Call of Duty: Black Ops Official site (First Strike)

The first downloadable content for Call of Duty: Black Ops has just launched on Xbox LIVE!

If you're an Xbox LIVE gamer, then we sure hope you've taken the day off as today is the day that the Black Ops battlefield is freshened up!

Four new Multiplayer maps, a new Zombie level and four new achievements are now available! The First Strike Pack 1 has been released and it may take some time to appear for you.

There are a few ways in which you can find and download First Strike. If your account is over 18, you can download it on your region's official Xbox website so that it will automatically download once your console is switched on. To download it on your Xbox, visit the Games Marketplace tab on your Dashboard and then either search for Black Ops via titles A-Z, or click on Game Add-ons.

You can also insert your Black Ops disk, head to the main Multilplayer menu, click on Store and then download from the Map Pack section. Note that if you're on an Xbox LIVE application that uses your Internet connection, such as Sky Player, or you're simply playing multiplayer, the download will pause. So make sure that you're either playing Single Player games or taking a break when the Map Pack is downloading to ensure the quickest and smoothest download speed possible!

So what are you waiting for? Ascension, Berlin Wall, Kowloon, Discovery, Stadium and 150 Gamerscore is waiting for you now for 1200 Microsoft Points!

Stay tuned for details on some First Strike giveaways that we'll be holding VERY soon.
