BioShock Infinite includes a song performed by its voice actors
Voice actors Troy Baker and Courtnee Draper perform a song called Will the Circle Be Unbroken on the BioShock Infinite soundtrack.
Baker and Draper play the roles of Booker DeWitt and Elizabeth respectively, so it's quite a special thing to hear them singing. Irrational Games provided a short preview of the track, which you can check out below.
BioShock Infinite's soundtrack was put together by Gary Schyman, who was responsible for past BioShock soundtracks, and will be included in the Ultimate Songbird and premium editions when BioShock Infinite launches for PC, PlayStation 3 and Xbox 360 at the end of the month.
