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

Press the START button, go to the Audio menu, select the station you want to reset, then press the START button and press left or right to change the menu while the pause menu dissapears. For some reason, the radio station you selected will reset. You will notice the station track reset if you are in a car.

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.

Take an ambulance to the top of Marco's Bistro in the St. Mark's area. It takes a bit of work, but you should be able to get it up the stairs eventually. Now, slowly back it up so that it almost rolls over the edge of the little wall, but not all the way. Now (quickly) find a car on the street and bring it in front of the ambulance so that you can jump on the ambulance's hood and then roof. While on the roof, jump towards the brick wall of the building. You should end up on an invisible ledge or roof and you can run around quite a large area before the invisible ground ends. Tip: Use a gun that you can aim manually to shoot the "ground" in front of you a bit. If there are sparks, then it's safe to walk, and if there aren't any than you will fall if you try to walk there.

Get into a taxi, hold down the R3 button. Exit the taxi and step into another car, release the R3 button and you should be able to do taxi mission in the car you are currently in.

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 (2total) 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.

You need a saved game for this. Start a new game, and after the beginning cutscene load your other game. You'll have everything, but you'll still be wearing a prisoner outfit.
