Planet Earth in the year 2XXX. You are relaxing at the console of your computerized superconductor-generated interplanetary satellite communications system. Suddenly, high frequency radio and television transmissions blast warnings to all inhabitants to prepare for the brutal invading forces of Balangool Empire.

You take control to defend and preserve the lives and freedoms of the people on Planet Earth. You shed your earthly identity. You unite with freedom fighter Captain Commando to become the one remaining astronaut in space. 

Concealed in your special solar-energized, jet-propelled supersonic spacesuit, fully armed with quick firing multi-dimensional weaponry, you leave Earth on you death-defying mission.

The Mission: battle and defeat the space soldiers of Balangool. Penetrate their base divided in section A through SECTION Z, then destroy Balangool master control "L-Brain."
