The Planet Novenia has been attacked by the Egrons, who snuck in by disguising their craft as the protected Starglider species, which Novenia's automated defenses were programmed not to shoot. Your task is to fight them off using only an obsolete Airborne Ground Attack Vehicle. This was designed as the ultimate combat machine, with sophisticated hardware up to Draziw Yarg's high standards. It has a fully-rechargeable shield, plasma drive unit, an inbuilt scanner and 10,000-sector map, a top speed of 2550 Urads and two homing missiles. The game is viewed from within AGAV's cockpit, with control over speed, weapon targeting and firing. There are several control options to decide exactly how the craft works, with fixed or floating sighting, and the option of automatic centering, allowing you to balance the game between easy sighting and advanced shooting ranges. Repair depots must be visited frequently, as they can refill the weapon bays as well as repairing the ship. Crucially, the Egron Stargliders need 3 missiles to shoot down, so at least 1 visit to a depot is required to complete this job, at which point you move up to the next, harder, level.
