Spy vs Spy is a strategy and action game for the Game Boy Color, featuring the ongoing rivalry between the black spy and the white spy. Players navigate through an embassy, searching for essential items such as money, passports, and secret plans while setting traps for their opponent. The objective is to collect all items, place them in a briefcase, and reach the airport door before time runs out.
The black spy and the white spy are out to outsmart each other before the time bell rings. Find the needed objects (money, passport, secret plans and airport door key) by searching rooms in the embassy, which include desks, file cabinets and other furniture. Foil your opponent by setting creative booby traps in the various rooms (a bomb in a dresser drawer, for instance). Traps can be disarmed with objects found in rooms (a water bucket from a firebox on the wall will disarm the bomb in the prior example). When all the items are together in the secret briefcase, head for the airport door.
