MAP31: Wolfenstein (Doom II)

MAP31: Wolfenstein is the first secret map of Doom II and can be accessed via MAP15. It was designed by Sandy Petersen and uses the music track "Evil Incarnate".

Walkthrough
As the secret levels are based on levels from Wolfenstein 3D (specifically, Floors 1 and 9 of "Escape from Wolfenstein"), the layout is fairly straightforward. From the start, go through the door ahead of you. Turn left and go through the door at the end of this hall (A). Continue through one last blue hallway and you'll arrive in a large grey room (B). Go through the door across from you once again. Proceed through the wooden hallway and through the door at its end. In the large wooden room, turn left, head through the door, around the bend in the next hall, and through another door. From the stone room, continue due south through another trio of doors (C). You will now come to an intersection; go left again.

Once in the final room, you can either flip the exit switch in front of you, which takes you to MAP16: Suburbs (D), or see secrets #2-4 for instructions to the super-secret level, MAP32: Grosse.

For those familiar with Floor 1 of the shareware version of Wolfenstein 3D, each brown-uniformed guard that appears in the "I am Death Incarnate" skill level are replaced by SS guards (1 in "I'm to young to die"/"Hey, not too rough", 2 in "Hurt me plenty" and 4 in "Ultra-violence"/"Nightmare") and the dogs are replaced by Demons. In addition, the hallways appear larger and the guards smaller than in Wolfenstein 3D.

Secrets
Before listing the official secrets, there are a pair of hidden areas present in the original Wolfenstein game that do not count towards Doom's secret tally. In the first wooden hallway, the back wall of the western alcove opens. The painting of Hitler in the stone room in the northwest corner of the map opens.
 * 1) At the east end of the map is a blue, t-shaped hallway. Take the door at the south end of this hall into a room with several alcoves in the walls. The back wall of the southeastern-most alcove opens, revealing a decidedly non-Wolfenstein secret area containing a BFG9000, a megasphere, a super shotgun, and several backpacks (E).
 * 2) In the room with the exit elevator, rather than flipping the end switch, open the southwestern corner of the room to reveal a secret area with a medikit (F).
 * 3) Secret exit: Open the western wall in secret 2 for a soul sphere to reveal the secret exit elevator.
 * 4) Before hitting the secret end switch, open the southern wall of this last area to reveal a soul sphere (G).

Bugs

 * Two demons in sector #41 (on ultra-violence or nightmare) occupy the same location, and are immobile until one is killed.
 * One Wolfenstein SS in the northern-most alcove sector #51 is flagged as deaf, while his 3 companions are not.
