Silent Hill 4: The Room Cheats

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.

Successfully complete the game with a rank of at least 9 big stars. Start a game in "Brand New Fear" mode and look in Room 202 in the Apartment World to find a submachine gun for Eileen.

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.

At the Subway World 2nd Time, in the corridor of B2 floor (after the stairs and the Wallmen), take it over the creatures.
