As a key part of creating the new content for the Extended Cut, the team called upon composer Sam Hulick with the challenge of creating new music that would bring the Mass Effect trilogy story to a warm resolution, and inspire the emotions surrounding a variety of different visions of the future. The result was over 16 minutes of powerful new music, which many fans in the BioWare Community have asked for in the form of a downloadable soundtrack. We are excited to release all 7 tracks of the Extended Cut soundtrack for free – right here on the BioWare Social Network site!
Keep in mind that if you got the soundtrack with the pre-order of the game, this is not the same thing. This is the soundtrack for the extra DLC with the Extended Cut.
Thank you, Bioware! It sounds great!
