Spy Hunter

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. The car is equipped with a machine gun that has unlimited ammunition.
Various enemy vehicles try to destroy the player's car or 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 by destroying enemy vehicles using weapons or 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 reaching score thresholds. Destroying non-enemy cars halts the score counter for a short while, and no points are scored whenever the player's car is off the road. The car can be destroyed by a hard collision with another vehicle, if it is hit by an enemy weapon (including the craters blasted into the road by the helicopter's bombs), or by running far enough off the roadway (or waterway).
Following periodic forks in the road, the player can enter new regions with different terrain or weather conditions. The player can also acquire special weapons by entering a weapons van, which appears in each new territory and can be periodically summoned by pressing its button on the yoke when its dashboard light is flashing. Available special weapons consist of oil slicks, smoke screens, and surface-to-air missiles; each is controlled by a different button, and the dashboard lights indicate which ones are available at any given time. Special weapons have a limited ammunition supply and are lost whenever the player's car is destroyed.

At certain points, the player will have the option to convert the car into a speedboat for a brief time by driving through a boathouse; at others, the player will be forced to make the transition. Enemy boats can attack from in front or behind, and the helicopter can drop bombs from above. While in speedboat mode, the oil slick becomes a flamethrower, while the smoke screen and missiles remain unchanged.

The game has no ending, and play continues until the player has lost all cars.
