Voice actor Anthony Skordi has confirmed that the rumoured Mass Effect 3: Leviathan DLC found nestling among the code of the recently released Mass Effect 3: Extended Cut is indeed real, and will be the first dose of single-player story-based content for the game, following several free multiplayer add-on packs, including the upcoming Earth pack, due to release on July 17th.

SPOILERS AHEAD, so if you haven't played or finished Mass Effect 3 yet, or indeed you want to go into the DLC cold, look away now. Skordi will apparently voice the titular Reaper named Leviathan, with a story set prior to the ending of the game. One for the second Insanity playthrough perhaps? Leviathan is apparently a Reaper traitor, separated from his own kind after killing one of them.

Shepard runs into Leviathan during a mission to rescue a scientist named Ann Brynson, who's being held at a Reaper-indoctrinated mining facility controlled by the errant Reaper. It's thought that the Leviathan DLC will shed more light on the Reapers and their origins, while offering Leviathan himself as a potential War Asset or an ally.

Yet to be officially announced, it's entirely possible that a proper reveal for Mass Effect 3: Leviathan will be coming to Comic-Con in San Diego later this week alongside the ME3: Earth multiplayer pack, with more details hopefully forthcoming. Watch this space.
