Silent Hill Origins started life with an over-the-shoulder, Resident Evil 4 style camera. This version, by Climax LA, lived on until around October 2006, before Climax's UK studios retooled the game. Tons of concept art, gameplay footage, music, and more in my newest video.
I saw you post this on the SH sub-reddit, lol. Nice video though, I love stuff like this. I think the game we ended up getting was better than what this would've turned out to be, but nevertheless this does explain a lot of the weirdness in terms of game design in the final game. Like certain areas in the final game seemed to exist for no reason. This puts it in perspective.
I've always wondered why there was that cloaked person walking in the middle of the road during the intro, now I assume it was originally going to be this Mr. Twilight character. I kinda like that idea, as well as some of the others, but I felt like they took them in misguided directions. Travis as the Pyramid Head might have been interesting if it weren't for its already established history.
