Battlezone is a first-person shooter tank combat game released for arcades in November 1980 by Atari, Inc. The player controls a tank which is attacked by other tanks and missiles, using a small radar scanner to locate enemies around them in the barren landscape. Its innovative use of 3D graphics made it a huge hit.

With its use of three-dimensional vector graphics, the game is considered to be the first true 3D arcade game with a first-person perspective, the “first big 3D success” in the video game industry, and the first successful first-person shooter video game in particular, making it a milestone for first-person shooter games.
