Mass Effect 3 Leviathan DLC releases August 28

Commander Shepard's intricate tale will get another wrinkle on August 28 when the Mass Effect 3 Leviathan downloadable content goes on sale. BioWare revealed the release date for the DLC today across the PC, Xbox 360, and PlayStation 3, though European PS3 owners will need to wait until August 29 for it to appear on PlayStation Network.

Leviathan's new missions unfold roughly in the middle of the game and see Shepard chasing clues to the existence of a mythical reaper-killing creature, as seen in the GameSpot preview viewable below. The events that unfold thereafter will have an impact on the Extended Cut versions of the game's controversial endings.

The DLC will cost $10 (800 Microsoft points) and is the third to add on to the events of the single-player game, after the day-one release From Ashes and June's Extended Cut.
