Professor Layton developer Level-5 is teaming up with social gaming's DeNA on Professor Layton Royale. Andriasang reports the new social game has players selecting from three different classes and is a crossover of Layton and Kaito Royale.

The game will initially launch in Japan, with the potential of "localized versions to international users on the highly anticipated global Mobage service." With DeNA's acquisition of ngmoco last year -- and Layton's international appeal -- the company would be leaving money on the table if it didn't take advantage of the global opportunity.

Crossovers are something Professor Layton is getting comfortable with, as the puzzle master also has an upcoming collaboration with Capcom's ace attorney in Professor Layton vs. Phoenix Wright for 3DS.
