Black Gold

After exiting the helicopter, make your way northwest of Delta Camp to meet Sam.

You will drive while Sam takes the gunner position. Your objective is to blow up 4 areas with planted C4. You have 20 seconds to escape the blast area after planting each charge.

Start with the southeastern C4 spot, located in a long fenced-in area. Kill the two normal enemies and the Heavy with an LMG, then plant the charge and escape, killing any enemies that appear on your exit.

The next C4 spot is the northeastern one. Be cautious as there is an enemy with an RPG nearby. Approach the reserve, and some normal enemies will appear. Go around the fence at the east end to find the path to the C4 spot and a Heavy with a Flamethrower. Eliminate him, plant the charge, and escape.

The next C4 spot is the southwestern one. Kill the enemies around the building, then go around the east side to the back to find a ladder. Climb the ladder to reach the window of the building where the C4 spot is. There are many enemies inside, including a Heavy with an LMG. Clear the enemies, then go down the stairs near the window you entered. Plant the charge, and exit the building the same way you entered.

The last C4 spot is in the north.
