The Elder Scrolls V: Skyrim's vampire-themed Dawnguard DLC is expected to launch in the last week of June.
Following an E3 showing, game director Todd Howard said (via Joystiq): "Tentatively, it's coming on June 26."
That's assuming there are no unforeseen problems, he added. Bethesda is running a Dawnguard beta to iron out any potential issues.
Dawnguard will be available to download for 1600 MS Points (£13.71). The first two DLC packs for Bethesda's sprawling RPG will be exclusive to Xbox 360 for 30 days from release.
