Last update: 11 May 2016
As the mission begins, run after Marinov to the nearby building. Right behind the corner, wait a bit for the guards to stop talking and when Maddox gives the order - lean out and take out the soldier in the neighbouring room.
Move onwards and eliminate another soldier with a knife or silenced pistol on your way. After reaching the next room, sneak to yet another enemy and kill him as well.
After reaching the mezzanine, you will see an enemy in the next room. Don't kill him, instead head to the upper floor - from there you will be able to easily kill the enemy on the upper floor. Use a silenced pistol to do it quietly.
Head to the lower floor and follow Marinov to the next floor.
SECRET 1/4 - In the corner on the other side of the room on the floor where Marinov suggests heading one floor higher.
Eventually you will reach the third floor - silently kill the guard by the window and a cutscene will activate.
You need to make four photos - move the camera across the whole area and search for places where the markers turns green.
