It is up to the blue robot Megaman to stop the plot of Dr. Wily, the maverick lab assistant, by jumping and shooting his way past an army of robots. At the end of these levels are three of Dr. Wily's robot masters, Dyna Man, Sonic Man and Volt man who each drop a key when defeated. These keys are then used to gain access to the room where the megacomputer Crorq is being stored for a final showdown. As always, Megaman can absorb the weapon power of the robot masters and use it as his own.
