Battlezone is a first-person shooter tank combat arcade game from Atari, Inc. released in November 1980. The player controls a tank which is attacked by other tanks and missiles.
The game is considered to be the "first big 3D success".
The game uses wireframe vector graphics on a black and white (with green and red sectioned color overlay) vector monitor. Gameplay is on a flat plane with a mountainous horizon featuring an erupting volcano, distant crescent moon, and various geometric solids (in vector outline) like pyramids and blocks. The player can hide behind the solids or, once fired upon, maneuver in rapid turns to buy time with which to fire. The geometric solid obstacles are indestructible, and can block the movement of a player's tank. However, they are also useful as shields as they block enemy fire as well.
The player views the screen, which includes an overhead radar view, to find and destroy the rather slow tanks, or the faster-moving supertanks. Saucer-shaped UFOs and guided missiles occasionally appear for a bonus score. The saucers differ from the tanks in that they do not fire upon the player and do not appear on radar.
There is a gameplay modification at 100,000 points if the proper conditions are met. When executed properly the next appearing Supertank will not attack and will retreat. A tank icon will then appear at right on qualified high score listings
