Black Gold | Main missions Far Cry 3 Guide

Reach the designated rendezvous point with Sam. Pick up speed on the car and drive into the camp, and towards one of the four designated targets. Each one of them is heavily guarded by enemies, including the armored ones. Do not worry too much about the enemies outside of the building/structure, Sam will handle them. If you notice his health bar going too low, help him. After you plant the explosive and drive towards the remaining targets. The guards in your way can be ran over.

After you destroy all four targets, tables will turn and, you will have to cover Sam, using the car-mounted machine gun. Take advantage of the explosive barrels located here and there, to kill large groups of enemies. Focus your gunfire on the RPG-wielding mercenaries, as well as on other vehicles. Once Sam returns to the car, you will drive out of the camp, which will make the mission complete.
