The Gulag - Combat in the Prison Yard (Part 1)

From the starting position, pick up wood lying directly in front of you and craft as many arrows as you can.

You can take out the first 3 enemies without moving from this spot. Start with the one in the guard tower ahead on the right.

There's no hurry. Take your time and line up a headshot. Zoom in by clicking the right stick or pressing Z on the keyboard. Aim. Then hold RT/Left Mouse to charge the shot and release it to fire. Silent and deadly.

Now for the guy in the tower just to the left of the first man. Kill him with another well-placed headshot.

Your third target is pacing along the top of the cargo container on the far left.

Getting a headshot is challenging since he almost never stops moving, but if you can manage it, you may unlock the English Pedigree achievement for a bow-and-arrow headshot from more than 25 meters away. Otherwise use the rapid-fire technique you learned from the codex in the Ice Ship Challenge Tomb. Charge your shot by holding RT, release the trigger to fire, then quickly press it again for a second arrow.

Once the three spotters are down, strip the nearby sapling for more hardwood and then climb the ladder onto the roof of the next shack. Move to the right so the men below won't see you.

Loot the bird's nest for feathers. Then walk across the beam to the guard tower.
