The much-loved feature Treyarch introduced in Call of Duty: World at War, Nazi Zombies, will make a full return in Call of Duty: Black Ops, it seems, after CVG had a look at the game's official BradyGames Game Guide which boasts: "A complete walkthrough to the gritty Cold War-era Campaign mode, tips and tricks to rank up in Multiplayer, how to excel in Co-Op, or fight back the relentless Nazi Zombie horde".

Further to this new-found proof of the existence of zombies, Treyrch uber-boss, Mark Lamia, in an interview with Edge Magazine explained that Treyarch have been listening closely to the core community when it comes to war zombies.

"We continued to evolve [Nazi Zombies] after World At War," he said. "There was a dialogue going on with some of our hardcore community, and we were able to interact with the community and evolve - we did that with our zombie lore."

All of this seems to coincide with what's going on over here.
