The aim of Spy Hunter is to drive around the highway avoiding a collision with all other cars. If you collide then you will lose health. There is also a hitman driving around that want to kill you, he will shoot your car and take of 10% health every time he does so, so you have to destroy him first, but if you do manage to kill you you will receive 500 points! It's no easy task though as his car is heavily armored, and if you crash into him you will blow up.
