Since you left the Derelict Apartment intact, you need to cross the rooftops and make your way to Carvier.

Turn right, jump on the metal ledge and climb up the ladder. Jump up to grab the zip line, as Lara explains, and press forward to swing across. Halfway, a helicopter appears and drops its lights to Lara. It will be above at many parts of this level and you need to avoid it as much as you can. If you are careful, Lara will not get damaged a lot, so there is no reason to be in a hurry. Press the Duck button, when Lara says so, to tag her legs up in order to pass the railings from below. Having the Duck button compressed, keep pressing the forward key until you reach the rooftop. Release, run behind the crates and pick up the Health Bandages.

There is a ladder on your left that you can walk down. Carefully reach the edge of the roof and take a standing jump to grab the opposite ledge. Pull up and crawl into the crate to get the Health Bandages. Now you can do either:

• Drop to the walkway you jumped over before: Hang from the edge of the roof and release to grab the sill below. Drop to the walkway and open the door. Pick up the Antique Doubloons, follow the hallway and open the next door at the end.

• Break the skylight: Slide down the roof backwards at the other side (behind the crate - see here). Press Action whilst breaking the skylight to grab the edge of the opening. Release to drop to the floor.

Get the Chocolate Bar from the furniture and pick up the M-V9 Clips from the floor. By breaking the skylight though, you cannot open the door on the right side of the Clips. It opens from the other side, so you missed the Antique Doubloons. Exit the room opening the opposite door.

Cross the walkway. The door at the end leads to a room, but you do not have to go there now. If you want, you can open it and take a look inside. For now, grab the ladder on the left hand side of the door and climb to the top. Then climb up the next short ladder. Pick up the V-Packer Cartridges and do not slide down the roof at the opposite side, because you will reach the end of the level and miss several pick-ups. Instead, make your way back, climb down the short ladder and then the long one. When you reach the bottom, release by pressing Action to land to the ground, next to a flaming barrel.

On the ground - Pull the movable box from the left to get an upgrade in leg strength. Make sure you position the box beneath the ladder, because this is the spot where Lara gets the upgrade. Having the ladder on your right, move forwards and turn left around the corner. Cross the narrow passage to the left of the fence to get a Large Health Pack.

The fence door will not open, but if you take a look on the left part of the fence, you will see that there are no wires (as shown in this screenshot). Jump up to grab this part and press forward to vault over the fence. As soon as you land on the ground, a dog appears that you have to kill (kick\ punch). Collect the K2 Impactor Battery from the dump box, vault over the fence and make your way back to the flaming barrel.

Continue to the other side of the alley and pick up the M-V9 Clips just on the corner. You can climb the fence next to the garage door (jump up and grab), but there is nothing more than a dog. If you are interested in all kills, you have to kill it by kicking\ punching it. Then vault over the fence to return back.

Garage/ Warehouse - Crawl under the partly opened garage door and pick up the Large Health Pack from the left. Climb on the crate opposite the entrance, turn left and jump to grab the walkway ahead. If you jump and grab the upper ledge or climb up the pipe on the left hand side, you will see the door you opened, before climbing down the ladder which led you to this area. There is no reason to go there now, so keep going.

Lara reckons she will make it across if you have got the upgrade in leg strength. If not, you have to go outside, by crawling under the garage door, turn right around the corner and pull\ push the movable box beneath the ladder. Take a running jump to grab the ledge, shimmy left and pull up. Climb up the ladder and pick up the V-Packer Cartridges. Jump the gap and exit by opening the next two doors. Jump across to the fire escape and go down the stairs to get some Antique Doubloons. Go up to the top of the stairs and open the door. Climb up the ladder and open the next door.

Back on the rooftops - You are again at the top of the roofs. Get the Antique Doubloons from the back of the shed and approach the broken fence where the light of the helicopter is. Take a running jump to grab the edge of the opposite roof and pull up. Make sure you jump just before the step of the current roof or Lara will not make it (as shown here). Climb down the ladder and pick up the Health Pills. Climb back up the ladder and jump to the previous roof. Approach the broken fence at the other side of the roof to end the level.

The cut scene shows Lara walking to the edge of the roof. The helicopter finally tracks her and Lara jumps and grabs a pipe. It breaks and she falls down. Our girl is very strong, since she survived from the drop. She now goes to meet Werner Von Croy's friend; Margot Carvier.
