Call of Duty: Black Ops 2. IGN posted an image of a poster supposedly from GameStop; another image from GAME shows the same pre-order bonus. Nuketown 2025 is apparently a remodeled version of the popular Black Ops map, Nuketown.
Each image suggests there will be a "limited edition pack" of Black Ops 2, which we assume is akin to the first pressing limited edition runs we've seen for games like Need for Speed: Hot Pursuit and Twisted Metal. We've inquired with Activision and will update accordingly.
