Fortress Tower - Climbing Out of the First Tower

After Lara drops down into the building from the Solarii Fortress level, a demolitions man drops a fire bomb into the room and scampers away. The flames start to spread. Time to escape!

You don't need to move frantically, but don't hesitate or the flames will catch up with Lara. Start by climbing onto the ledge with the fluttering cloth banners. On top, turn right.

Then take a running jump to grab the planks on the wall ahead.

Climb to the right. Then jump right and press Interact to latch onto the rough wall with your climbing axe. Continue climbing to the right...

...then upward into the doorway.

Lara spots the helicopter in the distance and you receive 400 XP and a new goal. The floor behind you catches fire, so don't linger here. Jump and grab the zip line and slide down to the end of the wooden bridge below.
