German versionWhen playing the game with the German language setting, all gore effects (e.g. biting off an enemy's head) are deactivated by default and can't be activated. Additionally all blood was replaced with flowers. This does not apply to the Game Boy Advance version.
PDA mini gameThe European version has some additional features. Alongside the level editor, 25 of the best fan built levels from the US have been included for the PDA puzzle mini-game. A 2-4 player button basher called All You Can Eat featuring the Fat Kid is exclusive for Europe. Another new function allows you to rewind the level you've just completed and jump back in at any point.
With the Xbox version, you can download additional levels over Xbox Live for the PDA mini-game and check your ranking against other players on loads of different stats such as quickest time through the game, number of kills, buildings destroyed and number of head bites.
