This is the theme for what is widely considered one of the greatest boss battles in video gaming history. Red and Blue, the Heroes of "Gunstar Heroes" take a fast paced wild ride through an underground railway while riding tiny speeder pods that can reverse gravity on a whim. They do battle with various troops that ride similar pods as well as troops on a train with their leader, Smash Daisuke (who is basically M. Bison...but...yeah.). Once the train is destroyed, they get ambushed by Green, who pilots the Seven Force...a strange machine that morphs into seven forms: Soldier, Tiger, Crab, Urchin, Eagle, Magnum, and Snake. Enjoy it!
