As soon as you enter Free Ride mode, you will start in a car with a reddish gate directly behind you. Drive forward so that you are in the street, then reverse right back to the location you started. A car selection screen will appear, and you can select any unlocked car.
Kill the men in the all black suits with the black hat (gangsters) to earn $500 each. Go into the country and speed in a fast car. Blow up cars for $100 each. Drive taxis to earn money.
Aim at the tires and shoot where the bolts are, in the middle. This works best with the Tommy gun.
While driving through the city, you will encounter many police officers. You can run one of them down and pick up his standard issued gun. Your wanted level will go up, but immediately diminish. This works best if there is only one police officer, on foot, with no police officer witnesses.
Walk behind them and shoot them. This works best with the sawed off shotgun.
Get to a rail station, elevated rail station, or trolley. Get in and wait until your wanted level goes down. The most efficient way to evade the police is make a lot of turns. The best turns are in front of or behind another car or the trolley. The police will try to make your exact turn, but will run into the car or trolley. You can also make turns between light posts close to the curb if your car is small or short enough. This also works well during the first mission.
If you have a gun and the cops are after you, you can get rid of them by shooting them. This takes some practice, but it can be done. You have to be on foot. Shoot both cops until their weapons fall. Head shots work best. If you manage to kill both advancing officers, you will no longer be wanted. This works best if there is only one car after you (the offense does not matter). The more the cars, the more difficult it is.
When you first start driving, go all the way down the road and take a right. Follow this road. This will lead you to where there is only a right turn. Take the turn. Looking left, there seems to be a small barrier blocking the ocean. At the beginning of the turn there is actually a hidden bottom where you can drive. If you slow down to about 50 or 60 miles per hour, drive over the barrier. By going slow enough, you can land at the bottom drive part. The enemy gangsters will not slow down. They will follow you over the barrier. If they have the correct angle or speed, they will fly into the ocean or land upside down. If you have not gone over the ocean or flipped over, there is a ramp where you can escape the gangsters and finish the level. Note: This may require a few attempts.
You can save some effort by shooting the tires on the getaway car before you try to enter the hotel. It is much easier than trying to shoot them while driving at the same time.
Your objectives in this mission are to kill the manager; tell the whore to leave town; and place a bomb and documents on the desk of the director's office. First, tell the whore to leave town. However, to do so, you walk in a lobby of a hotel without having any weapons out. There will be two security guards with weapons. When you walk in you will see stairs and the sign on the desk. To your right will be a doorway. Go through it and take a left without going into any doors, then take a left. Enter the first door on the left. There will be steel stairs for every floor. Go to the third floor. Take a right down a hallway. It will have a plant in the corner. Enter the first door on the left to find the whore. Then, go back down to the lobby. You cannot have any weapons out the entire time. When you are in the lobby, go under the stairwell in the corner where no one can see you. Press Up to take out your weapon. Then use the Right Analog-stick to aim at the person behind the sign at the desk. Kill him and the two men that will come up to you. After killing them, go behind the desk and enter the back room. There will be a green arrow pointing at a key. Press A to retrieve it, then go back to the steel staircase. Go to the top floor and take a right. Go down the hall half way until you reach another lobby. Kill the man on your left, then go to the other side. You will be facing a door with one on your left with the sign directory. Go in and kill the man in the black suit first. Then, kill the man in the white suit. After doing so, go in front of the desk and press A. After that, leave the room.
When you enter the dock, get a truck and drive to the other entrance to the harbor. Nearby, there is a house with a man. Kill him. He has a US rifle, which you should use to shoot the round fuel containers near the crane towers. The snipers will not shoot you, and you will get to see a really great fireworks display.
When you have to take Pauly to kill Segerio Morello and must escape instead of running, get out of the car and kill all of your enemies. Search all their bodies. From one of them, you will get a Thomson 1928 which is useful at the harbor.
