Pimpenstein was the name of a project by DJ Blazkowicz. It was mentioned in passing in a DHW thread dated April 2008, long after DJ Blazkowicz had left the community. Blazkowicz stated:
My add-on "Pimpenstein" was in the works. It had a politically-incorrect storyline and some basic coding changes. We were very secretive about the contents of the add-on because nothing, up to that point, had taken the direction we had. I ran into some graphical problems one time after compiling the code, and my interest waned after the club was neutered. It was never finished.
