A 4LP box set with Gustavo Santaolalla’s score for the game as well as the music from the Left Behind DLC has been released by Mondo. The initial run was limited to 2,500 copies, while the second run (scheduled for December 2015) will be limited to 1,500 copies.
The second run has been delayed due to a production issue wit the slipcase box. It’s estimated to begin shipping in January, 2016.
