Space Duel is an arcade game released in 1982 by Atari Inc. It is a direct descendant of the original Asteroids, with asteroids replaced by colorful geometric shapes like cubes, diamonds, and spinning pinwheels. Space Duel is the first and only multi-player interactive vector game by Atari. When Asteroids Deluxe did not sell well, this game was taken off the shelf and released to moderate success.
The player has five buttons: two to rotate the ship left or right, one to shoot, one to activate the thruster, and one for force field. Shooting all objects on the screen completes a level. Space Duel, Asteroids, Asteroids Deluxe and Gravitar all used similar 5-button controlling system.
