As soon as the level begins, get in the car and go to the nearest vehicle, or you can simply drive to the edge and slowly drive off it and land in the water. Then, climb up the ladder and follow the edge for a short distance. On your left, you will see several men with machine guns as you proceed forward. Shoot them around the corner of the wall, being careful not to fall off of the rim of the dock. If you fall in the water while trying to get back on the rim, you must go back to the ladder that you started from. Continue through the path until you get to the part where the car is located. Shoot all visible enemies then get into the car. Look at the map and drive forward to the point of the dock and get into the water. There are enemies on the dock that will fire at you. Swim as close as you can to the yacht, and go around the left side of it to the ladder leading to the dock. Once there, it will be much easier to drive to the goal or just explore the world. Note: The boat will glitch if you take it to the goal and freeze the game. If you are tailed, drive your car into the water and they will follow you. They are much more defenseless while treading water, and their passenger will automatically go down with the wreck.
