Created by GA America, Big Box served as the corporation's headquarters. A massive triangular building that was armed with large caliber cannons and surrounded by smaller similar buildings, Big Box was often touted to be an impenetrable fortress. It was eventually abandoned by GA after they took to the Cradles, and was taken over and used by ORCA as one of their main bases.
The base was eventually attacked by the League, led by Wynne D. Fanchon and the Protagonist, resulting in the deaths of Vaoh and Malzel, as well as the capture of Big Box. In Hard mode, the smaller buildings are shown to be able to float in the air and move about thanks to giant boosters attached to their bases. It is located in North America.
