Gameplay in Mass Effect 3 is influenced by decisions from Mass Effect and Mass Effect 2. Combat has been changed and refined; in particular, the cover system has been improved, there are more options for moving around the battlefield, instant melee kills and more conventional grenades are introduced as well as improved artificial intelligence. A four player multiplayer co-op mode is also available.
Mass Effect 3 runs well on a wide cross section of hardware. The Titan 8500i Vortex system maintains smooth frame rates throughout, dropping to 39 fps once.
