The Fromm Gang facility had eight levels, each allocated to a different purpose. The very bottom level operated as a prison, while built on top of this were mining, factory, and research levels. These were followed by a level allocated for domestic purposes, communication, security, and finally control. The levels were separated by numerous elevators activated by entering the correct sequence of colored keys. Also installed at various points on the ceilings of these levels were gun emplacements.
