Mass Effect X360 comments

Mass Effect delivers an immersive, story-driven gameplay experience
presented in a cinematic style with high production values, extraordinary levels
of visual fidelity, incredible exploration and realistic digital actors.

Players assume the role of an elite human Spectre agent, Commander Shepard,
entrusted with keeping law and order in the galaxy. The player uncovers a threat
so great it could destroy all life in the galaxy. As the only human Spectre,
Commander Shepard's job is complicated by the fact that no one will believe the
word of a human, a race not fully trusted by the other alien races. However, the
galaxy must be convinced of the grave threat at hand or all life could be
exterminated.

Players travel across an expansive universe to piece the mystery
together. As they discover and explore the uncharted edges of the galaxy, they
come closer to an overwhelming truth — learning that the placid and serene
universe they know is about to come to a violent end and that they are the only
being who can stop it. Throughout Shepard's exploits, players will face morally
challenging decisions that will impact the future of all races, and how humans
are ultimately viewed on the galactic stage.
