Further inspection reveals that this planet is inhabited solely by women; in a terrible war between sexes, the female population annihilated the male one with biological weapons, and is now artificially procreating with a device called the Gender Bender.
Rex is soon captured by the planet's cruel elite forces and must find a way to escape while preserving his virility.
Rex Nebular and the Cosmic Gender Bender is a puzzle-solving adventure game with light erotic and comedy elements, somewhat influenced by Leisure Suit Larry and Space Quest series.
The interface resembles the one used in most LucasArts games of the time period: the player chooses verbs from a menu at the bottom on the screen, interacting with objects on screen.
Some collected items have their own, unique actions that can be performed with them that are not available on a general list of possible actions.
Most of the puzzles are inventory-based.
The game is linear but some goals may be achieved in different ways.
There is no way to get stuck - the game does not allow the player to progress further beyond specific moments without all the needed objects or actions.
Three difficulty levels are available what makes some puzzles more or less complex - in the easiest difficult level some actions are not required or/and some objects may not exist at all.
The game has four different endings and only one of them is a happy one.
The endings depend on the actions the player did (or did not do) in the final section of the game.
About Commodore 64
Released in 1982, the Commodore 64 is the best-selling home computer model of all time, with an enormous software library spanning games, productivity tools, and everything in between. C64 game collecting centers on cassette tapes and floppy disks in their original packaging — physical media that's inherently fragile, so complete, working copies from the era are increasingly prized by retro computing collectors.
Gamevaro tracks Cosmic Tunnels for Commodore 64 with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Cosmic Tunnels to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This C64 release dates back to 1983.

Rarity & condition
Only a handful of market sales have been tracked for Cosmic Tunnels, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Commodore 64 titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
