From the article, "In Fatal Frame 2: Crimson Butterfly, you play a 12 year old girl stuck in a ghost village. Your only weapon is the Camera Obscura, an antique photography camera that takes pictures of ghosts. You’d think the ghosts themselves would be the enemies, and in a way, they are. But the village has a number of ghosts that appear for the purposes of storytelling as opposed to the purpose of attacking you.
This means that you can never be certain which ghost is a danger, and which ghost isn’t."
