Stupid Invaders

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.

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.

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.

The game received "mixed" reviews on both platforms according to the review aggregation website Metacritic. Daniel Erickson of NextGen said that the PC version "would have been better as a non-interactive cartoon."
