Mass Effect combines real-time squad combat with decisions that shape mission outcomes, crew relationships and the narrative across the trilogy. Players choose companions and adapt their tactics to enemies ranging from biotic users to heavily armored machines. Exploration takes Shepard to the Citadel space station, alien homeworlds and remote outposts.
Set in 2183, the story follows Commander Shepard after a mission to recover a Prothean beacon on Eden Prime is disrupted by an attack. Appointed the first human Spectre, Shepard travels aboard the SSV Normandy to hunt the rogue agent Saren Arterius and investigate a threat that grows into a galaxy-wide conflict.
