Nintendo created a huge internet mystery last week. With one little video, the company solved it for everyone and brought an old franchise back to life.

Last week, the gaming giant released a creepy and cryptic teaser for what appeared to be a new horror game. With only the #WhoIsEmio as the description, gamers were left wondering why the company known for making family-friendly games would suddenly make a horror title with such a disturbing teaser trailer. Was this a new IP that Nintendo was creating? Could this be for the rumored Nintendo Switch 2? Could it be an M-rated game? Now, Nintendo has put all that speculation to rest by confirming that the Emio tease is actually for the next entry in the Famicom Detective Club series.

Along with the confirmation of the official title, Emio – The Smiling Man: Famicom Detective Club, Nintendo also released a video featuring series producer Yoshio Sakamoto, known for producing several games in the Metroid series. In the video, Sakamoto talked about the history of Famicom Detective Club, which released two games for the Famicom Disk System in the late 1980s, and how this will be the first new game in over 30 years. He also went into detail about the Smiling Man urban legend created for the game, in which crying girls are presented with a smiling paper bag before being murdered, which is the central mystery that the main characters must solve.
