Mountain Temple - Climbing to the Upper Level

Follow the path to the right, picking up some pistol ammo lying on the ground. When you come to the edge, jump across the gap to grab the wooden structure ahead. Climb around to the right...

...then up to the level above. Go carefully, though, since there are 2 enemy archers up there.

Stay behind the crate as you take out one of the men with a silent headshot.

The other one will notice when his comrade falls, but if you act fast, you can shoot him before he can do anything about it.

A ladder drops from the cliff above, and a third soldier starts to climb down. Shoot him as he descends and he'll fall to his death.

Loot the bodies for spare arrows and salvage, and pick up pistol ammo, more arrows and a food cache lying on the ground.
