Siberian Wilderness - Defeating the Trinity Scouting Party (Part 3)

After taking out the first three Trinity scouts, as shown in the previous sections, continue downhill toward the monolith and the abandoned encampment—not so abandoned now. Circle around to the shallow trench below the fallen log.

From here you can spy on the 3 men at the camp. Notice how they glow red in Survival Instinct. This means if you attack one of them, the others will notice and come after you.

If you wait patiently—or shoot an arrow into the wall near the monolith to get his attention—one of these guys should wander off away from the others. He'll then turn white in Survival Instinct view.

Now you can take him out with a silent headshot: Hold Aim to draw the bow, zoom in by pressing the right stick or Z, adjust your aim, then hold the Fire button to charge the shot for more power before finally releasing the Fire button to shoot.

Now move cautiously forward into the bush near the camp.

Target one of the 2 soldiers.

And press RB/Middle Mouse to fire a poison arrow. The toxic cloud should then kill both of them. You can also shoot the gas generators to blow them up, injuring nearby enemies in the process. Needless to say, your cover will be blown if you do this, and you'll need to fight any survivors.

The last man is patrolling off to the left.

You may be able to shoot him from here. Otherwise move forward, using bushes and trees for concealment, until you find him. Since Lara is still fairly underpowered compared to her enemies, I recommend using stealth if possible, rather than confronting him.

When the last enemy is dead, Lara will stand up and stow her bow, showing the coast is clear.
