After revealing Dawnguard was the title of Skyrim‘s first DLC Bethesda went on to say the first trailer would be shown at E3. Well, we got our gift a little early this time because this trailer just came out yesterday.
It appears as though Dawnguard is to be focused around vampires and those that fight them, known as the Dawnguard. Sounds like players will be able to play either side of the fight in both new and old locations. Expect plenty of new enemies and weapons including crossbows.
