Additional information: This time you will be taking part in a lot of difficult jumps. Thankfully, you won't have to worry about any puzzles. There's only a few of them here and they're very easy to accomplish. Usually you will have to use the grapple in order to pass through to the next section. I have to warn you, though. There's a first boss fight at the end of this level. Your opponent won't be too hard to kill, however you should be ready for that fight. I would recommend that you leave some of the medkits and the ammunition for the machine gun.
A short cut-scene will appear on your screen. You will have an opportunity to take a closer look at Lara's... dress (#1). ;-) The first part of the mission is very simple. You won't have to do any jumps. Start moving towards the stairs. Use them to get to the lower floor. Head on to the bar. Talk to the bartender (press the E key) in order to acquire necessary information (#2).
You must turn around. Start moving towards a small corridor (#1). There's a single door here. Get close to it and press the E button. Lara will come across Nishimura in the new room. It would be wise to listen to this conversation closely. After that, try returning to the main hall. Takamoto will be waiting for you here (#2). After a short conversation, you will have to deal with his bodyguards. Get ready! You will regain a full control over Lara's movements in just a moment!
Start shooting at Takamoto's bodyguards (#1). Bear in mind that you were starting this level without any heavier guns. As a result, I'd strongly recommend taking a machine gun from one of the killed thugs. Thankfully, most of the opponents will be equipped with these weapons. After the fight, a new cut-scene will appear on the screen. Lara will receive a keycard from Nishimura. Start moving towards previously unexplored corridor (#2). It's located near the bar.
Get closer to the elevator. Press the E key in order to use the magnetic card (#1). You received it from Nishimura a little while ago. Enter the elevator. It will take you to the penthouse level. You may exit the elevator. You've probably noticed a bike in one of the surrounding rooms. You'll use it in a few minutes. Turn left and start moving forward (#2).
Enter the roof area. I would recommend that you use your guns now. You don't have to kill anyone. Instead, aim at the huge construction located on your right (#1). Thanks to that, it will blow up. Use the pipe in order to get to the upper platform. You will have to make a small jump to get to it (#2). Make a second jump in order to reach the main roof. Start moving towards the windows.
Get closer to the windowed part of the roof. As you've probably suspected, you will have to get inside the building. In order to do that, you will have to use the grapple. Start pulling the window towards Lara's current position (#1). After that, enter the building. Use the stairs to get to the lower floor. You can now use the bike (the same one I've mentioned before). You will have to press the E key (#2).
Sadly, you won't be able to use the bike for a longer period of time (#1). Once you've left the small room, turn right and head on to the roof area. Make a second right turn. You should be able to see a bridge. Start accelerating. A new cut-scene will appear on your screen in just a few seconds. Once again you will have to press certain movement keys in order to keep Lara alive (#2). Thankfully, it's not that hard to accomplish.
Once you've regained a full control over Lara's movements, start making new jumps. The first one will require you to use one of the nearby metal poles. After that, you should be able to reach a wooden construction (#1). Keep moving forward. Make a single jump. A few difficult moves await you. Before you move on any further, ready your guns and enter the Accurate Aim mode by pressing the Z key. Aim at the highlighted object (#2). Thanks to that, you will be able to proceed to the next section of the wooden construction.
Go ahead and make a jump towards a small rope. From here, you should be able to reach a new platform. You will find yourself at the end of this construction. Make a small jump. Lara will use a new rope and start sliding down towards the next building (#1). Get ready. There are some challenging moves ahead of you. Use the grapple and pull the rope towards Lara in order to get the metal platform swinging.
