As promised, EA has revealed the first details about Mass Effect 3’s first full DLC expansion pack. Dubbed Leviathan, the single-player add-on promises to expand upon the events of the main campaign with “gripping and emotional storytelling, compelling new characters, powerful weapons and unique upgrades”.

By playing the DLC, you’ll be able to learn “more about the origins of the Reapers as they race across the galaxy to unravel the mystery that surrounds the fabled Leviathan”. The content’s due out this summer on PlayStation 3.

Update: We've included the expansion pack's first trailer below. Aren't we lovely?
