Activision confirms that Call of Duty: Black Ops 2 will include a reminagined Nuketown 2025 multiplayer as a downloadable bonus for those who pick up a launch copy of the game. A brief FAQ on the game's official site reveals that the map download will be available when the game launches on November 13, 2012.
This confirms a recent rumor that the re-tooled map from 2010's Black Ops would be returning for the sequel, a rumor that started when a tipster photo from a retailer apparently outed Nuketown 2025 as a pre-order bonus. The offer applies to all platforms. Those who miss it will presumably be able to buy Nuketown 2025 separately, though the FAQ makes no mention of this one way or the other.
