Meet up with Briggs at the boat | Mission 8 - Detention Facility Splinter Cell: Blacklist Guide

Path at the cliff

The final part of this mission is a mere formality. On your way, you will meet no opponents. Go towards the cliff and take the narrow path that is running next to it. During your march, you will have to do some rock-climbing, but all of this is a piece of cake. Reaching the boat is equal to completing the mission.

Quite exceptionally, this time you won't return to the airborne command center and, after you finish this one, you will have to play another mission (Airstrip). This one involves fighting back hostile mercenaries in wait for the arrival of the plane.
