Mass Effect 3 will soon be receiving a new single player DLC in the form of Leviathan. This DLC seeks to explore the origin of the Reapers, the massive sentient machines bent on destroying or subjugating all life, and it is up to Shepard to find "the most closely guarded secret in the galaxy." The Reapers are also looking for this Leviathan and wish to silence it forever, so Shepard and the crew of the Normandy must find it first. The events of the Leviathan DLC take place during the story of Mass Effect 3, so you may need to get a new character going. The DLC takes players to the darkest corners of the galaxy while unraveling the mystery behind the Leviathan, which is said to be capable of destroying Reapers. You will be able to explore uncharted worlds, new parts of the Citadel, meet new characters, and unlock a couple of weapons along the way.
The Leviathan DLC for Mass Effect 3 will arrive later this summer for $10. It will be available on the PC, PS3, and 360. There is also a new Firefight single player weapons pack arriving on August 7, which adds two powerful new weapons and five bonus weapons to the campaign.
