Revenge of Cyon

A Cyon ship appears high in the night sky and sinks toward the ground, jumping from side to side to dodge your fire; the higher the skill level, 1 to 6, the wider it jumps. Steer the crosshair over it and press a button to shoot. You have seven shots per ship. A hit sends it fleeing and shows how many shots and seconds it took. From wave 7 two ships come at once, six columns apart and jumping together, and both must be hit. A ship that reaches the ground wrecks one of your three domed bases and the wave starts again. Lose all three bases and the game ends. Survive 11 waves to save the Earth, and the end screen gives your rank, from Private to Mr. President.

Controls: Use either controller. The stick moves the crosshair and either button fires. On the title, up and down choose, left and right set the skill, and a button starts.
