Regional differences
In the European versions, the main characters, as well as many humanoid-like enemies, were replaced with robots due to a German law prohibiting showing violence to minors. This change also expanded to the Helicopter at the end of the game, which now resembles a futuristic looking jet. The life icon (which was a medal) was also changed (now being a miniature Probotector). Because of sprite changes, some objects, characters and parts of the stages have minor palette changes (an example includes the third boss, Gromaides, having different arm colors). Enemy bullets have also been changed from white to red.
