Space Wars

Space Wars is a shooter game released in arcades by Cinematronics in 1977. It is based on the PDP-1 game Spacewar! (1962) but instead uses vector graphics for the visuals. The hardware developed for Space Wars became the platform for most of the vector-based arcade games from Cinematronics. It was distributed in Japan by Taito in 1978, and a Vectrex port was published in 1982.

Gameplay


Two players controlled different ships. One button rotated ship left, another rotated the ship right, one engaged thrust, one fired a shell, and one entered hyperspace (which causes the ship to disappear and reappear elsewhere on the playfield at random).

The game offered a number of gameplay options, including the presence or absence of a star in the middle of the playfield (which exerted a positive or negative gravitational pull), whether the edges of the playfield wrapped around to their opposite sides, and whether shells bounced. The game had three particular features: First, the game could not be played in "one player" mode; a human opponent was required. Second, the player's ship could take a glancing hit without dying, but would suffer damage; a cloud of loose ship fragments would break off and float away, after which the ship would be visibly damaged on screen and would turn and accelerate more slowly. Third and most memorable was that the duration of play for any contest was solely governed by the amount of money deposited; each quarter bought a minute and a half of play. A dollar bought six minutes, and for a ten dollar roll of quarters two players could play non-stop for an hour.

Development
Larry Rosenthal was an MIT graduate who was fascinated with the original Spacewar! and developed his own custom hardware and software so that he could play the game. Cinematronics worked with Rosenthal to produce the Space Wars system.

Reception
Space Wars  sold 10,000 arcade cabinets in 1978. It was the highest-earning arcade video game of 1978 in the United States. It was later the sixth highest-earning arcade video game of 1979 in the United States.

Electronic Fun with Computers & Games magazine gave the Atari VCS version a C rating in 1982.

Legacy
Space Wars formed the basis of the platform used by Cinematronics for their subsequent black-and-white vector games such as Star Castle and Tail Gunner.
