You should see the reporter again. He will give you the passcode to Strahov and some weapons. A cut scene will occur and Reporter will take you to Strahov. One of the large metal crates is open. It has a med pack. Walk to the large warehouse doors. You will see a cut scene of a large magnet dropping down and moving the metal crate. Get on the large metal crate that is closest to the metal warehouse door and to its left (if you are facing it). Then jump across to the stack of two metal bins. Jump from the stacked metal bins to the airconditioning unit. Turn and face the lowered wall.
Lara will say that she doesn’t want to draw attention to herself. Jump to the bypass that runs perpendicular to the wall that you are on. Do a military crawl across the bridge. At the end of the bridge is a ladder. Take the ladder and go the end of the hall. Open the door and use your security pass. Yu should be above the trucks. There is a bad guy. Kill him and get a pick up. There is another guard around the metal bridge. Kill again for ammo.
Go up the ladder the closest to the door that you entered. At the top of the ladder is a guard. Wait for him to turn around and then climb up, sneak up behind him and knock him out. Pick up his machine gun and move the lever. Go back down and then straight to the end and up a ladder. Follow the metal bridge down to the little room that has the flashing light. You will see a cut scene wherein the metal magnet takes out hanging machine guns. Return to where you first came in. To the right of the door (if you are facing the door) and there is a ladder that will take you to the floor of the warehouse. Go through the small green door at the end of the room.
You enter the basement of the Strahov Fortress. In an area to the right is a metal fence and a dog just beyond the fence. There is a stack of boxes to the left side of the fence. Lara says “I can climb that” and a cut scene shows a small pipe.
You need to push a box in front of the pile, next to the fence. Climb onto the box and push the box closest to the fence over so that it is right next to fence. Climb up again and pull the highest box toward you as close to the fence as you can get. Climb up and drop down on the edge of the box that has just been revealed. Push the third box toward the fence. You will gain a strength upgrade. Get down from the boxes. Across the room to the right you should see a stack of two boxes. You need to push and pull these boxes to the vent which is closest to your set of puzzle boxes. Climb on top of the vent and find a valve. Turn the valve. Get down and go back to the puzzle boxes. Climb on top. Catch the pipe and tuck your legs. Shimmy across and drop down. Beware of the dogs.
There is a ladder to the left. Climb up and pull the levers. It will start stone cutting machines and one will cut a vent shaft. Return to the main floor. Jump on top of the stone slab. Lara says “That’s not any script that I know.” Go back up to the platform with controls. Look up and see a long flat vent that runs the length of the room. Jump up and climb on top of it. Go down to wear the stone cutting machine cut the vent. Jump on top of the cut vent, move to the end. Hang off the edge and drop down again. Catch the bottom of the vent and pull up. Crawl to the end of the vent as far as you can go and drop down.
A cut scene will appear showing Eckhardt killing the reporter. As Eckhardt places his specially gloved hand over the reporter, a bloody symbol is drawn on the wall.
Go to the edge of the vent above the room and drop down after the security guard disappears. You will need to kill the security guard to pick up his passcode. At the end of the hall right before the lasers is a small shelving unit. There is a gun there. You need to go back to the room where you first killed the security guard. There is a small room. You can sneak in and break the guy’s neck. He has ammo. The white cabinets have ammo. The next room has two guys. You can avoid these guys. Go to the computer.
There is a cut scene of Lara noticing the BioDome and the fact that her path runs through it. She turns off the power and says that she has to move fast before grid comes back on. There is another cut scene that shows the Bio Dome and some modified beastie that gets out of its cage and kills people.
