Open the Large Gate | 6: At An Impasse Walkthrough Tomb Raider Guide

Before proceeding to the task, it's a good idea to use the newly upgraded pry axe to open two previously locked boxes. You can find them respectively in the second and the third base camp, and each of them is worth 50 Salvage points.

Approach the mechanism at the large gate in the ruins. Start tapping the action button to open it and unlock further way into a new location, Mountain Temple (reward: 400 XP).
