Instructions
Travel to the docks in the "Little Haiti" section of the map and meet Lance. He will start a fight with a group of drug dealers as you arrive.
Attack the drug dealers and help protect Lance from fire by using your gun. Use the left trigger to aim the gun and the right trigger to shoot.
Enter one of the two trucks and follow Lance, driving ahead of you. Press the "triangle" button to enter the truck, the analog stick to steer and the right trigger to accelerate.
Avoid the rockets launched by the truck following behind you as you drive on the South bridge. Alternate between driving on the left side and right side of the bridge to avoid fire.
Continue following Lance, who is leading in a car in front of you, and avoid the police behind you. When Lance arrives at his location, the mission is complete and the second island will be open for new missions.
