Professor Layton vs. Phoenix Wright: Ace Attorney will release in Europe on March 28, 2013, Nintendo has announced.
The 3DS title combines the worlds and gameplay of the two franchises, and sees Layton and Wright teaming up to help a young girl named Espella.
Split into two gameplay styles, players will be asked to solve puzzles and question witnesses throughout the game, which Nintendo says brings "the best of both series into one title".
Professor Layton vs. Phoenix Wright: Ace Attorney launched in Japan late last month, and is also due to release in North America in early 2014.
