Remember the Aston Martin DB7 in the James Bond film Goldfinger? Well, Spy Hunter puts you behind the wheel of a car with missiles, machine guns, smoke and oil.
The idea of the game is to drive down the road shooting all the baddies and acquiring more weapons by 'docking' with a weapons van which will re-stock your supplies of missiles, etc.
Various baddies are blocking your way and trying to knock you off the road, you can of course knock them off as well.
Occasionally you can change your car for a boat where there are added difficulties of islanders and depth-charges.
The game is very fast and exciting to play, though it would be useful to have two stick down joysticks to play it as you need one to control the car and the other to control which particular weapon you are going to deploy next. A game well worth looking at.
