Zone X is a maze video game designed by Derek Johnston and published by Gremlin Graphics in 1985 for Atari 8-bit computers.

The player will lose his life if he fails to deposit the plutonium in the container within the allotted time.

The player can also find useful items such as keys used to open locked doors, shovels useful for digging through crumbling walls, or mats that block robots and can be used to confine them in an enclosed area.

To complete each level, the player must dispose all the plutonium into containers and find the exit door.

Richard Vanner writing for Atari User advised to "forget the cover and enjoy the story".
