Tank was released on November 4, 1974 by Kee Games. The game was developed by Kee Games. Tank is a two player battle game.
This game is sometimes known as Ulta Tank but the game in 1974 was not very sophisticated.
The monochrome CRT is able to show black and white players and the score is shown in shades of grey.
Tank was designed by Steve Bristow, who had previously worked with the founders of Atari on Computer Space, the first arcade video game, and was developed by Lyle Rains.
Tank is a two-player maze game in which the players, each controlling a tank, attempt to shoot each other. The maze is a set of blocks set at right angles to each other with an empty square central area all viewed from above; the shape of the maze is not symmetric, and is the same between games.
One of the tank sprites is white and the other is black, while the central area is filled with black X marks representing land mines. The tanks can fire shells, which destroy the other tank if they hit; tanks are also destroyed if they hit a landmine.
The destruction of a tank grants the opposing player a point and causes a brief explosion and accompanying sound, during which time the other tank cannot shoot, before restoring the tank at the same position. Destroyed land mines do not return.
Points are displayed above the play area, and flash during the final twenty seconds of the round. The game continues until the time runs out, after which the player with the higher point value wins the match. Each game typically costs a quarter and lasts for 60 seconds, but an internal toggle adjusts it to two quarters and 120 seconds. The time can be further adjusted by operators.
Tank was one of the first games to use integrated circuit-based memory—specifically, mask ROM (read-only memory)—to store graphical data, rather than the diode arrays that previous arcade games used; it is sometimes claimed in sources to be the very first, but was preceded at minimum by Atari’s Gran Trak 10 (1974).
