Somewhere there is some evil professor lurking about in his laboratory, doing mad science and what not. His latest doomsday creation is Mr. Roboto; a deadly fighter robot! But the robot develops self awareness somehow, and decided he don't want to kill things after all.
Mr. Roboto has to use his doomsday hardware to demolish certain blocks in each level. This to trick the drones out of the map so he can head on to the next area.
He has to use the environment to his advantage. Every block is destructible, Roboto has to place his limited amount of explosives carefully. Sometimes he even have to use the drones before he destroys them, stuff like riding them over dangerous electro magnetic fields (since Mr. Roboto's metallic feet are so tender, and the drones has special plastic wheels).
