Path of the Deathless - Climbing to the First Base Camp

Continue through the archway.

Follow the path to the bottom, jump across the gap, and climb the rough wall until Lara is hanging from the edge of the stone walkway high above.

Climb along the wall to the left as the Deathless army begins to file past above you.

Jump past the broken section and continue climbing to the left.

At the end of the wall, jump to the left and latch onto the ice wall with your axes. Then climb to the ledge above on the left.

Move forward to the edge of the crevasse and jump toward the ice wall ahead. If you press Interact, Lara will latch on briefly, but then the wall collapses.

Lara tumbles into the crevasse but manages to wedge herself into the crack to stop falling. Press Jump a few times to work your way up the walls and latch on with your axe.

Then press Up/Forward to work your way through the crack to the other side.

Lara falls out of the crevasse into a dimly lit tunnel. As you follow the tunnel, you'll find a a few supplies on the way down. (In my game it was cloth, magnesite, and herbs, but some of these pickups seem to be random.)

Move down to the corner of the building at the edge of the canyon and climb the handholds to the top.

Climb around the corner to the left. Then continue climbing along the side of the building and out onto the wall of ice.

Jump straight up at latch onto the ice with your axes. Then climb up onto the long, horizontal ice formation.

Turn left, walk to the end, and jump to grab the mouth of the giant statue. Climb around to the left...

...until you can drop down near the Hall of Guardians Base Camp.
