The game is simple where the objective is to navigate and shoot your way through the sky. There are enemy missiles which travels from right-to-left with varied speed. These enemy missiles can be destroyed by shooting at them. With increase in game level, SAM launchers also moves on the ground, which can fire targeted missile at the jet. These missiles cannot be destroyed, so user needs to evade them.
