First there is no Hitler zombie, and second there are no last levels for zombies mode
corps and life
life+corps
nothing does that's the last level in the game
No, it does not because I've beat the campaign on hard and there were no zombies.
Brigade is the lowest field command level.
The Last level of Zombies is Moon on the Retribution DLC which also includes the WAW map Packs redesigned for Black Ops and those could also be considered the last levels since most people without the hardened editions have not played the Black Ops Maps and some of them are Nazi Zombie maps.Rezurrection will include a new Zombie Map called Moon and a new zombie featured in the Moon Map Phasing Zombies. It will also include the 4 WAW Zombie Maps Nacht der Untoten, Verrückt, Shi No Numa, & Der Riese that have been modified for Black Ops.
