i doubt it. this is cold war era, so germany is not really involved. besides, if there was some kind of nazi/horde mode, than it wouldnt be nazi zombies, because that would have nothing to do with the game.
hope this helps\

There never was any Call of Duty that had NOTHING to do with germany. A Mp5 prototype ingame is pretty much confirmed its a german weapon end of discussion on that one. And about everything else I've already written. Do never say germanys not involved because youre trying to piss on the countrys land that has the best weapon engineers, which the makers of the CoD series obviously get, no wonder german weapons were always the best in the games. Remember MW - Mp5, WaW - Mp40, MW2 - UMP45?
But yeah here your +rep cookie *throws a rep*
