 Certain locations in the game are replicated from their appearances  in the previous games in the series, Rei Zero (2001) (VG) (Fatal  Frame) and Rei: Akai Chou (2003) (VG) (Fatal Frame II: Crimson  Butterfly). A prime example is during Hour IV, when Miku explores  areas of the mansion from the original Fatal Frame. She finds a  Camera Obscura in the same spot she found one in the original game,  as well as a stone marker puzzle identical in placement and solution  to the first game a couple of rooms further in.
