The German version of the game has several censored differences from the international version:
• Blood is removed.
• Some of the more graphic deaths are made less violent.
• Corpses cannot be set on fire.

Mission 9 was based on Origin Systems offices in 1995. The level (designed by developer Mel Green) contains a maze to the south of the map where in real life Customer Support and Quality Assurance were located, and a square table in the middle which was in real life nicknamed the "Detention Hall." The northern end of the map is where the team for Crusader was located.
