How to Enter the Secret Wolfenstein 3D Level:
Starting at Chapter 4, after meeting Anya in the ratty secret base,
go upstairs and look for a room with an old mattress on the floor near
the window. It's all the way up on the third floor, through a small
workshop with an infinite supply of throwing knives. Interact with the bed,
and you'll have to relive your "nightmare" - BJ teleports to his original
adventure in Wolfenstein 3D, complete with 2D enemy sprites and flat corridors.
