This sci-fi action game is set 400 years in the future, when disease has wiped out the majority of the Earth's population except for one walled, protected city-state, Bregna, ruled by a congress of scientists. Æon Flux, the top operative in the underground 'Monican' rebellion, led by The Handler. When Æon is sent on a mission to kill a government leader, Trevor Goodchild, she uncovers a world of secrets which make her doubt her mission and question everything she thought she knew.

This is not the first attempt at an Æon Flux-based videogame. A game based more closely upon the animated series was announced in the late 1990s for the PS1, to be developed by Cryo Interactive and published by Viacom New Media. Eventually it was cancelled, but the assets of the game were reworked into a title called Pax Corpus, which retained no elements from Æon Flux.

A commercial advertising the game was even included on the VHS release of the series, however this game was ultimately vaporware. Uncoincidentally, a commercial advertising the 2005 game was included on the DVD release of the TV series that same year.

Another stillborn project was attempted by The Collective and to be published by GT Interactive sometime around the year 2000. It was using a then-current version of the Unreal Engine, and appeared to be a 3D third-person action title similar to The Collective's title, Star Trek: Deep Space Nine: The Fallen. Again, however, at some point developement was cancelled and the project vanished.

Aeonflux.org chronicles the previous attempts, including early screenshots of the unreleased games. Gamespot also has some more information on the cancelled PS1 title by Cryo.
