Rex Nebular and the Cosmic Gender Bender is a point-and-click Adventure Game developed by Microprose. It is one of the three games based on Microprose's MADS engine, along with Dragonsphere and Return Of The Phantom.
The game is set in a comedic Space Opera universe similar to Space Quest, except that the humor is a lot raunchier and more sexist. The protagonist, Rex Nebular, is a lone space traveler doing odd jobs. One such job required Rex to retrieve a precious vase from a cloaked planet called Terra Androgena. Rex finds the planet quite easily with his mass indicator, but finds out very soon that the planet's exclusively female inhabitants are very hostile to outsiders, especially if they are male. Rex's ship is shot down, though he manages to survive the crash-landing on the planet. He must now find another way off the planet, as well as complete his original objective find the precious vase.
- Does Not Like Men: The women of Terra Androgena openly treat all men as subhuman beings. Any men that make it to their planet are relegated to the role of breeding stock.
- Excuse Plot: Rex being hired to find the vase exists pretty much just as a reason to get him to the planet for hijinks to ensue.
- Gender Bender: There is actually a machine called this in the game, and it does Exactly What It Says on the Tin. The women of Terra Androgena use it to continue their race, though they find the process extremely degrading. Rex himself has to use it at one point.
- Gendercide: The Great Gender War ended in this, as the women developed a virus that killed all the men.
- In Medias Res: The intro starts with Rex presenting the vase to his employer, Colonel Stone, and the game is basically his retelling of how he got it.
- Lady Land: Terra Androgena is this, after the successful Gendercide of the male population in the Great Gender War.
- Unwinnable by Design:
- There are two Tough moments when you need to retrieve certain items or complete certain objectives, and you will be unable to do so after you do a certain thing. In both cases, the game will give you a pop-up warning that you are about to do so. The first one is when you are about to leave the Slippery Pig, and the second one is when you are about to flood Machopolis. Otherwise, the game is Polite or even Merciful. Rex can die, but the game will always restart at the moment before the fatal mistake was made.
- In Machopolis, there is also one puzzle where this trope is subverted. You can lose both of your bones and still not get rid of the dog at Abdul's Service Station, but you can later get new bones when you get up the south elevator.
