Fortress Tower - Climbing the Tower - Part 2

Just as Lara is about to pull up, the wall collapses inward.

Lara manages to grab onto a to a wooden ledge inside the tower, but you must press Interact to keep from slipping.

Pull up and immediately run forward, jump at the edge and grab the horizontal beam directly ahead. This beam looks like it was originally part of a staircase.

Climb up until Lara is standing on top of the banister.

Turn left and move quickly and carefully along the beam. At the end, jump forward and grab onto the dangling crate full of dynamite. (Yikes!)

As you climb up the crate, it sinks under Lara's weight, and you must press Interact to keep from slipping. Once you've regained your grip, continue climbing to the top of the crate.

Then jump to grab the edge of the opening ahead and pull up as the crate falls away behind you.
