Check out the first ever gameplay footage from the Microsoft press conference at E3 2011.
Mass Effect 3 will begin with Commander Shepard on Earth for trial as a result of events from the Mass Effect 2 DLC pack Arrival. During the trial, Earth is attacked by Reapers. Faced with insurmountable odds, Shepard is forced to flee the planet in order to gather support from alien civilizations and mount a counter-attack while also having to deal with Cerberus, who have decided to turn against him/her.
Casey Hudson said of the plot, “Mass Effect 3, in simple terms, is a little more like the first game. You’re collecting pieces of a story, but the more you investigate and explore these themes, the more the game will unlock and you’ll see the bigger picture. In a way, it’s more of a traditional story where you’re learning about things and the plot changes as you find things out.”
