The astronomically huge and long awaited Grand Theft Auto IV expansion, The Lost and Damned, has just gone live on Xbox Live!

The DLC should already be appearing on the Games Marketplace to download for most 360 users. If it’s yet to appear in your region, fear not though!

You can access the download by going to Marketplace on Xbox.com, and buy it from there. You will then be able to download it by going to your Active Downloads on your 360 dashboard.

The Lost and Damned will set you back 1600 MS Point, and 1.78GB of your HDD, and has an estimated 10 – 15 hours of gameplay packed away in it. Considering the scope of this content, that’s a generous price.

Microsoft also added new “biker” related avatar clothing earlier to coincide with the launch of the 360 exclusive content. You’ll find a full list of the new clothing under the cut.
