Bethesda has unveiled the first DLC for The Elder Scrolls V: Skyrim.

Dawnguard is an additional campaign where players will have the choice of joining either the vampiric forces, or joining the heroes of the Dawnguard as they look to hold back such devilishness – specifically by stopping the blood suckers from destroying the sun itself.

Glean what else you can from the trailer and look out for updates on the downloadable content throughout next week’s E3 show where we’re promised more details will be forthcoming.
