As if that massive four disc soundtrack that followed FFXIII's December release wasn't enough, Square Enix has a new soundtrack on the way for the RPG hit.
The Final Fantasy XIII Original Soundtrack PLUS soundtrack will feature the background music that was added to the overseas version of the game. This was, obviously, not included in the January compilation. There will also be some newly arranged tracks from composer Masashi Hamauzu.
Look for the Final Fantasy XIII Original Soundtrack Plus version on May 26 at ¥2,500. Pre-orders are now being taken at the Square Enix online shop.
