Chapter Five: A Sign of Her Passage
Walk forward to the door. There are several cleaners in the stairwell. You can wait for them to emerge or attack them behind the door. Watch out for grenades! You can head up the stairs. Although it's a dead-end, there's a stack of boxes at the top that contains some ammo and painkillers. Knock over the boxes to retrieve the items. Descend the stairs.
You'll hear someone shouting that they're stuck. It's the hobo again. Move the board to rescue him and he'll help you out. Continue down the stairs. At the bottom, go right to the door marked "Exit". Talk to the woman behind the door. She suggests getting out via a window on the third floor.
Walk to the end of the hall and kill the three cleaners. Go down the stairs on the left. You'll enter the utility room. Turn the valve to shut off the gas. Search the nearby lockers for ammo and painkillers. Return up the stairs. Enemies are in the hall to the right so activate bullet time before exiting.
Return up the stairs to the floor marked "A3". It's where you found the hobo. The flames at the end of the hall are no longer there. Walk there and enter the doorway on the left. Search the bathroom for two bottles of painkillers. Approach the open window on the left and hop out to the ledge. Your two allies stay behind.
Scurry along the ledge to the left fast. Enemies emerge in the courtyard below. Your allies will shoot at them and, if you're lucky, finish them off. Hurry to the scaffolding on the left. You can stand here and eliminate remaining guards with a long-range weapon like a desert eagle or sniper rifle. Go up to the upper ledge and turn to the left to see another ledge you can jump to. Jump over there then hop down onto the next scaffolding.
Hop to the left and it starts to fall. As it does, hop off to the right onto another part of the scaffolding. It will begin to fall also. Now drop off to the left onto the solid piece of scaffolding. It will fall to the ground.
When it falls, a van backs into the courtyard and deposits several guards. Scurry around a corner and, if your allies are alive, these guards will start shooting at them. Activate bullet time and charge out into the courtyard and start blasting. Remain in bullet time for each kill and you'll begin to move even faster. Kill all guards and the chapter ends. You could also toss a grenade at the van doors and kill some or all of them. Then just mop up any survivors to complete the chapter.
