Mass Effect 3: Leviathan DLC Announced, Wii U Launch Title

During its summer showcase today, EA officially announced Mass Effect 3’s Leviathan downloadable content. According to EA, the content allows players to “discover more about the origins of the Reapers as they race across the galaxy to unravel the mystery that surrounds the fabled Leviathan.” It'll pack new planets and characters, but you'll still play as Commander Shepard.

Leviathan was originally revealed by leaked files extracted from the Extended Cut endings. Later, the content was confirmed by voice actor Anthony Skordi (who plays Leviathan). BioWare also hinted at new Mass Effect 3 content during Comic-Con, showing a teaser that included a red Atlas Mech underwater.
Specific details about Leviathan haven’t been announced, but we know it follows the search for Leviathan, a rogue reaper who has indoctrinated a mining colony. Look for it this summer on 360, PS3 and PC.
It was also revealed that Mass Effect 3 will be a launch title for the Wii U and pack a digital motion comic (similar to the Mass Effect 2 one for PS3) that allows Wii U players to make choices and build their Shepard's history.
