Mass Effect Legendary Edition contains single-player base content from all three titles in the Mass Effect trilogy: Mass Effect (2007), Mass Effect 2 (2010), and Mass Effect 3 (2012).[2] The compilation also includes almost all single-player downloadable content (DLC) that was originally released for each game, such as promotional weapons, armors, and packs.[N 1] The trilogy consists of action role-playing games in which the player assumes the role of Commander Shepard, an elite human soldier who must unite the galactic community against a highly advanced machine race of synthetic-organic starships known as Reapers.[4] Shepard is a customizable character whose gender, appearance, military background, combat training, and first name are determined by the player.[5] During each game, the player makes choices that can impact the story in various ways, including consequences that can be carried forward through the trilogy.[6]
