Atlus plans on giving pre-order customers of Persona 4 Arena a bonus music CD. This Persona 4 Arena Arranged Soundtrack disc is a limited run affair; it contains selected songs from the musical score for the upcoming fighting game. The stage themes are based on the music of Persona series composer Shoji Meguro.
As always, this is a "while supplies last" kind of deal, so you'll want to be sure you have your pre-order in for your preferred platform (Xbox 360 or PS3) as soon as possible. August 7th is the official release date, so you have some time.
Atlus says that they'll release additional details on this bonus offer at a later date. m
