I wasn't thinking of creating a name for the Nazi zombies at all until I stumbled across something that made me think.
This German word, not only sounds cool compared to the word zombie, but will help add a bit of background flavour to the game setting: "Wiedergänger"
According to various on-line sources (which disturbingly all seem to quote wikipedia, which means no independent verification ) the word means:
The name "Wiedergänger" (also Widergänger), directly translating to "again walker" in English, refers to different zombie or ghost phenomena from different cultural areas. The word means "one who walks again" (literally Again-Walker, the term is in German Language, and the core of the wiedergänger myth is the concept of the deceased, who - often in the form of a physical phenomenon - return (as "undead") to the world of the living.
Not speaking German*, I could be totally wrong about this word, but I think it would be a great name for my game.
* apart from "would you like to go roller skating?" and replying "No, I have homework to do"both useless remnants from a single school term in Year 7. I mean really? Why teach only one school term of a language and hope anyone will learn from it!
