Battlezone was a highly advanced game for its time, featuring a true 3D wireframe battleground and a cabinet with realistic tank-like controls and a periscope-like viewfinder – the fact that the gameplay mechanics were relatively simple didn't detract from its appeal in arcades. Players drive a tank around a sparse landscape filled with 3D primitives and enemy tanks, firing at enemies and moving two joysticks in the direction of the tank's treads (so to turn, you must push one forward and one back). The game's success helped pave the way for other 3D Atari titles, including the popular Star Wars, and the US Army was so impressed it commissioned a variant, The Bradley Trainer.
