"Nuketown 2025," a free downloadable map from Black Ops 2, has reached Nintendo's console a mere year and (not quite) nine months since the game's release. IGN reports that the map is included in the latest title update, as is an icon for the Zombies mode map, "Die Rise." It is noted, however, that although Die Rise appears on the game's menu, it is not playable.
As for Nuketown, well ... better late than never, Wii guess.
