In the year 2032, globalization has blurred the borders between countries, and multinational corporations have become worldwide economic superpowers. General Resources Ltd., one of these superpowers, uses state of the art military equipment and their Air Strike Force (A.S.F.) to destroy anybody who could potentially pose a threat to their superiority.

A new international military is created to fight back, spearheaded by an elite fighter squadron called the United Air Defense (U.A.D.). As the newest pilot, you must help your squadron destroy the ASF and bring General Resources Ltd. to their knees.
