This is the in-game version of the end credits music for Mass Effect 3, "Das Malefitz" by Faunts. This version includes the instrumentals in the intro that are not present in the album version.
Even non-romanceable squadmates are kind of "romanceable" with the Citadel DLC.
Javik is my favorite char from the whole ME series, and I'm quite happy with the new content. :3
