Spy Hunter is a vertical scrolling driving game with the player in the role of a spy driving an armed sportscar. The object of the game is to travel the freeway destroying as many enemy vehicles as possible while protecting civilian vehicles. The game uses a top-down perspective.

The game begins with the player driving the fictitious G-6155 Interceptor. Various enemy vehicles try to destroy the player’s car or to force it off the road, including a helicopter that drops bombs from overhead. A counter increments the score while the car is moving and on the road. Additional points are earned destroying enemy vehicles using weapons or by forcing them off the road. After an initial lead-in time during which the player has an unlimited supply of cars, the player must earn extra cars by obtaining sufficient points.
