Blood, Sweat & Tears
Follow Tommy into the sweatshop and through the first few rooms. An enemy will shoot Tommy dead after he kicks down a door. Take cover by the door and shoot the killer in the head when he pops up to fire. Then, enter the room and immediately take cover behind the container in front of the doorway. An enemy will jump through the window at the other end of the room and another will appear in the doorway next to the window. Gun down the enemy who jumps through the window while he's out in the open. Take down the guy by the door as well before moving out from cover.
The enemy that appeared in the doorway will have been wielding a shotgun, so be sure to pick this weapon up before moving on. There are two or three more enemies in the room through the bead curtain. You can flank them by heading through the doorway across from the door you used to enter the room, kicking open the door at the end of the corridor and then taking cover by the double-door at the other end of the room you come to.
When the room is clear, head inside go through the doorway on the right. Move through the next couple of rooms and kick down the door at the end of the corridor you come to. Head up the stairs here and then down the stairs at the other end of the walkway to get past the barricade. Continue through the series of doorways straight ahead and you'll reach another workshop.
Kill five enemies while holding a human shield to unlock the Chinese Waltz achievement/trophy.
Enter the workshop, turn right and head through the doorway there. There's an enemy in the next room you can easily take as a human shield. This is a good spot to unlock the Chinese Waltz Xbox 360 achievement or PlayStation 3 trophy, which requires you to take a human shield and kill five enemies while the shield is alive. There are at least five enemies in the next couple of rooms, so you should be able to pull it off quite easily if you go for headshots.
The enemy is standing with his back turned to the doorway. To take him as a human shield, approach him and press the B/Circle button. While you have a human shield, other enemies will be hesitant to fire. You can still use a pistol, so taking a human shield can definitely be advantageous. Do note that enemies will still shoot at you, especially if you're shooting at them.
Once you've taken the enemy in the doorway as a human shield, take aim and headshot the enemy directly in front of you. There's another enemy further up, but he will most likely retreat up the stairs. If he doesn't, take him down too and then move toward the trash bins in the middle of the room. At least two enemies should be visible in the window in the top-right corner of the room. You'll have to take these guys out with headshots. Your accuracy will improve if you aren't moving, so stand still and take your shot when these enemies pop out from cover.
When the enemies in the window are down, push toward the stairs at the other end of the room. One or two enemies should take cover by the wall at the top of the stairs. Remain at the bottom of the stairs, hug the wall to the left and take down these enemies. One of them is likely wielding a shotgun, so keep your distance. If need be, stand further back and wait for the enemy to pop out from cover to fire rather than trying to get a bead on him while he's covering.
Start up the stairs once you've cleared the enemies at the top. Don't head to the top of the stairs yet; allow Kane to run up and distract the enemies upstairs first. You should have four kills at this point. Once Kane is attracting gunfire from the enemies at the top of the stairs, proceed to the top and nab a fifth kill before executing your human shield and taking cover.
Unlocking the Chinese Waltz achievement/trophy
Clear out the remaining enemies in the room at the top of the stairs and then scan the area for pistol and shotgun ammo (by pressing down on the D-pad). Before kicking down the closed door at the other end of the room, look for a fire extinguisher on the ground to the right of it. Pick up the fire extinguisher, kick down the door, then stand back and throw the fire extinguisher to the end of the corridor. Be careful here, as an enemy armed with an Uzi gun will kick down the door on the right and fire at you. Quickly shoot the fire extinguisher when it reaches the container at the other end of the corridor and you should be able to take him out as well as one or two other enemies.
Ensure the man with the Uzi is down before entering the corridor and moving through the first doorway on your right. There's another enemy armed with a submachine gun through the next door, so be ready with your shotgun as you kick the door down. There are a couple more enemies in the room at the end of the corridor, so take cover by the doorway and eliminate these enemies before entering. Proceed through the open door at the other end of the room to head outside.
Once you've regrouped with Glazer's men, follow them to the courtyard. An enemy will immediately shoot one of Glazer's men in the head. He drops a Vamazast assault rifle; swap your pistol for this weapon, as its accuracy will help you greatly here. Your accuracy is improved while crouching, allowing you to easily gun down the enemies on the second floor and in the courtyard below. The Vamazast does have quite a bit of kickback, so push the Right Stick down while firing to keep your aim steady.
Clear the courtyard and second floor walkway of enemies and then follow your allies through the doorway at the other end of the area. Lift the door here to proceed to the next area, then follow the others up the steps beyond the door and through the door at the end of the walkway. Have your shotgun ready and kick down the door straight across from the door you used to enter the building. As soon as the door is down, point your shotgun at the doorway at the other end of the room and blast the group of enemies that comes through before they can get behind cover. Continue through the doorway once you've dealt with these enemies. Be careful, as there may be one or two more enemies through the bead curtains here.
Use your shotgun to quickly put down the group of enemies as they enter the room.
Move through the bead curtains once you're certain the room is clear and kick down the door to your left. Proceed through the door, head down the stairs and lift the door at the bottom. Enter the warehouse and kick down the door on the platform at the far end of the warehouse to trigger a cutscene.
After the cutscene, sprint through the doorway straight ahead and head up the stairs. At the top of the stairs, turn through the doorway on the wall to your left and look for two Vamazast assault rifles on the table in this room. Pick up both weapons and then take cover by one of the windows in the previous room. Gun down a few of the enemies below and a getaway van will then appear. You must destroy the getaway van to prevent the men from reporting back to Glazer. You don't have a whole lot of time before the van pulls out, so act quickly. The Vamazast will make short work of the van, so just take cover by the window and continuously blindfire (by holding RT/R1 while behind cover without using LT/L1 to aim) at the van. Push the Right Stick down slightly to keep the gun steady while firing.
The white bar in the distance marker pointing to the van indicates how much damage the vehicle has taken. Deplete the meter completely to wreck the van and prevent Glazer's men from escaping.
Destroying the getaway van
Once you've managed to destroy the van, police will appear on the walkway across from the windows. Remain where you are and use your assault rifle to eliminate as many of the police officers on the walkway as you can. When the walkway is clear, kick down the door at the end of the corridor, move through this room and step onto the walkway. Take cover behind one of the stacks boxes along the walkway if need be and blast any cops that appear in the doorway or windows at the other end.
Be sure to pick up the TOQ shotgun used by the police once the way is clear, as this weapon is one of the most effective in the early levels. Keep an eye out for revolvers as well.
When the way is clear, proceed down the steps in the room at the far end of the second floor and lift the door at the bottom of the steps to exit the warehouse. Move through the alley and you will soon encounter a strolling police officer. Blast him with your shotgun and then back up to avoid the police dog on the way. You can kill this dog with auto-aim by simply tilting the Right Stick down and firing without aiming. Once you've dealt with the dog, take cover around the corner and blindfire your shotgun to kill the officers that come after you.
The TOQ Model 18 shotgun is an effective weapon in the early chapters.
Clear the alley and turn left when you can. Climb the wall at the end of this path to complete the chapter.
