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.

Battle with your comrades or even your own friends in this all-out galactic war to take Earth back. With co-op online multiplayer missions new to the Mass Effect universe , you can choose from a variety of classes and races, form an elite Special Forces squad, and combine weapons, powers and abilities to devastating effect as you all fight together to liberate key territories from enemy control in this third entry of the epic intergalactic RPG franchise.
