This level is tougher than the Dam, but not that hard. You start off in a vent. Go down the hole that leads into the stall. Side-step to the right and take out the man with your silenced PP7. Pick up his ammo, and open the door next to the the stall you came out of. Shoot the guy with your PP7 and get his ammo. Now, go to the stall on the opposite side of the room. Open the two middel stall doors and shoot the men. Exit the bathroom and walk along the railing until you can look down into the hallway below. Wait for a soldier to stroll by and pick him off with your PP7. More men should come racing up the stairs, so use your PP7 to take them out. Open the double doors behind you, but don't move to the stairs just yet. Look at the base of the stairs, and shoot the man below with your PP7. Go down the stairs, and collect the ammo. Open the two double doors the solder you just killed had his back to. Open it, and turn to the left. A soldier should have his back to you. Aim at the back of his head and ice him with a single shot (or if you're feeling goofy, shoot his butt. Ouch!). Be careful, becomes sometimes a man will come out of the double doors on your right! Pick up the dead man's keycard, and then open the double doors on your right. You should come to a dead end with two doors: one straight ahead, and one on your left. Open the door ahead of you, and you should enter a lab-like room. Turn to your left, and you'll see a door. Open it, and run behind the boxes. Lean out into the hallway and shoot any men out there with your PP7. Next, go down to the large, brown door. Open it, then press back against the wall. Men should rush out, but you should be able to use your PP7 to take care of them. Wait until you have killed 3 men, then enter the room. Walk up to the console, and press B. Then, exit the room and run toward the boxes. Turn left, and open the brown door. Go through the open brown door in the next room before it closes. If it closes, you must go back and activate the console again. Lean out into the room with the lockers and take out the first soldier. Then, walk around and kill the other guy. Switch to you KF7. Four men should come through the console controlled door. Just stand next to the door, and ice each soldier has he comes in. Then, open the brown door in the opppsite side of the room, then quickly run back into the area with the lockers. Wait for 3 more men to come through, then enter the next hallway. Look in the doors on each side of the hallway for Dr. Doak. Dr. Doak is the double agent you need to contact. His placement is random. He'll either be in one of the two rooms adjacent to the hallway, or in one of the laboraties later on in the level. Open the two doors at the end of the hallway. Fire a few shots into the next door, and wait for men to come. There are quite a few of them, but they should be no match for your KF7. Enter the room and go left. Shoot any stragglers, and fire a few bullets into the brown door. Wait until a guy opens it, kill him, then enter the laboratory area. Objective A completed. Men will come running down the stairs as you go up them, so shoot them before they shoot you. Go up the stairs, then you should come to a bunch a labs. Search each one for Dr. Doak if you haven't found him yet, and he'll give you the door decoder. Shoot any men in the area. Then, head down a hallway between two of the labs. Turn left, you should see two men with their backs to you. Kill them, then switch to the door decoder in your inventory. Use it to open the locked brown door. Head down the stairs and meet up with 006, Alec Trevelyan. Talk with him until it says Objective C completed. Then, switch to your remote mines, and place them on the tanks so that they face the tank in front of them. When the alarm goes off, hide behind the tanks. Eventually, the men will stop shooting, and Colonel Arkady Ouromov will be holding Alec at gunpoint. When Alec says "Finish the job, James", blow up the tanks. Ouromov will execute Alec. Turn around, and exit through the double doors behind you. Facility complete.
