This game was the part of the basis for the Atari 2600 cartridge. There are three possible positions for each anti-aircraft gun, each selected by one of the control panel buttons. Pressing a button aims and fires the gun. Fixes Suffers from the standard Atari heat problems at the voltage regulator. The game is played against a timer.
Players compete against each other to shoot down the most planes before time runs out.
Flight direction is also random. There is no CPU and only one ROM that is for the plane's graphics. The timing signals and gameplay processing are all handled by individual TTL ICs. There is only one speaker. There is an undocumented option available that switches the planes into UFO's.
