Silent Hill 4: The Room Cheats

Hint: Creepy Call
Whenever you walk around in Henry's apartment, go to his bedroom and look out of his window. If you notice, you will see a billboard that says "Bar Ashfield" on it and right below it as a phone number. Then go to his phone next to his bed and dial: 555 – 3750. It will play a little creepy call makes Henry feel disturbed.

Hint: Moving Loading Screens
Whenever you enter a new room and get the loading screens with the weird symbols, move the left analog stick around and watch as they move across the screen.

Hint: Possessions
Throughout the latter part of the game, your apartment will become possessed and/or haunted. If you took the Shabby Doll that the mysterious man gave you inside of the Apartment World, Ghosts will slowly come into your apartment. No matter what, however, your apartment will become possessed from time to time. You must eliminate these possessions by lighting Holy Candles near the possessed item, or equipping a Saint Medallion once you go near it.

After finishing the game one time save and reload
your save.  Then go to the Forrest World and look for the cut tree.

To get different types of endings, you must do one of four things. Either clear your apartment of ghosts before the final battle, or do not; and let Eileen die or not. These two course of actions create four different endings.

Ok this is what you do when you are in your building go the any window and look out it
look at the Billboard and write down the number on it
then go to your phone next to Harry's bed

Click on the phone to pick it up then ring the number on the Billboard.

Then listen as the bar is not what is seems !?!?!

Start a game in "Brand New Fear" mode. Continue until the "Outside of Room 302" part of the game. Enter Room 303 and search it for Eileen's nurse costume. Collect it and complete the game. When you start a new game, you can now have Eileen dressed as a nurse.
