Grand Theft Auto III Cheats

While not doing a normal mission, get into a law enforcement vehicle (Police Car, Enforcer, FBI Car, or Tank) and press R3. In this mode you must chase down criminals and kill them.
Kill 20 criminals on each island and you will be rewarded with a total of 6 Police Bribes at your save point (1 for each set of 10 killed. You must kill criminals on every island to receive all 6 Police Bribes, however. This means killing 20 criminals on each island. Killing two sets of 10 criminals (20 total) in Portland will give you all the Police Bribes (2 total) you can get from that island, and so on.

NOTE: The criminal kills do not have to be done consecutively. Just be sure to kill 20 on each island while in Vigilante mode.

The longer you run the longer you can run without taking a break. But if you continue to tap "X" over and over again you can run forever and gain your stamina to the max.

Damaged vehicles can be repaired free at any hideout by parking the vehicle in your garage and get out of the car, leave to let the door close then return and any cars in your garage will be repaired.

Get a normal car and cruise the streets until you find a hooker drive up next to her (make sure she is standing next to the drivers door) and she will talk to you for a couple of minutes then she will walk around to the other side of the car and get in. Drive to a dark place (an alley, your hideout etc.) and park the car but do not get out. The car will start shaking and your health will go up. Then you have two choices:
1)Stay still and let her get out then beat her up to get your money back, or
2) tap the gas right before she gets out then park the car and watch the car start shaking again which saves time since it costs a dollar a second when she is in the car.

While not doing a normal mission, get in a Fire Truck and press R3. There is a Fire Station on each island. Put out 20 fires on each island and a Flame-thrower will always appear at one of your three save points.

NOTE: The fire missions do not have to be done consecutively. Just make sure you have put out 20 fires in each area.

After you pay to repair your car in the Pay 'N Spray, drive back in and you can get a free paint job.

When not going through a normal mission, get in an Ambulance and press R3.

Save 35 pedestrians and a health refill will appear outside any of your save points.

Save 70 pedestrians and an adrenaline pill will appear outside any of your save points.

Complete the Ambulance level 12 and Infinite Run will be granted.

NOTE:You do not have to save the pedestrians consecutively. You can do it as you go through the game.
