Dawnguard, the first official add-on DLC for The Elder Scrolls V: Skyrim is coming to Xbox 360 this summer. The downloadable content will cost 1600 MS Points and will remain 360-exclusive for 30 days before making the leap to PS3 and PC. What's that? You want to see the trailer? Well, if you insist...
The trailer shows some beautifully gothic settings and creepy graveyards, crawling with all manner of supernatural creatures of the night. Best thing? Sounds like you'll actually get to be one of those creatures. With wings and everything. Alternatively, there's the eponymous Dawnguard, which will see you fight them off... and probably use their wings to decorate your house in Whiterun.
Needless to say, we're extremely excited about this - expect to see more of the add-on next week at E3.
