Tharolian Tunnels is a fixed shooter for the Apple II family of computers programmed by Rod Nelsen and published by Datamost in 1982.

Softdisk magazine, issue 76, gives this brief description of game's premise: "Free the planet Tharolia from rule by maniacal machines.

"[2] Similar in style to Space Invaders and Datamost's Cavern Creatures, the game puts you in control of a single armed spacecraft pitted against numerous waves of attacking aliens.

The player first selects from three levels of difficulty—1) Pilot, 2) Captain, or 3) Commander—and then faces the first challenge, an attack by a slowly descending formation of aliens.

Subsequent levels throw different challenges at the player, such as carefully navigating down narrow, winding tunnels, dodging and attacking oncoming aliens and passing through pulsing energy barriers.
