Hitler's Revenge is a mod for shareware Wolfenstein, made by Glen Meux. Maps date from late 1997 and graphics from August 2001, but seemingly the set was not uploaded on any known site at either time.
One of the reasons for this could be its shared title with an older, widespread mod.
It was found by Colonel Bill and included in an archive collecting mods found on Brian Lowe's yellow site, suggesting it might have been uploaded but fell by the wayside.
