In just under three weeks, The Elder Scrolls V: Skyrim will birth the first of its many expected expansions, the vampire saga Dawnguard.

Due June 26, the Dawnguard DLC is expected to provide ten to 20 hours of new content, and will add two new factions, new items, and new weapons – most notably the crossbow – to the popular RPG.

The Xbox 360 has 30 days of platform exclusivity with Dawnguard, before it is released on PC and PlayStation 3.
