Super Vehicle-001

 * In the year 2028, the evil General Morden and his rebel army launched a coup d'état on the world's governments, and all attempts by the armies of the various countries to curtail his power fail. His most recent attack has given him access to a new form of all-terrain combat tank dubbed "Metal Slug".
 * In a last effort to stop Morden, Cpt. Marco Rossi and Lt. Tarma Roving of the Peregrine Falcon Strike Force are sent to locate and eliminate his powerbase, as well as reclaim or destroy any Metal Slugs they can find so as to keep the technology out of Morden's hands.
 * After battling their way through hordes of Morden's soldiers, the duo face off against Morden, in a heavily armored helicopter. After defeating the helicopter and killing Morden, they destroy his base of operations.
 * In the epilogue, one of Morden's men is shown throwing a paper airplane from a cliff face. The plane flies across the various location the duo went across, from the destroyed Metal Slugs on the forest and the city where a woman grieves for her slain lover who is a Rebel Army member before disappearing into outer space.
