Metal Force

Earth’s explosive population has caused food shortages and pollution.

Accordingly, the Earth Federation develops a plan to develop on alien planets and transfer Earth’s residents.

The Earth Federation sends scientists and troops to develop extraterrestrial planets in preparation for the transfer plan, and the overwhelming and successful forces of the troops complete the development of the extraterrestrial planet and make it suitable for human life.

Some scientists and troops who refuse to accept the control of the new United Nations and have joined forces to revolt and take over the alien planet. The United Nations decides to dispatch the METAL FORCE, a battle robot for aggression developed by the Defense Research Institute.
