Professor Layton has figured out the secrets of time travel! Though his new game, Professor Layton and the Unwound Future, was originally set to be released in North America on September 20, the clever adventurer has figured out a way to move the release date back in time one week, to September 12.

Unwound Future begins with Professor Layton receiving a letter from his apprentice, Luke -- from ten years in the future. Layton and Luke must travel to the London of the future for urgent puzzle-related business. Apparently, sending someone through time is easier than some of the puzzles.
