Since it appeared difficult and took me very long to find the whole Soundtrack, I figured I'd make it easier for all the other Berserk-Fans out there.
Here some general Info:
Berserk Millennium Falcon Arc: Chapter of the Holy Demon War original soundtrack is based on the second video game (for PlayStation 2) of the popular heroic fantasy Berserk anime TV series first broadcasted in Japan from 1997 to 1998.
Since then the TV series was released on DVD and DVD Box and distributed in Asia, America and Europe. Sammy's PlayStation 2 game was released in both Japan and Korea, but this OST was only sold in Japan.
Susumu Hirasawa, who did the anime music, composed Sign as the opening movie theme, and also made a remix of it for the end theme entitled Sign-2. Both tracks were produced by Chaos Union. However, the majority of the game's soundtrack was created by other composers namely, Shinya Chikamori, Hiroshi Watanabe, Yasushi Hasegawa and Tomoyo Nishimoto, all of them are Sound Ams produced artists.
