It's a 130 MB download for the Free DLC Map Free Fall and it's mandatory in order to play online multiplayer. All I can say is that it's about time that Treyarch and Nintendo got their acts together. For a VERY long time, the Nintendo versions of Call of Duty titles have been absent of downloadable content and maps from Treyarch/Infinity Ward/Activision. Now players can breathe a small sigh of relief that they'll be able to at least try one of these nearly exclusive stages. Hopefully, this will be a stepping stone towards future third party support and integration. Nintendo desperately needs all the help it can get right now.
