Origins was originally being made by Climax LA but was fortunately scrapped (It originally featured Zombies) and production was transferred to Climax UK. With Origins now in the UK teams hands they had to pretty much start from scratch to create a game worthy of the Silent Hill title.
Below is the prototype video in which there are a number of changes and difference within it that would ultimately lead up to the final finished product.
You can also see an additional video below which features the original early work and ideas for Origins when it was still being made by Climax LA.
