After the elevator takes you down, go straight on until you walk into a large room that doesn't look like anything you've seen here before. There is a document by the guard's desk.

As soon as you turn another corner, the alarm will go off and you'll see the ghost again. Turn around and run because this time he'll strike. A short while later you'll be watching a nice cutscene in which the pursuer leaves you alone.

Keep going in the same direction a little longer, and a door will open on the left. Behind the glass window, you will see a fairly normal man sitting in a wheelchair. He'll ask you to kill Billy in the laboratory, because he's the ghost.

Having nothing better to do, agree. When you leave the room, turn left and you'll see another door opening for you. Go through it and run down the corridor, then turn left at the end. The arrow on the wall will point you in the right direction.

At the end of the corridor, behind the double doors, turn right and then go past the generators to reach the stairs. Go up and run to the open door, then through the decontamination chamber. Watch out for Billy breathing down your neck.

There are only two paths from here, both having you switching things on. First, go right. This is not the time for sneaking anymore; it's time for sprinting only.

Turn left and start climbing the stairs, and when you're up, get to the other side. Turn on the camera and go right, then follow the path until you reach the decontamination chamber. Billy will stop chasing you for a while.

Run up another set of stairs to find a box from which you need to rip cables (shining in green). Do what must be done and go back to middle room. Now you can take the guy on.
