In Mass Effect 3, an ancient alien race known only as “Reapers”, has launched an all-out invasion of the galaxy, leaving nothing but a trail of destruction in their wake. Earth has been taken, the galaxy is on the verge of total annihilation, and you are the only one who can stop them. The price of failure is extinction. You, as Commander Shepard, must lead the counter assault to take it back. Only you can determine how events will play out, which planets you will save from annihilation and which alliances you will form or abandon as you rally the forces of the galaxy to eliminate the Reaper threat once and for all.

The Mass Effect 3: Resurgence Pack adds two new maps to the game’s cooperative multiplayer experience, along with a variety of new playable characters, new weapons and new items that can be unlocked by acquiring reinforcement packs in the game’s multiplayer store. The Mass Effect 3: Resurgence Pack will be available for download on April 10 on Xbox Live and the Origin client software and on PlayStation Network in North America on April 10 and in Europe on April 11.

The Mass Effect 3: Resurgence Pack includes the following content:

• Two New Action-Packed Maps – Take the battle to Firebase Condor, a warzone outpost located on one of Palaven's moons and Firebase Hydra, an old abandoned quarian colony which has since been converted into a critical power facility.

As part of the Mass Effect 3 Galaxy at War system, success in  the cooperative  multiplayer experience in Mass Effect 3 links back to the player’s single-player campaign, helping Commander Shepard rally the forces of the galaxy to eliminate the Reaper threat once and for all.  Multiplayer puts players in the role of a team of elite Special Forces soldiers sent to protect resources and assets that can help the greater war effort.

Mass Effect 3 on the Xbox 360 includes support of Kinect, allowing players to immerse themselves into the Mass Effect universe even further through new voice recognition technology.
