Mass Effect 3 is the concluding game in Shepard's trilogy of BioWare's Mass Effect series. It is available for multiple platforms including Windows, PS3, and Xbox 360. There are many improvements over the previous iteration of the game, Mass Effect 2, including enhanced artificial intelligence and a four-player multiplayer co-op mode. It continues where the Arrival pack for Mass Effect 2 left off, continuing Commander Shepard's mission to save the galaxy from the Reapers.
Mass Effect 3 is backwards-compatible with the previous version, Mass Effect 2. Players can import files made by old versions of the game. There are three game modes: Action Mode, Story Mode, and RPG mode.
