Part 19

From the second doorway in the room, kill the enemy with Dual Ingrams, collect his weapons and painkillers for an MP5.

Head right from the corridor's end to a staircase and narrow walkway. Save.

Go up the plank and into the walkway, then retreat and hide behind the large box to the left.

Wait for five cleaners to attack, use shotguns and bullet time (a mechanic allowing you to slow down time) to defeat them. Collect their weapons for MP5 ammo.

Enter the walkway again and go up the stairs on the left. Hide behind the box to the left and kill the cleaner at the corridor's far end.

Proceed forward and down the next staircase to the floor below to find Desert Eagle ammo.

Go back up and ascend another set of stairs to the top floor. Enter the room on the right side of the walkway. Save.

Enter the first room on the opposite side and kill the cleaner outside the second door.

Peek around the first door to find a cleaner behind boxes on the left. Kill him with the MP5.

Shootdodge (a move where you dive while firing) through the second door into the opposite room and kill the cleaner to the left of that room's doorway.

Take cover (press the cover button to crouch behind walls or objects) behind the left side of the room's doorway and wait for three black-suits to approach. Kill them. Collect all their Kalashnikovs.

Take cover in the same room. Equip the Dragunov and snipe the three black-suits at the corridor's far end.

Move forward through the door at the end of the corridor.

Go right and around the glass-wall divider. Go left, then right.

Go through the door and hide behind the boxes on the left. Kill the first of three cleaners with a headshot (a shot to the enemy's head, dealing critical damage), then kill the other two.

Snipe the two additional cleaners arriving at the room's far end with the MP5.

Go to the end of the room. Peek into the room on the right to find a cleaner outside its second door. Kill him and go through that room.

Head right and jump down to the floor below on the right side to end the level.

After a cutscene (a non-interactive cinematic the game plays automatically), exit the room and look back into it. Kill the cleaner who jumps in from the top and collect all ammo.

Exit the room again and go right. Stop near the second room (a broken room with a broken doorway and a plank).

Go to the extreme of the plank and jump onto the metal platform leading to the room on the other side. Check the room for painkillers and return to the metal platform.

Jump from the platform's extreme onto the plank (if it hasn't fallen). If it has, jump onto the broken wall to your right, left from the plank.

Go right again, and through the wooden double-doorway. You will enter a room with a balcony.

Equip the MP5 and go into the room and onto the balcony. Look left and snipe the cleaner on a building roof slightly to your left with the MP5.

Exit the balcony and room. Equip the Kalashnikov or MP5 and head right. Peek around the broken wall on the left to see a black-suit coming through a door. Kill him and collect his weapon and painkillers.

Collect painkillers from the red box and stand against that door. Save.

Equip the Kalashnikov and MP5, and go through the door. Keep running ahead and kill the black-suit in front of you.

Stand under the ramp near the killed black-suit's position. Use bullet time and slowly move backward while looking up. Shoot as soon as you see their heads to kill them one by one. Save.

Go up the ramp and collect all the Kalashnikov and painkillers dropped by the enemies.

Come back down and go to the other side of this room. Go through the door, left, forward, and through another door. A cutscene plays. Save.

Enter bullet time and kill the guy in front of the doorway. Quickly equip the Dragunov and look down to the extreme right of the open yard below.

Snipe the three black-suits running towards Max before they get halfway near. Max will join the fight; protect him and do not let him get killed, or it's 'GAME OVER'.

Go through the new door (where you just killed a black-suit after the cutscene), then another, and kill the black-suit thug here (if you didn't snipe the thug on the roof of another building to your left earlier).
