In San Andreas go to East Richman and get in a green penatrator and just press accelerate. You will get an insane stunt bonus.

In Liberty City, do the mission where you have to pick up a man in the taxi. Before you pick him up, get the taxi resprayed in the respray shop by the park. The taxi will now change into a really cool green taxi.

On the mission where you have to get the motorbike from the Angels, get the bike and all that, but when you got to drop of the drugs for Tommy, wait until he starts WALKING, and run him over, you get TWO mission completes, and the multiplier goes up by two.

If you find two tanks, you can drive one on top of the other.

When you're in a wrecked car, STOP the car because if it isn't completely still, the cheat won't work. Get out, and then get back in again. The car will have its original performance, and still make the noise. If you so much as tap a wall or anything, the car will be wrecked again. Now you can drive as fast as you can into another car, blowing both of you up. This is great in multiplayer.

Well its basic who wants to know where the tanks are. In Heist All Mighty, there are 3 on in the dome thing in north Fort Law and two parked side by side in northwest Estoria. To find them, look where Estoria connects to Law Island and follow it up. To find tanks in San Andreas, follow the big red bridge to the south end and go right throught the trees and grass and round the bomb shop and go straight up to find the hole in the building and drive throw and just keep going off the end to the island where a tank awaits. In Mandrin Mayhem, only in Vice City the bottom of Vice Beach is a curious island with nasty military blokes and a tank inside. To turn a tank turrent you need to hold down the Tab key and use the steering controls.
