Fatal Frame II: Crimson Butterfly Director's Cut Unlock Hard Mode
Successfully complete the game under the normal difficulty setting to also unlock the "Hard Mode" options, two alternate costumes (red/blue kimono and dark blue kimono), and glasses for Mio.
Easy Fatal Frame shot:
When fighting a ghost, let it catch Mayu. The ghost will grab Mayu and you will have a chance to take a Fatal Frame shot.
Fight Twins Spirit:
When one of them raises her hand after the red circle fast, do not attack her or you will be attacked by her sister behind you, If she raised her hand after the red circle slowly, this is the real spirit and you will not lose film on the twin's doll, if you know which is the real one.
Notice that the Twin's spirit has red lips and the doll does not. This will make it easier to learn which is the real one.
Screen saver:
Keep the game unpaused, and out of the menu/map screen. Allow Mio to remain idle for exactly five minutes. A ghostly image of a woman's face will fade onto a random point on the screen (looking at you) for a moment before disappearing. Then, the screen will get blurry for a moment and the woman's face will fade back in on another location on the screen. This will keep repeating until you use the controller again.
