Grand Theft Auto III Cheats

Whenever the moon is visible at night shoot it with the sniper rifle to make the moon bigger or smaller.

On the second island (Staunton Island), go to the left of the main entrance of the car park that was used in the Kingdom Come mission. Go up the stairway you find up the alleyway with a car and park the car by the wall to the right. The wall is too high to jump on so you will need the car. Jump on the car, then on the wall and you will be on a flat roof. Jump off the wall to the area where you see all the metal fire escape stairways and look around. You will then see a message on one of the walls that reads: “You werent supposed to be able get here you know”.
