And get it for free.
Bethesda announced today that they will be holding a closed beta on Xbox 360 for their upcoming Dawnguard DLC for Skyrim.
To apply for the beta you will need an account on their official forums, and can sign-up here. They will select the lucky participants, who get the full DLC (achievements and all) for free, next week. Not too bad if you get picked since the DLC will cost you 1600 MS Points ($19.99) otherwise.
I can’t think of any other single player DLC on the Xbox 360 that has had a beta, and the fact that this is the full version and free, is pretty awesome.
