Call Of Duty: Black Ops II To Feature Zombie Campaign?

Did Amazon just slip a little nugget of info by when no one was looking? According to their listing for the game, there will be an option for zombies in the campaign. Check it out by clicking the link or by looking here:

So what exactly does “as a campaign option” mean? My interpretation is that there could be a way to zombify the actual campaign so that you are going up against zombies instead of the normal antagonists. Or of course, there may just be a separate campaign mode for zombies this time around. In any event, I don’t believe this information has been divulged by Treyarch themselves, so I am sure more details will follow. Call Of Duty: Black Ops II is in stores November 13th for the Xbox 360, Playstation 3 and PC and on the November 18th launch of the Wii U.
