Grand Theft Auto: Chinatown Wars

Complete dropping off 15 people in a row without the timer running out and all taxi's will become bulletproof while you are in them. This will not affect number of times cheated in the stats menu.

Take a boat ride to any corner of the map to be greeted with a "Here Be Dragons!" message on the ocean floor.

This glitch lets you skip the hotwiring process of a taxi, and to do so you must find a taxi with no one in it. When you find it, get in the car and the hotwire process will start. Instead of hotwiring it press the SELECT button to start the taxi missions, then press SELECT again to cancel the mission. After this you do not have to hotwire the car.

Achieving certain tasks will reward you trophies, which can be found on the Trophy Shelf in your apartment.
