Echo Night 2: Nemuri no Shihaisha is a first person adventure. Like the first game, Echo Night 2 is played from a first-person perspective, but unlike most other first-person games there is no use of firearms in the game. When confronted by a ghost the player must turn on the lights in the room by means of a light switch. The player is often transported into the past via the passengers or certain objects. Once the player fulfills a task important to a spirit they will vanish and drop an "Astral Piece" which can be used to get a different ending scene.
The story begins when Rebeca Morgan, the girlfriend of the main protagonist (Richard Osmond), disappears mysteriously. During his search, Richard arrives at a library and discovers, inside of a book, the image of woman called Cristina Collins, whom died long ago. The peculiar thing is, despite her old clothes and hair style, the woman is identical to his missing girlfriend. After collecting some clues, he arrives at a beautiful mansion. He will soon discover this mansion is inhabited by spirits. He must help them to find peace and discover the secrets the bewitched mansion hides. Secrets that will help him find out the reason behind disappearance of his girlfriend, which is strangely related.
