Description
Moving a crosshair across the sky to launch a counter-missile strike was very appropriate for the political atmosphere of the early 80s. This was Atari’s huge arcade hit and an instant classic later ported to countless gaming consoles.
As with all Atari games of that period, Missile Command has a unique pinout. While the original game uses a trackball, the adapter has an on board micro-controller based trackball emulation layer so the game can be played with a standard JAMMA joystick.
