Hints:

Bomb Shop

When you start out on a level steal a car, but don't pick a big one or else the trick will be harder. Then keep searching for a garage door kinda thing that has an X coming out from it. Enter that place and your car will be rigged or in other words bombed. Then stop the car somewhere and press the FIRE button your car will be armed so get out of it within about five seconds or you will BLOW up! This trick is useful for jobs, killing and collecting money. You MUST have at least $5,000 dollors or you will not be able to get your car rigged.

Easy Tank

On the first city, access the second scene (Heist All Mighty.) When you start, run somebody over and wait for the ambulance to arrive. When it does, nick it and drive to the army base, drive in and you can nick the tank. This only works with an ambulance or a police car.

Gang Leader

Go up to a group of Gurangas, or the groups of people making noise and running around following each other. Now, don't shoot them, but instead beat up the person in the front. If you beat him up enough, they will start following you almost anywhere. It's a good way to get a guranga with a machine gun, flame thrower, or other high powered weapon of death.

Train Hijacking

At any train station, enter the train and press CTRL to gain control of that train.

Walk in the Sewer

From the starting location, in Liberty City, go north on the starting road past the park, all the way until you get to the Beast, then go north on that road, around the bend until you get to the next major 3-way intersection. Take an immediate left on that major road. Go over the bridge and take a right on the road, heading north, immediately after it. Go past the Hospital and Police station, then take a left on that major road. Follow that road until you get to a 3-way intersection with a 6-lane road. It is the first sewer on YOUR right. Get out of your car and step on the curb next to the sewer, you should fall through. Once you fall in, you can't get out. Drive your car on it for a nasty surprise.
