The Great Ace Attorney: Adventures (大逆転裁判 -成歩堂龍ノ介の冒險-; lit. "Great Turnabout Trial: The Adventures of Ryūnosuke Naruhodō") is the ninth entry in the Ace Attorney series of text adventure video games, originally released on the Nintendo 3DS in 2015. It is the first half of The Great Ace Attorney Chronicles for Nintendo Switch, PlayStation 4, and Steam. The game is published by Capcom, directed by Shu Takumi, and produced by Shintaro Kojima. Ace Attorney veteran Kazuya Nuri returns for official art, and the soundtrack is composed by Yasumasa Kitagawa (of Professor Layton vs. Phoenix Wright: Ace Attorney) and Hiromitsu Maeba. Initially released on the Nintendo 3DS in Japan in 2015, it was ported to mobile phones in 2017.



Clockwise from top: Barok van Zieks, Kazuma Asogi, Ryunosuke Naruhodo, Susato Mikotoba, Iris Wilson, and Herlock Sholmes.

  • John Wilson - The victim. An English professor from London who has taught at Imperial Yumei University for the past three years. Based on Dr. John Watson of Sherlock Holmes fame.
  • A judge (Japan).
  • Taketsuchi Auchi (亜内武土) - The prosecutor in this case and the ancestor of Takefumi (Winston Payne) and Fumitake (Gaspen Payne) Auchi. Equally as arrogant and self-confident as his descendants.

Other characters:


The game incorporates the basic investigation/trial formula used in previous Ace Attorney titles, with some changes especially to the trial portions. Unlike previous games, some text graphics in Japanese versions of The Great Ace Attorney Chronicles use English translations alongside or in place of some of the Japanese terms, such as "cross-examination" and episode titles.

Like the previous 3DS titles, Professor Layton vs. Phoenix Wright: Ace Attorney and Phoenix Wright: Ace Attorney - Dual Destinies, the game features 3D character models and backgrounds. However, it also expands on the camera work and animations, treating these aspects with special care[1] to help depict Herlock Sholmes's legendary ability to infer details from even the subtlest of movements.[2] For this purpose, actors from the Himawari Theatre Group were brought in for motion capture.[3]


Ryunosuke Naruhodo
Hold it, Mr. Sholmes!

The Great Ace Attorney Chronicles introduces a new element to investigations, known as "Dance of Deduction" (共同推理 kyōdō suiri, lit. "joint reasoning"). This feature involves Herlock Sholmes using his rapid-fire reasoning to come to a conclusion based on various details that he notices. Naruhodo then has a chance to rebut this train of logic by pointing out flaws and contradictions. One way of doing so is to inspect an individual from various angles to find hidden clues that have escaped Sholmes's notice, possibly leading to an entirely different conclusion. Investigations in The Great Ace Attorney Chronicles also allow for more in-depth background exploration. Additionally, Dances of Deduction feature heavy usage of spotlights and flashy poses, in a fashion reminiscent of Ghost Trick: Phantom Detective.[2]


The trial system has undergone an overhaul, with many elements similar to the witch trials from Professor Layton vs. Phoenix Wright: Ace Attorney. This includes the five-strike penalty system from Phoenix Wright: Ace Attorney and cross-examining multiple witnesses at once. Also like Professor Layton vs. Phoenix Wright: Ace Attorney, pressing a witness results in a dialogue that can be interrupted if the player catches one witness thinking. When pressing a witness, Ryunosuke Naruhodo initially says "Yes!" instead of "Hold it!", but after the first case he will say "Hold it!"

The English courts use a jury system involving six jurors and a judge. The jurors vote by launching flaming knives in a firework-like manner onto a set of scales, one side representing a guilty vote and the other representing a not guilty vote. The jurors can change their votes as the trial progresses. If all six jurors vote "guilty", the defense has the right to a "Summation Examination" to try to convince them to overturn their guilty votes. This works much like cross-examinations, with each juror having their own ideas about the case at hand. Like Professor Layton vs. Phoenix Wright: Ace Attorney, the defense can point out a contradiction between two jurors' statements, though in this game there is a button dedicated to this feature, allowing the player to choose any two statements instead of having one already picked out by the game. If a majority of jurors reverse their decision, the Summation Examination ends in the defense's favor.

