The year is 2056!

The invention in 1966 of the electron drive, incorporating the Tesla coil, launched mankind outward into the Solar System. There, the nations of Earth found new allies and new enemies: the savage reptile-men of Venus…the many strange races of Mars…and the terrifying Overlord of Jupiter, emperor of its many moons! Earthers accidentally gave him the secret of the electron drive, allowing him to attempt to expand his reign across the whole system. In the tragic war that followed, the First Solar War, the Solar Patrol was commissioned. Its mission – defend Earth from all enemies! After a long and bloody struggle, Earth forced the Overlord back to Jupiter, where he continues to scheme against the free peoples of the System. Yet no matter how cunning his plots, the daring men and women of the Solar Patrol will always foil them!
