Rockman: The Power Battle is a Jump&Run Adventure from Capcom
The Story: The evil Doctor Wily has rebuilt some of his Robot Masters, with which he is trying to take over the world, forcing the heroes to stop him.
The game allows the player to choose between three playable characters: Mega Man, Proto Man, and Bass. Two players can play the game simultaneously and team up to defeat the bosses.
The game uses one button to jump, and one to fire the character's arm-mounted energy weapon. Holding the fire button charges the weapon in order to release a stronger blast. Holding down while pressing the jump button makes the character perform a dash, the appearance of which varies between characters.
After selecting a character, the player chooses between three "stories", with each one having different Robot Masters from various games. The "stories" are Mega Man 1-2, 3-6, and Mega Man 7. Upon choosing a "story", the game quickly pans through the various levels, letting the player choose one.
