Siberian Wilderness - Gathering Resources and Crafting Arrows

Head downhill toward where you found the wood and deer carcass earlier. Use Survival Instinct to spot a few useful items: a bird's nest and another sapling.

Now hold LT/Right Mouse to draw your bow. You'll see an on-screen tutorial about charging your shots for extra damage. This isn't necessary, since the nest is not trying to harm you, but can practice if you like. Continue holding LT/Right Mouse, aim at the bird's nest with the right stick or mouse, then hold RT/Left Mouse to charge your shot. You'll notice Lara can only keep the bowstring taut for a little while before she has to let the arrow fly. Later you'll upgrade both the weapon and your skill with it, so this won't be a problem. For now, you can either release Aim to cancel the shot or release Fire to shoot. When you're ready, shoot the nest to knock it out of the tree.

Find the nest lying on the ground and press Interact to pick several feathers out of it.

Along with a notice about the feathers being added to your inventory, you'll see a message about using them for crafting.

Move to the small tree you spotted a minute ago and press Interact to gather more hardwood.

Now, without drawing your bow, hold RT/Left Mouse to craft arrows from the wood and feathers you just found. The amount of resources expended is shown on screen, and the new arrows are added to your inventory.

Unlike Lara's pistol ammo in Syria, you do not have unlimited arrows and must find or make them for hunting and combat. We'll practice hunting shortly, and later we'll cover other items you can make from gathered resources.

NOTE: I do not list the location of every collectible resource in the walkthrough. These don't always appear in the same places and will respawn if you leave and re-enter an area, so Use Survival Instinct to spot them and harvest them as needed.
