A listing has emerged on Amazon that points to the inclusion of a zombie oriented campaign in Black Ops II.
While zombies have frequently appeared in Call of Duty games, they've only been a part of multiplayer modes.
But that may be changing, as Kotaku has found, with Amazon's 'Key Game Features' noting "the inclusion of zombies in gameplay, both as an option in multiplayer and as a campaign option."
Might be a mistake, but we'll keep you posted.
