Mass Effect 3 plunges you into an all-out galactic war to take Earth back from a nearly unstoppable foe- an alien race known as Reapers. Groundbreaking interactive storytelling drives the heart-pounding action in which each decision you make could have devastating and deadly consequences. You are Commander Shepard, the only one who can save Earth from annihilation. But you are not alone. At your side is a team of battle-hardened soldiers ready for your command. Flank enemies with your squad or take them down lone wolf. Use cover or go in guns blazing. Unleash tactical assaults from a distance or go toe-to-toe with enemies. With co-op online multiplayer missions new to the Mass Effect universe, you can choose from a variety of classes and races, form a Special Forces squad, and combine weapons, powers and abilities as you all fight together to liberate key territories from enemy control in this third entry of an epic intergalactic RPG franchise.
