The Gulag - Shacks and Flooded Trenches

After obtaining the ASSAULT RIFLE and killing the first 3 Trinity soldiers, as shown in the previous section...

...advance cautiously and take out 2 more Trinity soldiers in the shack ahead on the left. If you stay under cover, the first man should come to you.

Then move up to the doorway of the shack and kill the guy inside.

Search the bodies and pick up rifle ammo and herbs for bandages inside the shack.

NOTE: If you've been using stealth attacks up to this point, you may not have needed bandages, but you probably will here. Just as a refresher, healing requires herbs (available from bushes with red berries and from containers and baskets like this one) plus cloth (from searching dead enemies and occasional crates/containers). To use these ingredients, hold LB/V to make and apply a bandage. If you unlock the Brawler skill Fast Healer, Lara can do this more quickly during combat.

Lean out the next doorway just far enough to kill the next enemy lurking behind a box ahead on the left.

Then move out a little farther to shoot his comrade.

Or, shoot the lantern to kill the first man with fire.

Then shoot the second when he pops out from behind the barricade near the next shack. Loot the bodies and pick up a chunk of magnesite ore lying on the ground (circled in the screenshot above).

When you enter the next shack, 2 more enemies appear ahead. Stay partially concealed behind the cable spool to the right of the doorway and shoot the red fuel barrel at the back of the room.

The resulting explosion should kill both men. If not, finish them off before advancing. Loot their bodies and pick up more rifle ammo and magnesite inside the shack.

As you emerge from this shack into the waterlogged trench, a brief cutscene teaches how to make SHRAPNEL GRENADES. press Interact to pick up a tin can. (Here Lara has already done so during the cutscene.) Then hold RB/Middle Mouse to combine it with magnesite ore to make a grenade.

Hold LT/Right Mouse and use the right stick or mouse to aim at one of the 2 soldiers. Then then press RT/Left Mouse to throw the grenade. Boom!

Craft another grenade the same way or just shoot the second guy.

Craft another grenade and wait for a third man to come out of the shack.

Toss the grenade at him.

Then, if it doesn't kill him outright, run over and finish him off with a gunshot or melee attack (Y).

Loot the bodies and pick up a lump of magnesite and some salvage on the wooden deck ahead on the right.
