Kinshasa: Secret tool
At the beginning of the mission you must go up a elevator. You will then get a checkpoint. When you enter this room, take
out the guards. Make sure you are not wearing your sunglasses. When you walk in the next, big, room, the sun should be shining in your eyes. Flip your glasses down and you can see guards shooting out the windows you were looking at. Go to the right as soon as you walk in. Try not to draw too much attention. If you keep going to the right you will hit a window. An icon should appear at the bottom of the screen, indicating that you can use something. Press X and Sam will get out a small black tool, clip it on the window, whiz it around, then pull off a small circle that he has cut from the window. If you push forward on the window, Sam will put his legs through and squeeze through the hole so that he is now outside.
