Hi everyone.

Im in the library. I can change into the woman but cant move the stuff in the opening. Just wish i can shut the woman in the library up. Lol. Anyway, I dont know how to get pass the library. I killed the ghosts in rooms 1,2,3 etc. Ive opened the valve in room 3. What do I do next. Please help.

Thanks for your time.

Okay, this is what you do. You go through rooms 1-5 in the science block and when you've nabbed all the Poltergeists Astral will get a new power. You then go into the room with the Astral sign and use the new Poltergeist power to shift all the stuff blocking your way. Make your way through all the rooms and finally you'll walk down a ramp, just before you get to an exit door. You'll find a box of Smoke grenades on the floor.
In the Library, use your grenade launcher (press square to switch to smoke) to see the poltergeist running around in there, and lob your capture grenade at it. When it's caught, you'll be able to progress.
