"4th Reich: Puremen vs. the Mutants for Control of the World" is a somewhat obscure wargame by Task Force Games based on (albeit without attribution) the SF-novel "The Iron Dream" by the Jewish author Norman Spinrad. This very controversial novel describes a parallel world in which Hitler wasn't successful with his "Kampf" in Germany and became a successful SF-pulp-novelist in the US. " The idea of Spinrad's novel was to expose fascist tendencies in 50's American literature.
The TFG designers transported this "theme" into a board game which plays like a wargame: future Nazis against future mutants. The names of all protagonists have been changed in an apparent attempt to avoid infringement, but the game clearly takes its slightly tongue-in-cheek approach directly from the book.
