Last update: 11 May 2016
Reach the exit of the ventilation shaft and jump down to the room directly below. Don't attempt to approach the terrorists in the area and jump into a larger hole straight away. This way you will start your march along the underground tunnels. The linear corridors will take you to a small room with a door. Turn off the lights, open the door and wait for the enemy in front of you starts moving away.
Follow this enemy and dash between covers to avoid the well-;lit part of the corridor. The followed enemy should enter the nearby control room. Don't enter there and, instead, grab onto the pipe under the ceiling. Shimmy to the right and wait for the remaining two enemies to scatter. Quickly, jump down and go to the neighboring room to the left shown in the screenshot.
Start hiding behind covers and move in a straight line. Watch out for the guard patrolling the area on the left. After you reach the wall, turn left, wait for the abovementioned terrorist to move away and open the grate that leads to the next ventilation shaft. Walk through the tunnel but don't hurry with leaving it because there may be enemies around.
You have to make the next move after one of the terrorists goes right. At the same time, make sure that nobody is looking your way. Leave the shaft and go right also. Position yourself, more or less, parallel to the guard and wait for him to turn away. Quickly, approach the objects in the right corner, shown in the screenshot, and hide here. DON'T try to go towards the exit straight away because there will be an additional enemy to come here on the elevator, and he will position himself in the corridor.
Remain behind your cover until the last one of the abovementioned enemies returns to the elevator AND uses it (you can't emerge from behind your cover too soon because, waiting for the elevator to start, the terrorist will be facing outside of the elevator. Go to the left, or to the right of the elevator that is inaccessible for Fisher and, by using the ledge, make it over to the ledge above. As you probably noticed, there are balconies here and it is thanks to them that you will come closer to the mission's objective.
After you reach the end part of the balconies, grab onto the red pipe under the ceiling and then, onto the horizontal ledges. Thanks to them, you will reach the balcony above another shaft with laser traps. Just like earlier, you first need to slide down at the right moment. Grab onto the ledge located below and shimmy to the right. Make another stop where you can make it to the other end of the horizontal beam.
Resume shimmying over the horizontal ledges and reach the corner, where it is possible to jump towards the interactive elements below. Don't forget about avoiding the lasers in the meantime. Go now towards the area marked by the game inside the vertical shaft, which has been shown in the screenshot. You need to press the interaction key/button here, thanks to which Fisher will hack into the net port.
