Battlezone is a coin-op game from Atari released in 1980. It displays a wireframe (using vectors rather than raster) wiew on a horizontal black and white CRT (with colour overlay). The vector technique is simmilar to games such as Astroids. The game was designed by Ed Rotberg who also designed Red Baron is somewhat simmilar. A version called Army Battlezone was also designed for use by the US army for tank gunnery training, but only two of them were produced although the gunner yoke developed was later re-used in the Star Wars game.
