Total Overdose: A Gunslinger's Tale in Mexico Cheats

If you steal an occupied cab (the ones that offer to take you from city to city, no matter the car model) by shooting the driver and taking it, the cab will be indestructible while you are in the driver's seat. Even if the cab takes damage while you are out of it, it will still remain indestructible once you jump back in it, even it is has cosmetic blemishes or broken windows. However, if you wander too far away from the car, a taxi driver may re-appear in the driver's seat, but the cab will be where you left it. You will have to kill the driver again if this happens.

Find a car driving the street, jump on the car and let in drive till it reaches a good speed (you can shoot in the air to make the car drive faster), after you are at high speed shoot a cop to make your adrenaline meter visable, then do a slow motion shoot dodge, after that you will notice the driver in the car will be out of the car and the car will drive without a driver, you can enter it and it will be bullet proof!
