Keith Courage in Alpha Zones stars a hero who suspiciously looks like Gunstar Red. He is a part of the alliance N.I.C.E. (Nations of International Citizens for Earth), whose current 'mission' is to defeat B.A.D. (Beastly Alien Dudes) and bring peace to the world.
This TAS features speedy completion by using the inept enemies as boosts to speed through the underworld levels. Only 2 of the weapon upgrades are ever collected and all of the story is completely skipped.
There are also 2 cases of using an instant kill level hazard as a shortcut.
This game should probably have a seizure warning of some sort.
