Detonate the EMP charge at the fuse box | Mission 4 - Private Estate Splinter Cell: Blacklist Guide
Last update: 11 May 2016
Since you have already had experience with the Trirotor drone, the basics of operation should be known to you. Start the very linear flight, during which you do not need to be too cautious. After you reach the vertical shaft, press the ascend key/button, thanks to which you will be able to continue the flight. Stop the drone only after you come near the room with two guards in it. Approach the right wall and fly up to the hole in the floor shown in the screenshot.
Wait for the enemies to walk away and, only then, fly through the abovementioned hole. Stop the drone again and ascend until you reach the recess shown in the screenshot. Fly over to the other side and do not stop anywhere on your way, to prevent the drone from being spotted by the guard sitting on the chair.
Fly past the guard mentioned earlier, around the back, and fly into the neighboring room before his colleague returns here. Stop opposite the fuse box, shoot out the charge and detonate it. This will result in the power being cut out around the entire estate. As a result, you will be able to implement the main part of your plan and set out for Nouri.
