Electronic Arts' BioWare debuted this new live-action trailer for Mass Effect 3 during Sunday's "The Walking Dead" episode.

Mass Effect 3 thrusts players into an all-out war to save the galaxy from an ancient alien race known as the Reapers. Players will assume the role of Commander Shepard, a war-torn veteran who's willing to do whatever it takes to eliminate this nearly unstoppable foe. With a team of elite, battle-hardened soldiers at your side, each player decides how they will take Earth back, from the weapons and abilities they utilize to the relationships they forge or break.

The game will be available March 6th for the Xbox 360, PlayStation 3 and PC.
