Mass Effect is an award-winning, bestselling series of science fiction RPG third-person shooter video games developed by the Canadian company BioWare and released for the Xbox 360, Microsoft Windows and, from the second installment, for the PlayStation 3. The first game in the planned trilogy centers around a player created character named Commander Shepard and his/her mission to save the galaxy from a race of mechanical beings known as the Reapers, and its followers, including the brainwashed Saren Arterius. The first game sees Shepard facing Sovereign, a Reaper left as a vanguard, who plans to allow the Reaper fleet currently hibernating in extra-galactic dark space to invade the Milky Way and destroy all sapient organic life, continuing a mysterious cycle of destruction. The second game takes place two years later, and sees Shepard battling the Collectors, an alien race abducting entire human colonies in a plan to help the Reapers return to the Milky Way. The third and final game will center on the final battle against the Reapers.
