Seeing Immoral Cumbat is also featured on this game, perhaps this title is worth mentioning too.
Nestlesux noticed an auction on eBay, offering Duke Screw'Em 38D as part of a set of 3 games. Unfortunately, the auction for this Duke parody ended.

Graphics look much lamer than the Duke Nukem 3D Build engine would be capable of though, so I don't think it was created from a Duke TC...
