Part 32

Stay to the right side of the corridor and shoot out the tube light on the wall halfway down, then shoot out the martini-shaped white light under the camera at the far end.

Switch back to normal vision.

Turn the NV (Night Vision) on again and slowly move down the hall to the end, stopping in the left-hand corner.

As you move down the hall, you will see an open door to the right of the camera leading to a lighted room with a terrorist.

When you are underneath the camera, look to the right for a doorway traced by blue lights with a Retinal Scanner next to it.

Deal with the visible terrorist: either shoot him and the second one who appears, or use the Whistle button to draw the first one into the dark, KO him, then snipe or grab the second guy.

Around the corner, you will find a medkit against the wall.

Pick up the data stick dropped by the second terrorist.

Dump both bodies around the corner underneath the camera where it is dark.

Continue past the medkit to the end of the room, find the pipe, climb up it, and go hand over hand to the left to reach an opening in the ceiling.

Save at the Checkpoint (an auto-save point you restart from on death) halfway down the ceiling vent.

At the opening at the end of the vent, turn left, crouch in the corner on the walkway, and observe the room, noting the terrorists and the spotlight at the far end.

Move very slowly to the right edge of the platform, stand up, and look to the immediate left.

You will see Sadono and his bodyguard. There are 4 other terrorists in the room who cannot shoot you as long as you stay on the catwalk.

Shoot one terrorist with a headshot (a shot that lands on the enemy's head, usually an instant kill), causing the others to step into view around boxes on the ground.

Shoot the remaining terrorists.

When only Sadono is left, shoot out all the lights in the room except the moving spotlights.

Silently drop down to the ground, avoid the spotlight, move behind Sadono, and grab him.

Warning: Sadono only needs to shoot Sam ONE TIME to kill him.

Interrogate Sadono.

Maneuver Sadono to the Retinal Scanner on the right-hand side of the room nearest to where Sam dropped down. The scanner near the power panels cannot be opened by Sadono.

When Sadono is at the right retinal scanner, interact with it to have Sam hold his pistol to Sadono's head while he uses the scanner to open the door.

At the top of a well-lighted ramp, make Sadono open another door with a retinal scanner.

Knock Sadono out.
