Nine young people were turned into cyborgs by a company trying to take over the world. They have defeated this company and are now using their super powers to protect the world.
Based on the manga/anime by the same name, Cyborg 009 is a side-scrolling platformer in which the player takes control of 8 different cyborgs, using their special abilities to complete several missions.
Their special abilities are as follows:
002 can fly and hover in the air; 003 can see in the dark; 004 can fire bullets from his fingers and rockets from his knees; 005 can break rocks with his fists; 006 can blow fire that also melts rocks; 007 can take on different shapes including those of enemies; 008 can swim underwater for extended periods of time; 009 can move at very high speeds. (001 is a baby and can't be taken on missions). Using these special abilities consumes SP that slowly regenerate.
In addition to their special abilities, the cyborgs also have four attributes that govern their attack and defensive powers, their amount of SP and SP regeneration speed.
Before every mission, one cyborg is assigned leader and two more can be selected by the player. Only one cyborg can be controlled at a time, but it is possible to switch between cyborgs at any time. All cyborgs share the same HP and SP-bar. Throughout the levels, experience points can be collected and used to increase a cyborg's attributes after a completed mission.
