I'm sure you vividly remember the map Nuketown from the original Black Ops. You know, the only map that people ever wanted to play. It was so popular that Treyarch even made a 24/7 Nuketown playlist for it. If you're looking forward to Black Ops 2, you'll be happy to know that Nuketown is making a return to that game, but will be updated and re-imagined for the new Black Ops 2 setting.
Keep in mind, that this won't be for everyone. The additional map will only be available to those who pre-order Black Ops 2 at participating retailers. The list of retailers haven't been released but you can assume that GameStop, BestBuy,, GAME, and Amazon will make the list among others.
Call of Duty: Black Ops 2 is set to release on November 13th.
