The Dawngaurd DLC for The Elder Scrolls: Skyrim will be availiable on the Xbox Live Marketplace tomorrow (June 26th), and will cost you 1600 MS points (or $20).

There is no word yet on when the DLC will be available for the PC and PS3.

Word is that the Dawngaurd DLC will have 15 to 20 hours of fresh gameplay in which you can join up with the Vampire Lord Harkon and destroy the Sun, allowing you to become a Vampire Lord yourself – or join up with the Dawngaurd and oppose him.

So 360 owners, get your game on tomorrow with Dawngaurd!
