So far, the vast majority of Mass Effect 3 downloadable content has been for the multiplayer. But in a primarily single-player game, it only makes sense that BioWare had plans to produce new story content too. That may have been put to the side to focus on the recently released Extended Cut ending, but now that it's out of the way fans seem to have uncovered plans for a new story mission. Spoilers follow.

A partial script was uncovered in the Extended Cut download, by a user on the BioWare forums (via Eurogamer). The rumored content is called "Leviathan," and has Shepard rescuing a scientist named Ann Brynson from a mining facility. The facility is controlled by a Reaper named Leviathan, a defector from the Reaper group who killed one of its own kind. It also mentions the Reapers' creators, a clear call-back to the ending. Shepard's actions can save Brynson's life, and seemingly bring Leviathan to join in the fight against the Reapers as a War Asset.

The name "Leviathan" has come up as a presumably derelict ship in the first Mass Effect, and then was said to be inadvertently reactivated by batarians. You know those batarians, always reawakening sentient killer spaceships.

As Eurogamer points out, producer Mike Gamble hinted at more DLC to come last night with a tweet that read, "As i've said before,we do this for you! EC was our gift to the fans.Hope you enjoyed. Also...keep your ears open over the next little while."

An EA representative told Shacknews, "We don't comment on rumors or speculation."
