Are you kidding me? Zombies MADE Black Ops. Without it, the game likely wouldn't have continued to sell well. The Rezzurection map pack was more popular than any CoD map pack before, and I wouldn't be suprised if it sold more than the other three map packs COMBINED. You really don't know a thing about zombies and its history, do you?
