Professor Layton and the Last Specter

Last Specter is the fourth game in the Professor Layton series. It is a prequel that takes place three years before the first trilogy and tells how Professor Layton meets his apprentice Luke Triton. The game contains over 170 puzzles. Professor Layton and the Last Specter also includes an additional role-playing game titled Professor Layton's London Life, which is available from the beginning of the game. London Life, in which players interact with various characters from the series in a city called "Little London," was advertised as having over 100 hours of content. London Life was removed from European versions of the game to prevent the game's release from being significantly delayed due to translation.
