The Spirit List is an inventory of all the ghosts you've managed to capture throughout all your games. To unlock it, simply finish the game once on any difficulty level. Save your End Game data, load it and start a new game from the Bonus Features menu. The Spirit List is the same as the Ghost List in Fatal Frame 1. There will be a percentage indicator telling you how complete your list is. The Spirit List appears in your item and photo menu. Completing 100% of the list will unlock other bonus features.
