The game features tanks, jet planes, prop planes, helicopters, and weather balloons on the screen, which try to destroy the player's saucer. There are also trees and houses on the ground that can be shot for extra points. The player needs to avoid colliding with the various enemies and their fire, or one of the player's three saucers will be lost.
Extra saucers are awarded for each 1000 points earned. Several game variations are included which control the game difficulty, the movement abilities of the enemies, and the movement abilities of the player's saucer.
