The Outskirts: Outside

When you wake up, check the small table with the lantern in the other room to
find [TESS' LIST]. Go inside the other room, have a word with Tess, then
activate the generator in the hidden room by pressing triangle at the right time
three times in a row. Ride the elevator down and search the right side of this
room for the [PATROL ROUTES MAP]. Head through the tunnel and go up the ladder.
Outside, simply head through the truck up ahead to trigger a scene.

Move through the hole and hide behind the vehicle. Run and hide behind the
car to the left and from here, quickly drop down the trench. Dash towards the
end, then move through the sewage pipe and drop down. Hide behind the wall and
move left; you'll want to avoid being seen by any of the guards, and it'd be a
massive waste of ammo trying to kill them (which isn't possible, you don't have
enough ammunition for all of them). Stay out of their search beams and move 
close to the rock wall of the trench, then curve around the corner and make a
run for the second sewage pipe. Move through and quickly drop down to the left.

Quickly climb up and move to the right side before going up the hill to find
[(1/4) BLADES]. When you reach the top, hide behind the wooden planks and head
for the stairs. Drop down and hop through the windows at the end, then search
the desk to find [(1/2) BINDING]. Head through the garage door afterwards.

Move towards the car and sneak to the right side of the area. As you proceed,
one guard will start searching this section, so try moving behind him to perform
a stealthy takedown. Press onward and hide behind cabinets and desks, then hop
in the truck and make your way to the end of the street. Crawl through the
sewage pipe and follow the linear area until you reach a hole in the wall.

Continue down the hall and stay low on the left side. The room to the left, at
the end of this hall contains [5 PARTS] on a desk and [(1/2) BLADES] in one of
the lockers. Head down the other tunnel and you'll soon enough reach the next
area.
