The game method is to control the launch pad at the bottom of the screen and drop the enemy above the screen to annihilate it. Sometimes UFOs can appear and get a bonus when dropping them. There is a defensive wall above the launch pad, and it is destroyed little by little when attacked. If even one enemy comes down to the bottom row, the game is over immediately regardless of the number of aircraft remaining. Also, there is no limit to the number of stages.
