Trivia
Silent Hill 4 wasn't originally going to be a Silent Hill game. Towards the end of production, though, Konami decided to make it into the Silent Hill series. That's the reason why Silent Hill 4 doesn't actually take place in Silent Hill.
Silent hill 4 is the very first Silent hill game to be rated 18.
If you turn on the radio in the first half of the game, when it still gives you the news, the game's producer, Suguru Murakoshi, is said to have been caught "urinating from atop a utility pole".
Another reference to Silent Hill 2, after you complete Building World, go into the bathroom and select the toilet. It will ask you if you want to remove an item that is stuck. The response is quite amusing and is a reference to James Sunderland removing a wallet from a toilet in Silent Hill 2. This was also referenced in Silent Hill 3 with Heather in the bathroom of the alternate mall.
Walter Sullivan is mentioned in Silent Hill 2. He is described as a psychopathic killer who chopped two children into pieces with an axe.
