Computer Space is a space combat arcade video game released in 1971. Created by Nolan Bushnell and Ted Dabney in partnership as Syzygy Engineering, it was the first arcade video game as well as the first commercially available video game. Computer Space is a derivative of the 1962 computer game Spacewar!, which is possibly the first video game to spread to multiple computer installations. It features a rocket controlled by the player engaged in a missile battle with a pair of hardware-controlled flying saucers set against a starfield background. The goal is to score more hits than the enemy spaceships within a set time period, which awards a free round of gameplay. The game is enclosed in a custom fiberglass cabinet, which Bushnell designed to look futuristic.

An arcade video game takes player input from its controls, processes it through electrical or computerized components, and displays output to an electronic monitor or similar display. All arcade video games are coin-operated or accept other means of payment, housed in an arcade cabinet, and located in amusement arcades alongside other kinds of arcade games. Until the early 2000s, arcade video games were the largest and most technologically advanced segment of the video game industry.
