The earth is besieged by Godzilla and monsters, and is in a critical situation. Who will be the ultimate winner, human wisdom or the instincts of the monsters? A highly challenging yet simple simulation game to play! Just choose the commands from the "pop-up" menu and all operations can be done easily. Concentrate on your battle strategy and destroy all the enemy monsters on the earth. Popular monsters are up against the newest "smart" weapons! As the commander of the Allied Defense Forces, you place those controversial smart weapons on the map. Fire and attack as you see fit. There are even some monsters that come to the aid of the Allied Defense Forces!
Japan is being ravaged by bizarre and powerful giant monsters. A reptilian creature called Baragon is creating earthquakes in an oil refinery, a high-speed pterosaur named Rodan is leaving sonic booms in his wake, a hideous blob of slime called Hedorah is feeding off of the city's toxic waste and growing larger every second, a giant caterpillar named Mothra is laying eggs in different parts of town, a giant octopus is destroying fishing ships in the harbor and devouring their crews, a terrible three-headed hydra named King Ghidorah is bringing fire to the skies, and Godzilla is plowing through everything around him. To make matters worse, a fleet of alien saucers has begun an invasion. Only the J.S.D.F. can stop them.
