Retaining the gameplay from previous Mega Man games, Mega Man 3 has newer gimmicks, like additional 4 Doc Robot stages after defeating 8 Robot Masters, E-cans that replenishes health to 100%, and a new companion support robo dog named Rush.

But in order for Gamma to be operational, they need rare elements found in neighboring planets.

Mega Man is tasked to stop the Robot Masters, however, a mysterious red robot known as Break Man tries to hinder him.
