|Part of||Episode 5|
Episode 5, Floor 7 is the seventh level of Wolfenstein 3D episode "Trail of the Madman". The trickiest part of this level is that enemies can almost always come through more than one door into your room.
Don't miss a machine gun behind you at the start. Otherwise head forward into the open area then retreat and clear the enemies. Emerge into the + shaped room, head left, and then left again as soon as possible. Open either of the two doors to the right which will both connect to a room with many enemies and the gold key. Re-emerge into the + shaped room, and turn left. Go straight for as far as possible, then turn right for the gold door. Any of the three doors in the blue stone area beyond lead to the room with the silver key and many additional enemies. Return outside the gold door, back into the + shaped room, and turn left. Turn left again as soon as possible, then when you reach the wall head into the door on the right. All the doors on the far side of this red brick room lead to the same room, and many or all will open with SS officers when you fire a shot so be prepared. Head through any of these many doors, and you'll find the silver door. From there it is one more heavily guarded brown corridor between you and the exit.
