The eagle-eyed team at CVG has confirmed the inclusion of a Nazi Zombie mode in Call of Duty: Black Ops after receiving an announcement about the game's official strategy guide.

Reportedly, the BradyGames guide features "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".

First introduced in Call of Duty: World at War, the addictive Nazi Zombies mode sees a team of up to four players cooperatively battling waves of Nazi Zombies while attempting to barricade their stronghold to stem the flow of enemies.

Following this presumed blunder that has pre-empted any official announcement from Activision, the official Black Ops site now consists of a flash animation featuring none other than Nazi Zombies.
