Definitely one of the best soundtracks out there! It's sounds very techno, and makes me want to go and play the game whenever I hear it! Chaos Field itself is one of the best shoot 'em up games out there, but it doesn't really get a lot of attention for some reason. It's definitely a hidden gem that can be found on GameCube, Dreamcast, and arcades. The music from it certainly helps show how outstanding this game is!
