First Skyrim DLC Titled Dawnguard, Coming This SummerNews
Skyrim‘s first piece of downloadable content, Dawnguard, will be out this summer for Xbox 360. More information will be available at E3 but we can speculate that this DLC may involve the “Order of the Mythic Dawn”. There is also no word on a PC or PS3 release yet; however the original agreement specified a 30-day exclusivity window for Microsoft.
