The Prodigal Son

Make your way to Fort Drubman, northeast of the Baron Lumber Mill, to find Hurk Drubman Sr. Agree to help him retrieve his truck.

Talk to his son, Hurk, and then ride with him in the car to the watchtower.

Once you arrive at the watchtower, get out of the car and head to the end of the overlook. Use binoculars to spot nine cultists, including two Marksman enemies at the top.

Approach from the bottom. Wait for the armored cultist to move left, then take him out and hide his body behind the rocks near the sign.

Eliminate the next cultist patrolling the lower area.

Look to the right of the sign for a path. Follow it around the outside to the back of the tower, avoiding the Marksman's line of sight, and dispatch the cultist patrolling there.

Continue edging around to the right side of the tower and eliminate the cultist on the corner, hiding the body behind the tower.

Return to the left side of the tower and wait under the stairs. Wait for the two Marksmans to move in opposite directions, then creep up and eliminate both.

Head back down the stairs and get behind the remaining three cultists for easy takedowns.

Before climbing the watchtower, grab the Med Kit and Body Armor from a nearby crate.

Wait for Hurk to use the zipline, then follow him down the mountain, ensuring you don't get too far ahead.

After reaching the last platform, descend the ladder and continue following Hurk.

When Hurk reaches the cabin, you will need to dispatch the enemies in the area. Stealth is not an option here as Hurk will immediately use his rocket launcher. Be quick to eliminate all enemies as they can summon reinforcements.

Hurk will take control of the truck, leaving you to operate the mounted gun on the back.

Deal with pursuing quads and pickup trucks.

As you reach the main road, a helicopter will appear. Use the radar (your minimap (the small circular map in the bottom-left corner of your screen) with nearby blips and threats marked) to locate threats and keep firing. The helicopter does not require many bullets to destroy.

Once the helicopter is destroyed, the pursuit ends, and you can safely ride back to Fort Drubman to conclude the mission.
