The year is 2054. The Jådak Empire sends a vanguard to infiltrate Earth for an all out invasion. Armed with superior technology, the Empire quickly takes full control of Earth. They set up a puppet government headed by humans who are loyal to the Empire. Only a handful of freedom fighters remain to challenge them. Out gunned and out numbered, Earth's best hope lies in a secret project called XR5000, AKA "Mech Destroyer".
