Zombies Invade Nuketown
More Call of Duty: Black Ops II action from the Nuketown Zombies Bonus Map which can’t be found on Xbox Live unless you’re a Season Pass holder, it should have automatically downloaded when you started up the game.
As well as the map, you get an exclusive in-game calling card. The Nuketown Zombie Map is a bonus which is only available if you have the Season Pass, you can’t buy it separately, at least not yet anyway.
If you have a spare 4000 Microsoft Points, that’s just enough to get the Call of Duty: Black Ops II Season Pass and apparently, you actually save money compare to if you bought the map packs on their own, which you can’t do, so you have to buy the Season Pass.
