Spy Hunter is the NES port of the arcade game. It is a driving shoot-em-up meant to simulate a get-away chase. You will face traditional "spy" enemies on the road like tire slashers, bulletproof bullies, limos who shoot at you, and helicopters who drop bombs on you. You also get equipped with powerful spy gear like machine guns, smoke screens, oil slicks, and missiles.
