A.E.

Robots developed for pollution control are running amuck, in this invasion contest. They swirl over the horizon and zoom hither and yon across the playfield, as they try to destroy the player's active cannon (three are available in all) as it moves back and forth along the bottom boundary. The idea is to push the crazed robots back wave by wave until, on the eighth screen, you move them more than 600 billion miles from Earth. A. E.'s shooting mechanic is unorthodox. The gamer pushes the action-button to launch a rocket, releasing it the instant at which detonation is desired.
