EA and Bioware talked a lot of shop about Mass Effect 3 today, revealing and detailing two new DLC packs over the course of the discussion. Bioware's blog revealed new information regarding the Leviathan pack, which will further the game's single-player story.

"Something lurks in the dark corners of space, something powerful enough to kill a Reaper," Bioware stated. "Shepard must discover the most closely guarded secret in the galaxy before the Reapers silence it forever. Discover more about the origin of the Reapers as you race across the galaxy to find the Leviathan. Unravel the dark history of the Reaper Race before it's too late."

But wait, with an ending like Mass Effect 3's, how is there any room for DLC stories? Leviathan will apparently take place before the end of the game, casting players as Shepard in the midst of the main game's events. Players will be able to "explore uncharted systems and new areas on the Citadel," and "interact with all new characters." Finally, players will get the AT-Raider Shotgun and the M-55 Argus Assault Rifle. With the way that Mass Effect 3 ended, we hardly think there's much room for another Reaper-killing weapon in the galaxy, so we can't exactly see the Leviathan mission going swimmingly. We'll be able to say for certain in late summer, when Leviathan releases for ten bucks.

Firefight, on the other hand, will be a simple weapons pack consisting of seven new guns for the game's single-player campaign. It will launch on August 7th for two dollars.
