Wintory's 20-minute collection includes eight tracks, with the first, 'The Legacy of Shepard,' referencing the original Mass Effect theme and blending analog synths with orchestral elements. The composer described the work as a 'hybrid approach' comparing it to The Matrix scores, created without knowledge of the game's narrative direction.
Wintory called Mass Effect 5 his 'ultimate white whale' and expressed grief over BioWare's closure, noting the loss of friends and the franchise's 'seemingly vanish[ing] forever.' He thanked BioWare and EA's music departments for the opportunity to contribute to the project.
