This level doesn't look as familiar as the surface did. You start out in a cell, with nothing but your watch magnet. Use the magnet to get your cell key. When the guard walks by your cell, open the door and chop him to death. Then, open up Natalya's cell and let her out. With the KF7 in hand, stand by the door and look out the glass. Men will come walking by. A one nicely placed shot will take care of them. After 4 men have walked by, walk out into the hallway. Turn left and head for the stairs. There should be a man walking. Shoot him, the quickly run up the stairs. Enter the next room, and kill the guys in there. Pick out the document on the table. Now, a few billion guys should come running in, so wait by the side of the door. Make sure to keep Natalya out of the way. Once guys pretty much stop coming, you should have a keycard. Use the keycard to open the double doors all the men came through. Aim down the hallway and blast the surveillance camera. Kill any stragglers, and enter the room on your right. Aim up and blow up the surveillance camera. Now, go through the brown door on your left. This is the area where you begin your first mission at the bunker. Don't go through the door just yet! At the entrance, aim up. You'll see a camera swinging back and forth. Blast it. Open the door in front of you, and take out the man with one shot. Pick up the CCTV tape on the table. Now, exit this area back the way you came. There should be two sets of double doors on your right. Stand in front of the last set, and shoot the guy inside, as well as the camera hanging on the left wall. Enter the room, and get the man's gun and key. Now, go back down to the jail area. Stand in front of the door leading to the cells. This time, go forward. There should be a door at your left. Aim through the glass, and shoot the guy at the computer. Two more guys should come, so blast them. Go to the computer, and pick up a key. Open the safe in the corner, and pick up two PP7s, and the Goldeneye operations manual. Now, exit the room, and go through the window-less set of double doors. Watch out for guys coming from the door far down the hallway. There should be another hallway on your left. Quickly lean out, fire a few rounds, then lean back. Wait for two guys to come. Kill them, then aim down the hallway at a camera. Blast it, then head towards the doors in the distance. You probably don't have the right keycard to open these doors, so fire a couple rounds through the windows to attract attention. Men will pour out. One will be carrying a clipboard. Pick it up to complete your second objective. Now, enter the room. There are four little "slots" in the room where the men come. Eliminate the men in each slot. Then, go out the opposite entrance, and up the stairs on the right. Switch to your PP7's. Walk out just far enough so you can see the two guys on top of the little staircase. Now, shoot the all the guys near the left wall. Next, shoot all the guys on the little platform on your right. Natalya will now run up to check the console. Watch where she runs, the last camera is in that little room, against the left wall. Blow it up and then go through the glass doors and exit the same way you did in the first bunker. Now, why did Ouromov set off the Goldeneye on Severnaya.....?
