Geothermal Valley - Occupied Village Middle Level (Part 3)

Loot the bodies and examine the document (22/33) on the crate. It is Forgiveness from Konstantin's Operational Report series. There's also a strongbox (8/8) just to the left of the shelter. It contains a FULL-AUTO SHOTGUN PIECE (2/4).

NOTE: There's a survival cache buried off to the west, but a spiked wooden barrier prevents you from reaching it right now. You may also notice some glowing barrels if you activate survival instinct. These are part of a later challenge.

Climb the nearby tree and jump onto the roof of the shelter.

From here, you can leap onto the wide ledge above and behind the shelter.

There's another document (23/33) here, On Bears from the Ways of the Valley series (Greek), and a flammable barrier, concealing a cave. Inside you'll find a nice cache of supplies, as well as another document (24/33) written in Greek. It is The Sermon from the series called The Apostle.

Exit the cave and head down the hill to the left (east).

As you re-enter the area near the campfire, a single Trinity soldier (mentioned earlier) comes through the building in the northeast corner.

If you stay hidden, you can take him out as he moves toward the campfire to survey the carnage. If he does notice Lara, it's not a big deal since there's nobody close by to answer his call for reinforcements.

At this point, you can take as much time as you want to scour the area you've already cleared for ammunition, salvage, and other supplies. When you're ready to move on, go through the ruined shack where the last soldier came from. (Follow the Survival Instinct beacon if you get disoriented.)

Pick up another document (24/33) sitting on a box inside. It is Initiation from the brilliantly creepy Heart of Darkness series. Then continue out the other side of the shack and up the path to the next area.
