Bioware's original space-opera trilogy concludes with Mass Effect 3, in the signature RPG-shooter style of its predecessors. Players resume the role of series protagonist Commander Shepard, once again customizable in appearance and character development. Combat is made more challenging by smarter computer-controlled opponents that adjust their tactics in the middle of a fight. An increased emphasis on melee and movement leads to closer, more furious combat. Players chart the course of the adventure, by travelling to remote planets and choosing which missions to attempt.
Decimated by a force of soulless invaders, known only as the Reapers, the human race is on the brink of extinction. It is left to the player to ply influence, make alliances, and discover the galactic secrets that are the last hope of human survival. Players have the option to import saved data from both previous Mass Effect games, in order to continue their own personalized adventure narratives, or to start fresh with a new personalized iteration of Earth's last hope. Shepard adventures along with a diverse crew of specialists, also customizable by the player. Weapons can be upgraded with scopes, grips, and other looted parts.
