Welcome to Dynatron City, where nobody's normal. Dr. Mayhem's atomic experiments produced six really cool superheroes... and an awful lot of enemies.

Battle your way through sewers full of Gatomorphs and Loogiehawks, streets crawling with rabid robots, and the malevolent Mega Mall, where you have your showdown with Atom Ed, the floating head. And then you're ready for Dr. Mayhem himself! Monkey Kid's banana bombs waste Loogiehawks! Radium Dog snaps up big bargains in Mega Mall! Buzzsaw Girl's blades stop metal mutants!
