everyone has seen the map from the end night mini games.
I have a theory that the map is a place we have never seen before. If you notice there are so differences from this and the map in the original fnaf. For example there is no supply closet. There is also no kitchen unless it is behind one of the boarded up doors. Furthermore the fact that we never see these rooms in fnaf1 helps prove my theory. Security cameras would have showed these rooms.
