Go to Airport D' Nice parking lot. In there, you should see an underground parking lot, but don't press the switch though. Instead, go to the grass, but don't run, walk. You'll fall down and it'll sustain damage if you don't have an Invincibility cheat on. You'll fall down for a few minutes, then land on an invisible floor. You shouldl see a city that it's above you. walk or run your way out of the glitch. Once out of the glitch, you'll be on top of the city in a flash, so it does'nt affect your saved file. If you're driving a vehicle and end up in the Abyss, the vehicle explodes, causing you do die, so bail out of the vehicle fast or end up in the abyss.

Enter the invincibility code, get a car, shoot the car until it starts to flame. Get in the car before it explodes, then drive off. The vehichle will not make any sounds except the horn.
