1001 Video GamesThe PC and PS1 versions of Oddworld: Abe's Exoddus appear in the book 1001 Video Games You Must Play Before You Die by General Editor Tony Mott.
ManualThe manual of Oddworld: Abe's Exoddus came packaged with a catalog of Oddworld merchandise. The catalog was printed on the back reading to the inside, and printed upside down (so that you had to flip the manual over to read it).
Multiple endingsThe game has two different endings: the happy ending and the sad ending. Which ending you get depends on the number of mudokons you have rescued during your quest (there are 300 of them). Some Mudokons you just have to save in order to progress, others are hidden in secret areas. You need to save 150 mudokons to get the happy ending. You do play the same levels with each ending though.
