User Summary Zone Ranger is essentially Asteroids with a much bigger map. You fly a ship around, according to simplified Newtonian physics, and blow up asteroids and space ships. There are wormholes which take you to other parts of the map, wormholes which take you to different levels, and even a mysterious wormhole which warps you into a maze-like level. Released by Activision for the Atari 8-bits.
