I have read all the messages on the library. I still do not see the poltergiest. I use square, grenade, goggles and still I do not SEE THE POLTERGEIST. I have hit him invisible a few times but NEVER HAVE SEEN HIM. Am I missing something, some step. I you can PLEASE HELP A FELLOW GIRL GAME PLAYER. I need precise direction on what to do. THANK YOU XUANATIA!!!

Okay, just to check...you've got the smoke grenades, right?
Strange, one of my YouTube friends is having exactly the same problem, in the same place. Unfortunately there's no way to skip this part, so the only answer we could come up with was for me to upload the save file for the next checkpoint for him to download. Haven't tried it yet, though.

There are cheats you can use for infinite health, and to make the little bugger weaker if he's being a real pain, but if you've got a glitch, I don't know any way around it.
