Set 200 years in the future in an epic universe, Mass Effect places gamers in a vast galactic community in danger of being conquered by a legendary agent gone rogue. A spectacular new vision from legendary developers BioWare, Mass Effect challenges players to lead a squad of freedom fighters as they struggle against threatening armies to restore peace in the land.

Mass Effect is the first in a trilogy of games with an overarching story. As the first human Specter – sworn defenders of galactic peace – your mission is to halt the advancing armies of a legendary agent gone rogue. But as you lead your elite team across hostile alien worlds, you will discover the true threat is far greater than anyone imagined.

The last of a deadly race of aliens is imprisoned inside a scientific research facility. This is the Queen; the leader of her species and the only survivor of a terrible cross-species conflict that left an entire race in tatters and cost the lives of millions. She pleads with you to spare her life - she knows her kind went down the wrong path and she wants to start again; all you need to do is release her and give her the benefit of the doubt. Or, you could ensure that her species is never given the chance to wage war again - it's a safer option, but killing her means final, damning extinction. What do you do?
