The story involves two fictional countries, the peaceful Republic of Sardun and their aggressive neighbor Gamibia. Unable to defend themselves from a Gamibian incursion, Sardun sends Major Zara and General Byrne-White to ask the help of MegaForce - a secret army composed of international soldiers from throughout the western world, equipped with advanced weapons and vehicles. The MegaForce leader, Commander Ace Hunter, will lead a mission to destroy the Gamibian forces, which are led by his rival, and former military academy friend, Duke Gurerra.
