* ExecutiveMeddling / WhatCouldHaveBeen: ''Origins'' changed development teams entirely not long before it was released. The original version was a ''VideoGame/ResidentEvil4'' clone that drew on a great deal more material from the movie. The first previews indicated the game was going to use the OverTheShoulder camera to deal with the smaller PSP screen.
* ImproperlyPlacedFirearms/SelectiveHistoricalArmoury: The game is set to be in 1979 but AK-type rifles only entered the States after 1982.
* KonamiCode: Inputting it unlocks [[SilentHill3 Vincent's]] outfit.
* LetsPlay: [[http://lparchive.org/Silent-Hill-Origins/ Voidburger]] does a very informative and hilarious video LP.
