The Leather Goddesses of Phobos are just finishing up their plans for the invasion of Earth. You've been abducted by the Leather Goddesses for the final testing of the plan which will enslave every man and woman on Earth. If you fail to escape and save humanity, the Leather Goddesses will turn the Earth into their pleasure dome.
Copy prevention
The game featured no copy prevention as such, but like many Infocom games, it included puzzles that were nearly impossible to solve without hints from the accompanying documentation. In Leather Goddesses, these hints were included in The Adventures of Lane Mastodon, a small booklet formatted like a comic book.
Spoiler warning: Plot or ending details follow.
Given that the game was never meant to be solved without this information, even the most die-hard interactive fiction fan need feel no remorse for using the clues. These are not the Invisiclues—the clues that could be used to play the game from start to finish without solving a single puzzle.
Messages from Mars may be encoded in a three-letter transposition cipher. To decode them, D becomes A, E becomes B, and so on.
Catacombs are much easier to cross if you have a map.
It's safe to cross stagnant water if you know what you're doing. Clap your hands at least once every five minutes to scare away canal beetles. Hop once every nine minutes to frighten any bottom-crawling sand crabs, and make the distinctive "kweepa" sound of a martian hawk every eleven minutes to take care of any 'gators.
The LeatherGoddesses of Phobos are just finalising their plans for the invasion of Earth.
In a particularly clever way, LeatherGoddesses forces the player to "choose" a gender for his or her character: the game's first scene is in a bar, and the player's character has a sudden, powerful urge to urinate.
Further, LGOP assumes that the player's character is heterosexual, in that in "Lewd" mode a variety of sexually suggestive situations with the opposite sex are encountered.
Phobos was discovered by American astronomer Asaph Hall on August 18, 1877, at the US Naval Observatory in Washington, D.C., at about 09:14 GMT (contemporary sources, using the pre-1925 astronomical convention that began the day at noon, give the time of discovery as August 17 16:06 Washington mean time).
Phobos was photographed close-up by Mariner 9 in 1971, Viking 1 in 1977, Phobos 2 in 1988, Mars Global Surveyor in 1998 and 2003, and by Mars Express in 2004.
Phobos' phases, in as much as they could be observed from Mars, take 0.3191 days to run their course (Phobos' synodic period), a mere 13 seconds longer than Phobos' sidereal period.
