Square Enix recently uploaded the opening sequence and tutorial for an upcoming mobile game for iOS and Android called Demons’ Score onto YouTube. For those who don’t know what it is, it’s basically a first-person on-rails shooter with Elite Beat Agent style controls. It’s a bit out there, I know. You play as Serenity, a college girl who’s trying to find her father. She travels to the place he usually works, which just so happens to be at a creepy asylum. While looking for her dad, she opens something called the Demons’ Score which causes demons to possess her. Like ya do.
The game’s soundtrack has a good amount of composers working on it, including Yoko Shimomura (Kingdom Hearts), Kohei Tanaka (Sakura Wars), Naoshi Mizuta (Final Fantasy XI), and more. And, as Siliconera reports, those composers are paired with popular voice actors (in Japan, anyway) for various boss segments.
