The first Call of Duty: Black Ops downloadable content is to hit the Xbox 360, a month before it lands on the PS3.

The map expansion pack will cost you 1000 Microsoft Points, which is £8.50 in real money.

The news was broken by Mr Xbox LIVE himself, Larry "Major Nelson" Hryb, who stated on his podcast that the DLC would be a multiplayer map pack, with four normal maps and a Zombie co-op option too.

Black Op gamers will be transported to locations from the single player Hong Kong and the Arctic Circle maps as well as two brand new locations. One of these will be based around the Berlin Wall, and one will be an ice hockey stadium that pays homage to the 1980 Winter Olympics.

Microsoft has a deal to get all Black Ops DLC first that runs until 2012. It's not confirmed, but it's likely that other formats will get the expansion in March 2011.
