It has been confirmed that this game will feature a Nazi Zombie mode. You reprise your role as Dempsey, Nikolai, Takeo or Richtofen. The way that they work into the more modernized weaponry is that Richtofen had created a time machine, thus sending the four WW2 era characters along with Nazi zombies through the time portal. It has also been announced there will be a DLC included with the Hardened and Prestige editions of the game (And likely later available as a purchase DLC for those who buy the standard version) of the original four Nazi Zombie maps; Nacht Der Untoten, Verrückt , Shi No Numa and Der Riese. They will be updated with the graphics, game-play physics, etc. for Black-Ops. Also, the four playable characters will be available in both Nacht Der Untoten and Verrückt [as they originally only appeared in the last two]. But the best part, Black-Ops weapons will be available from the Mystery Box!
