Space Duel

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 vector game by Atari. When Asteroids Deluxe did not sell well, this game was taken off the shelf and released to moderate success. There were no contemporary home ports.

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.
