In 1974, Kee Games, a subsidiary of Atari, Inc., released an arcade game called Tank! It was a two-player game where players had to drive around a maze and destroy the other player’s tank. Although its graphics were simplistic black and white from a fixed top-down viewpoint, the game was extremely advanced for the time. Its control system was outstanding; it used two single-axis (up and down) joysticks to steer each vehicle as if each stick were controlling an individual track on each side of the tank.
