Gameplay
Before starting the selected mission, the player must choose a type of plane. Different planes have different engine, turning, speed, firepower, fuel, vitality and payload statistics. The player can also play as an enemy plane by pressing the right directional key. In the shareware version only two planes and three enemy planes are selectable. When the plane has been selected the player can decide how many missiles and bombs to take on the plane until the payload limit is reached. More powerful bombs take up more payload and have bigger destructive ranges. After the plane inventory has been arranged the mission can begin.
The player launches a plane from a supply bay. Bombs and maneuvers can cycled through. Air targets can be destroyed with projectile firepower. Missiles can be used to seek enemy planes at short range. Ground targets can only be destroyed with bombs. A target indicator is right in front of the plane used to indicate where a bomb that is launched will detonate once it lands in seconds. The target indicator has a further range from the plane when the plane goes at faster speeds. The first type of maneuver makes the plane temporarily invulnerable to enemy fire and use up some of the engine power. The second type of maneuver temporarily supercharges the speed of the plane for a quick getaway, but sacrifices larger amounts of fuel.
The plane takes damage from enemy fire or crashing into enemy planes. The plane is destroyed when the vitality metre or the fuel metre is depleted. The player has infinite chances unless all the supply bays are destroyed. When one supply bay is destroyed the plane will come out of the next nearest supply bay. A supply bay can be landed on when the plane hovers across it at slow speeds to refuel and resupply inventory, to change plane type and to change choice of inventory.
The player has a radar to seek and watch out for various targets. Enemy planes are indicated as yellow dots. Enemy planes will infinitely respawn until all the launch bays have been destroyed. Anti-air ground targets are indicated as red dots. Special ground targets are indicated as light green dots. Main ground targets are indicated as white dots. Hidden ground targets don't have a radar indication but are shown as grey dots on the mission map. All main ground targets must be destroyed to complete a mission.
