The first downloadable content for Call of Duty: Black Ops - just announced as the UK's Christmas number one title - will be released for the Xbox 360 on 1 February 2011 at a price of $15, according to Xbox Live director of programming Larry "Major Nelson" Hryb.
Speaking in his most recent podcast, Hryb described the download as a multiplayer map pack, with four normal multiplayer maps and an additional stage for the game's co-operative Zombies mode.
Two of the standard multiplayer maps will be based on locations from the single-player campaign: Hong Kong and the Arctic Circle. The other two will be all new locations; one based around the Berlin Wall and the other an ice hockey stadium - the latter apparently a reference to the ice hockey semi-final between the U.S. and USSR during the 1980 Winter Olympics.
Microsoft has an agreement lasting till 2012, that will see all downloadable content for Black Ops released first on Xbox 360. Traditionally the downloads for Call Of Duty have been limited purely to additional multiplayer map packs, but Activision has hinted that the extras for Black Ops may include more varied content.
Although the point has never been clarified it is assumed that the same downloadable content will also be released for the PlayStation 3 and PC versions of the game, likely around a month after the Xbox 360.
