Chou-Wakusei Senki - MetaFight (Japan)

About

In the Japanese version (Chō Wakusei Senki Metafight), the plot is only explained in the manual. The game takes place on the planet Sophia the 3rd, located near the center of the Epsilon Galaxy, in which an advanced civilization flourished. In the year 2052 of the space age calendar, the Invem Dark Star Army, led by the universe's most feared tyrant Goez, invade and conquer Sophia the 3rd. The Science Academy of NORA, a satellite orbiting near Sophia the 3rd that somehow managed to avoid the invasion, built a weapon, an all-purpose tank called the "Metal Attacker", in a last-ditch effort to defeat Goez's army. A young soldier named Kane Gardner is chosen as the pilot of this weapon. The game's opening sequence shows Metal Attacker dropped into the battlefield.[3]
