Japanese mobile giant DeNA announced that Level-5's Professor Layton series, once exclusive to Nintendo's portable consoles, will soon see a new entry for DeNA's Mobage social games portal.

Professor Layton Royale, a crossover title featuring characters from Mobage's Kaito Royale series, will be released this Fall in Japan. No word yet on whether an overseas release is in the works.

Layton himself is no stranger to crossovers, having already announced a partnership with Capcom's Phoenix Wright and friends in the upcoming 3DS game Layton Kyouju vs Gyakuten Saiban. DeNA's game, however, marks a rare venture on a non-Nintendo platform (Layton's second, following a previous Mobage release -- thanks Joe) and is the franchise's first social game.

Little else is known about the game at this point, save for the fact that players will be able to assume the role of either a thief, a detective, or -- for the less ambitious players, I guess -- a "citizen" in Layton's world.
