Today, Bioware released an all-new trailer for their upcoming Leviathan DLC for Mass Effect 3. The content is expected to expand upon the origin of the reapers, as well as add more single player gameplay to the overall campaign. Here is a brief description of the material from Bioware:
Mass Effect 3: Leviathan expands upon the events of Mass Effect 3, with gripping and emotional storytelling, compelling new characters, and powerful weapons and upgrades. Discover more about the origins of the Reapers as you race across the galaxy to find the Leviathan. Travel to new systems, wield the AT-12 Raider Shotgun and M-55 Argus Assault Rifle, and unravel the dark history of the Reaper Race before it is too late.
Mass Effect 3: Leviathan will hit Xbox Live, PSN, and PC on August 28th in North America and August 29th in Europe. No price point has been confirmed yet, but it would be safe to assume that anything around 10 bucks or under will be the safest bet.
