0b - CHAPEL: Carried over into the retail product, is the Chapel as a separate building location, housing the same chandelier (used by Leon to jump across to access the Salazar insignia light puzzle), and is also inspiration for similar interior design within Salazar’s Castle. This area was first seen all the way back in 2001, with the background movie test video #1, of a Chapel engulfed in fire.
0c - WATERWHEEL: The background silhouette of the airship clearly suggests that this is the docking bay, presumably leading to the entrance to Spencer's island protected castle.
0d - UNDER PASSAGE: Connecting main gameplay arena offered by the Castle, to a previous docking/landing area, Leon infiltrates Spencer’s castle from a clandestine underground passageway, with assets used for this area finding their way into the retail incarnation, Salazar’s castle.
