Silent Hill 4: The Room
Silent Hill 4: The Room wasn't originally going to be a main Silent Hill game, but a spin-off with different mechanics. Towards the end of production, though, Konami decided to make it a main entry into the Silent Hill series. That's the reason why it doesn't actually take place in Silent Hill.
Silent Hill 4: The Room is the very first Silent Hill game to be rated 18.
- Walter Sullivan is mentioned in Silent Hill 2. He is described as a psychopathic killer who chopped two children into pieces with an axe.
- 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.
- 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".
