Professor Layton vs. Phoenix Wright: Ace Attorney

Layton-kyōju VS Gyakuten Saiban (レイトン教授 VS 逆転裁判, lit. "Professor Layton VS Turnabout Trial") a crossover adventure puzzle video game developed by Level-5 and Capcom and published by Capcom for the Nintendo 3DS. The game is a crossover between the Ace Attorney and the Professor Layton adventure series and features scenario designs from Shu Takumi, the series director for the Ace Attorney series, though he was not in charge of the script. The game combines the trademark puzzle and trial themes from each series. The Capcom part of the development team was put in charge of the art.

Plot premise
Hershel Layton, Phoenix Wright, Luke Triton and Maya Fey find themselves in Labyrinth City, a strange medieval-style city in a different world from their own that has recently been falling victim to a number of seemingly impossible occurrences. The town is controlled by an evil villain known as the Story Teller and its shadows conceal witches. When a girl named Mahoney is accused of witchcraft, Wright takes on the challenge, which consists of "Witch Trials", where the familiar procedures of the Ace Attorney games are thrown out, and he must contend with an entire mob of conferring witnesses.

Development
The idea of a crossover between the Professor Layton and Ace Attorney series was a corporate one. Shu Takumi had apparently not known much about the project until well after development had proceeded on it. Though Level-5 president Akihiro Hino was a fan of the Ace Attorney series, Professor Layton producer Jun Suzuki had never even played any of the games before the crossover began development. The development team went through a trial-and-error process to see how best to merge aspects of the two series. While Wright is drawn more simply than in his games, Layton is drawn in more detail.

The transition to 3D models was new to the Ace Attorney series, which previously only used brief instances of 3D imagery in Rise from the Ashes and Apollo Justice: Ace Attorney. While Takumi had stated his preference for 2D graphics in his games in the past, he accepted that the transition to the 3DS made 3D graphics inevitable, and that a 3D environment would add depth, character and flexibility to the game's depictions of the courtroom.

Announcement
The game was officially announced at the Level-5 Vision 2010 press conference on October 19, 2010. The game was first teased as a crossover between Capcom and Level-5 by Keiji Inafune, then head of Capcom's R&D Management Group, who was talking to Japanese business magazine Diamond prior to the Tokyo Game Show 2010. He mentioned that he had great respect for Akihiro Hino. On September 25, 2010, the game was accidentally outed on Twitter when Jiro Ishii of Level-5 accidentally tweeted to Jin Fujisawa of Square Enix, "Huh? Oh, Gyakuten XX. I'm making it, with Mr. Takumi!" in Japanese, which led to rampant speculation of a new Ace Attorney game being developed by Level-5, similarly to how new Capcom games from established franchises are being developed externally. Jiro Ishii quickly covered up this leak, who tweeted later that day, "A misunderstanding seems to be spreading, so let me say that I'm currently working only on Time Travelers." This evidently turned out to be false; Ishii was working on both titles. A Nintendo Dream magazine issue featured the game and Gyakuten Kenji 2.

A year later, the game made a reappearance at the Tokyo Game Show on September 2011, as well as at the October 2011 Level-5 World event and the January 2012 Gyakuten Saiban Anniversary Event, all of which focused on Phoenix Wright's gameplay. It was then revealed that a 2012 release was planned. A year after that, the release date was revealed some time before another showing at Tokyo Game Show 2012. The game was released in Japan on November 29, 2012. An international release date has yet to be announced.

Gameplay
The game features a combination of gameplay elements from both series, featuring the trademark puzzles from the Professor Layton series as well as trials from the Ace Attorney series. Professor Hershel Layton has to solve the mysteries of the strange world while Phoenix Wright participates in "Witch Trials", which are similar to the court trials in the Ace Attorney series, to prove the innocence of his client, who has been accused of witchcraft. The game also features fully-voiced anime style cutscenes that are common in the Professor Layton games but a first for the Ace Attorney series.

Gunshū Saiban
"Shu Takumi"

- When you try to imagine medieval court proceedings, you tend to picture these mob scenes with people shouting out accusations at the tops of their lungs. It's a crazy scene, and since this game's set in a medieval city, I wanted to present a court the likes of which we've never seen before.

Gunshū Saiban ("Mob Judgment") is a gameplay feature in the Witch Trials. At times, Phoenix must "cross-examine" a group of several witnesses, who may freely confer with one another. Witnesses can also jump in or leave the group at any time.
