​Plot
The player assumes the role of a rookie FBI agent who is knocked out during an undercover investigation. The player wakes up in a strange hotel and tries to escape despite the various traps laid out throughout the building. The genius detective L provides help in the escape via a fictional in-game PDA, and the player feeds L information that is gathered throughout the hotel and outside. The software also includes a separate "L Communicator" mode in which users can make friends with L by giving him sweets. If the user succeeds in making friends with L, L will "talk" with the user via voice.
