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.
