Okay, the Wolfenstein and Commander Keen Stuff is from Doom II. The two levels (31 and 32) were secret levels that could only be accessed via a secret exit in level 15. THey were not designed for GBD2, and that is why they are so screwed up. The game's been modified so much that things don't work right.

ID made wolfenstien and doom, nearest I can figure they put it in there for a secret bonus level or something too that sort, possibly too show how “3d” gaming started back in the day. the stage with all the guys in it, nearest I can figure for gbdoom it's some sort of containment unit level.
