Go down the steps to begin another stealth section. Jump down and take cover behind the first guard to take him out over cover. After this, there will be two guards to the left and one guard on the right. Head left first. Loop around the boxes in the middle to get behind the closest guard and take him out with a stealth kill. Then climb up the ramp to get behind the second guard. Move over to the right side of the room now. Follow the guard into the corner and take him out when he stops moving.

Now run into the little square are in the top left and take a picture of the map on the wall. Then head to the back of the area, on the ramps where you took down the second guard. Head to the end of the path to find a treasure between two rows of hay bails. Once you’ve grabbed all of the goodies, head to the door on the other side of the room and help Chase pry it open using the touch screen. Look immediately to the left to find a treasure sitting on the table. Pick it up and run into the small courtyard in the top left of the area to bring up a photo icon on the side of the screen. Tap it and take a picture of the graffiti-covered sign to get a secret.

Leave the room and head to the left to find Chase in cover. Jump over the two barriers and go left into the clearing. Two enemies will be waiting for you. Don’t even try to bother with stealth, just shoot them. Approach the lift for a cutscene. Afterwards, climb the pipe behind you and Drake will pick up a wanted poster when he reaches the top. Just like before, you will have to piece the shredded poster together by rotating the pieces on the touch screen. The shapes are all pretty distinctive, so it should be easy to see which goes where.

Climb onto the grey pipe and jump right, then climb up and back around left to hang off of a sign. Swipe upwards as you are curving back to the left to avoid death as the pipe collapses. Swing across the monkey bars and drop down behind the enemy. Stealth kill him and run down the path to push another enemy off of a ledge. Walk across the tin beam here and curve off to the right. You will see a bunch of yellow pipes on the wall to the right above the electrical fuses. Climb them to initiate another cutscene.

After the cutscene is over, jump across to the other side and pull the guard off of the ledge. Walk to the lift for a short cutscene, then jump across the gap to land on the counter-weight. Drake’s weight will be enough to raise the lift. Climb up on the makeshift ladder of yellow pipes to get back up to the top. Chase will be waiting for you here. A cutscene will trigger and the chapter will end.
