Konami's action-oriented flight combat series continues with AirForce Delta Storm, a follow-up to 1999's AirForce Delta on the Dreamcast. The setting is the year 20X1, where two factions battle for control of Earth's dwindling resources. As a pilot for the United Front, players must protect their allies while neutralizing enemies both in the air and on the ground. From destroying enemy fleets to cutting off supply routes, a total of 50 distinct missions are available. Players receive cash and statistics after each mission, such as time of completion, the number of kills, and the ratio of hits using machine guns and missiles. The more downed fighters, the more cash to purchase new planes. Each plane is rated in such areas as speed, power, defense, and mobility, with over 70 aircraft available to purchase.
