The map design has a evil genius theme with archetypical spy fortresses, concealed within inconspicuous buildings such as industrial warehouses and farms to give plausibility to their close proximities; these bases are usually separated by a neutrally themed space.
The game was released on October 10, 2007, both as a standalone product via Steam and at retail stores as part of The Orange Box compilation pack, priced at each gaming platform's recommended retail price.
