Based on the Atari coin-op of the same name, Battlezone for the Atari 2600 is a first-person tank shooter. Your basic objective is to drive around the countryside, shooting enemies while avoiding being shot. Unlike the vector-based arcade game, which used a periscope as part of its control mechanism, this home version of Battlezone is played using a standard joystick.
By the year 1999, all the nations of Earth have banded together in peace (according to this game, at least). Unfortunately, a renegade council of military commanders has disrupted this utopian existence by unleashing a battalion of automated tanks, aerial fighters, flying saucers, and supertanks upon the unsuspecting world. At the helm of an old military tank you found in a museum, it is your job to squelch this rebellion.
