Biohazard 4 (Castle Version)



"Castle" was the second stage of Resident Evil 4's development. In the West it is otherwise known as the "Fog version".

Plot
This version's premise featured Leon infiltrating a European castle belonging to Oswell E. Spencer, and being infected by a new bacteria-sized virus in a quest to eradicate the Progenitor virus. One of the most notable areas shown in this version was a flying airship.

Development
The "Castle" build was first unveiled at the Tokyo Game Show's Spring 2001 expo, with Hiroshi Shibata attached as the Director. The story was written by Flagship writer Noboru Sugimura, and Resident Evil 3: Nemesis writer, Yasuhisa Kawamura.

In November 2002, Resident Evil 4 was announced as one of the "Capcom Five", a Nintendo-exclusivity agreement devised to aid the console manufacturer's failing sales.
