Not everyone will survive. An ancient alien race, known only as "Reapers", has launched an all-out invasion 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. 

Mass Effect 3 plunges you into an all-out galactic war to take Earth back from a nearly unstoppable foe - and how you fight that war is entirely up to you. 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 elite, 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 using devastating melee assaults and the deadly omniblade.

You determine how events will play out, which planets to explore, and whom to form alliances with as you rally a force to eliminate the Reaper threat once and for all. How you wage this war is completely up to you: go into combat with guns blazing or use cover to plan a more tactical assault. Utilize your squad to full effect or take a lone wolf approach. Rain death from a distance or go toe-to-toe with enemies using devastating melee attacks. Mass Effect 3will react to each decision you make as you play through a truly unique experience of your own creation.
