Thrusters was inspired by the cabinet graphics for Atari Space Duel. Space Duel was a sort of like a fancy Asteroids where two players’ ships could be linked together. It was a color vector game. Instead of scan lines, like a normal TV set has, the electron guns in a Vectorbeam could be moved anywhere on screen. While other types of games were limited to chunky pixels, these games were able to render smooth lines. But the background had to be black.
