Rally-X is a maze chase arcade video game developed in Japan and Germany by Namco and released in 1980. In North America, it was distributed by Midway Manufacturing and in Europe by Karateco. Players drive a blue Formula One race car through a multidirectional scrolling maze to collect yellow flags. Boulders block some paths and must be avoided. Red enemy cars pursue the player in an attempt to collide with them. Red cars can be temporarily stunned by laying down smoke screens at the cost of fuel. Rally-X is one of the first games with bonus stages and continuously-playing background music.
