I’d say that this game has been unmasked, but then that would be a pun best left masked.
Professor Layton is coming back for more, and after a successful trilogy, he’ll back for another trilogy that starts with Professor Layton and the Miracle Mask (or Mask of Miracles, as Wikipedia would have it). We don’t have any details other than the name, but all that will be revealed in the latest issue of Famitsu.
What we do know about the game is that it will feature a complete overhaul of the game system, and that the Mask of Miracles will be related to the bad guy of Devil’s Flute, Death Call. It’s all a mystery!
