Shipwreck Beach - Climbing the Cliff to the Research Base - Part 4

When Lara drops off the zip line, move forward, pick up some shotgun shells and scramble up the wall to grab the pipe above. Climb around the corner to the right.

Continue traversing to the right along the broken pipe, jumping across the gaps when you come to them.

Just before the end of the pipe, jump straight up to grab onto the yellow ladder. Climb to the top, jump straight up once more, and use your axe to latch onto the climbing wall above.

Continue climbing to the top of the wall to find a salvage crate. Crack it open.

Then take a running jump to the ledge below on the left.

When Lara lands here, she hears a couple of Mathias's men talking above. If you aren't in the mood for a confrontation, you can scramble up the wall...

...and crouch behind some boxes until they finish their conversation and move apart. Then kill each with a silent headshot. If either of them spots you and calls out, 2 more enemies will drop down from above.

Afterward, move out, loot the bodies, pick up a box of rifle/SMG ammo and then scramble up the wooden wall in the corner to grab the pipe above. Climb around to the left and jump onto the climbing wall. Scale the wall to the ledge above on the left.

Cross this ledge to the anchor post.
