In the cutscene, you will find yourself separated from Chase by a pickup truck hurtling out of control. You will have to meet up with her again to continue. Run through the small opening under one of the houses and climb the pipe to reach a blue-barred window. Climb up the window to get to the roof. Walk across the plank to reach the next roof. You’ll have to balance halfway across the plank as an explosion shakes the compound. Climb up the window and loop around the front of the building. Be ready to swipe upwards on the screen as you transition from the side to the front of the building, as another explosion will destroy the pipe that you are climbing on.
Climb onto the next roof and up the pipe. Navigate over the window to the wooden outcroppings, which you can monkey-bar across. Jumping off to the other side will reunite you with Chase. Follow Chase to discover a dusty old trowel. Drake will pick it up and you will have to dust it off using the touch screen. After that, move to the next area to encounter a group of enemies. You can tackle this section stealthily or with a firefight, but it’s easier to go the sneaky route. Quick timing will be required to complete this section unnoticed, however.
Run up to the cover behind the first enemy and reach over the cover to knock him out. Stay in cover. The second enemy will patrol back and forth ahead of you. Follow him into the corner and take him out too. Quickly run up to the third enemy before he turns around and knock him out. If you’ve timed it quickly enough, the fourth enemy will be here also. Follow this up with a fast attack and he will be taken out silently, clearing the path ahead. If you are not fast enough, however, the fourth enemy will have made his patrol already and will be positioned at the top of a ridge to the right. In this case, there is no way to kill him stealthily, so get behind cover somewhere and line up a headshot on him. Dig into cover to deal with the reinforcements that will arrive, one of whom will be wearing heavy armor and wielding a shotgun.
Run up onto the ridge after dealing with all of the enemies to discover a treasure. Pick it up and loop back to where Chase was hiding. Facing her cover from the front, turn to the right and run down a small path behind the first house. Next to a large fern, you will find a charcoal etching jutting out of the ground. Proceed to the back of the area and climb up the ledge to initiate a cutscene and end the chapter.
