Stupid Invaders

The game was dedicated to Jean-Yves Raimbaud, the co-creator of the TV series, who died before the game was released. Unlike the original show, the game is also reliant on toilet humor and is slightly more adult in nature, making it the first work produced by Xilam to be for an older audience, before Kaena: The Prophecy, Mr. Baby, I Lost My Body, Twilight of the Gods and The Wolf. Most of the staff members from the first season of the original series were involved with the game's production. The original cast reprised their roles as the main aliens, some of whom provide dialogue for some exclusive characters. The game features the additional voices of Billy West, Rob Paulsen and Laraine Newman, with Danny Mann (Gorgious) voicing an evil scientist from "Zero Stuff" and West voicing the antagonist, Bolok from "The Pro".

The plot centers around the aliens and their attempts to return to space. However, a bounty hunter, the stoic yet serious Bolok, is sent by an evil scientist, to target the aliens. Thus, Etno's attempt to explain his newest idea goes awry as the aliens are frozen solid by Bolok's gun – which forces Bud to retreat to the bathroom. Once he sneaks to the rooftop and sneaks around the house, the player progresses through the large, surreal world within performing very specific (and often absurd) actions, like melting Santa Claus and reducing him into green ooze.

All the main characters of the series are playable through the course of the game. The game rejects or distorts some clichéd aspects of the adventure genre, as standard adventure game tactics such as picking up, talking to, or interacting with anything encountered can often result in instant (albeit highly comical) death for the player's currently-controlled character and the need to reload, for example, often without warning. It should be noted the game does not support autosaving – players need to save manually before they progress any further.

Development of the game initially began at Gaumont through Gaumont Multimédia before the studio was shut down by Gaumont in 1999, and it was originally slated for release in December 1999.
