Reach the basement level of the parking lot | Mission 6 - Special Missions HQ Splinter Cell: Blacklist Guide
Last update: 11 May 2016
Also here, you should take your time, because there is another camera above the entrance to the parking lot. After you go past this one, you should turn right and wait until the guard that you can see in the distance goes left. Go where the enemy used to stand, make sure that the camera rotated to the left, climb onto the elevation and hang down at the edge, quickly.
You can now zip the line. You need to stop in the spot shown in the screenshot. For obvious reasons, you need to wait for one of the enemies to turn away. Only then, finish sliding down the line to reach the basement level of the parking lot.
Remain in the spot where Fisher released himself from the line and wait patiently for the general to fob off the next enemy. Only then, jump over the wall and follow Rohani. I accordance with the game's suggestion you need to remain very close to the general because he is the only one who will allow you to avoid laser traps (it is good to know that interfering with the laser beam results in the raising of the alarm). Soon, you will reach the prison and the game will display an interesting cutscene here. From it, you will learn that you have been driven into a trap.