The court record appears similar to the one used in Dual Destinies, with five evidence icons fully visible at a time, though two other evidence slots are visible, partially obscured by the arrow buttons used to scroll through the evidence.

Development began a few months after the November 2012 Japanese release of Professor Layton vs. Phoenix Wright: Ace Attorney, when Takumi was asked to start work on a new Ace Attorney game.[4] Because the series had become so long, spanning eight text adventure titles up to that point, a more accessible game was desired. Takumi initially looked to civil trials as a concept, but realizing that it would not lead to very clear-cut conclusions, he instead developed the "Dance of Deduction" concept with Herlock Sholmes, which he had kept in his mind ever since the development of the original Phoenix Wright: Ace Attorney Trilogy.[2] The idea was somewhat vague at first, with Takumi only writing in concept plans, "Holmes says something strange, and you correct that." The concept was later made into a demo in December 2013 and presented to higher-ups at Capcom, signaling a more concrete notion of how these interactions would unfold.[3] Takumi did not actually expect Capcom to accept the proposal.[5][6] The Meiji Japan setting was Nuri's idea, as Takumi originally conceived of the game taking place entirely in London.[3]

The development cycle of the game was long and difficult due to all of the new approaches to the plot and game mechanics. The plot in particular took more effort than Takumi had anticipated. The last Ace Attorney scenario that he had written in an ordinary setting was the 2007 Apollo Justice: Ace Attorney, and he wanted to make a series that could compete with the original trilogy in terms of quality.[2] The game script was huge and changed drastically multiple times before being finalized in April 2015.[7] This in turn provided a daunting challenge for Nuri and the other asset developers. It was as if no one really knew what the final product would look like.[3]

Nuri designed the graphics to have an illustration-like touch to them and convey the feel of the material of the clothing and other objects of the period. The characters were designed to have a more realistic feel with their expressions and movements, though witnesses and jurors were still more comic-looking to make them more recognizable when sitting next to each other. Nuri had difficulty with designing characters due to the limited selection of clothing and hairstyles available for the period, as well as the need to design so many jurors. He had to bring out their personalities in different ways.[8]

Unlike past games, The Great Ace Attorney Chronicles makes extensive use of camera movements. For the asset designers, this meant that they could no longer get away with skimping on details on characters and settings that would not have been very visible in past games. Keeping the hand-drawn feel of the backgrounds even with camera zooming and movement required putting much more detail into the assets. Despite this, the asset designers pulled through and the assets were finished by the end of 2014.[3]


Jump Festa 2014 featured a playable demo of the game.

Demos of the first and second episodes were shown on Capcom TV by producer Kojima.

On June 3rd, 2015, a playable demo heavily focusing on the Dance of Deduction mechanic was released on Nintendo eShop.

Ken Gyakuten Saiban[]

On April 1, 2015 local time, the official Japanese site for Adventures celebrated April Fools' Day by renaming the game Ken Gyakuten Saiban: Inuhodō Ryūnosuke no Bōken (犬逆転裁判 -戌歩堂龍ノ介の冒險-; lit. "Dog Turnabout Trial: The Adventures of Ryūnosuke Inuhodō") and showing dog-like versions of the main characters. Herlock Sholmes's design as a dog is based on the "Meitantei Holmes" 1984 anime. The first kanji of the title was changed from 大 (meaning "big"/"great"/"large") to the slightly different-looking 犬 (meaning "dog"). Similarly, the first kanji of the Naruhodo surname was changed from 成 (meaning "to accomplish/finish/become") to the slightly different-looking 戌 (the Earthly Branch for the dog). The other characters' names each had a kanji or syllable replaced with ワン (wan, the sound of a dog barking) (Kazuwan Asogi, Susato Mikotowan, Iris Wantson) except Herlock Sholmes, whose name stayed intact. A trailer was also shown, based on the Tokyo Game Show trailer of Adventures.

Unofficial translation[]

Since the game was not initially planned for an official English release, in August 2017 a group by the name of "Scarlet Study" released the first English translation patch for the game. The initial patch translated the first case, with subsequent patches released through late 2017 and 2018 translating cases two, three, four, and five. On March 30, 2019, the full patch was released with all five cases translated.


Famitsu gave Adventures scores of 9/9/9/8 out of 10, for a total score of 35/40.[7] The game sold 135,690 physical units in its first week, surpassed only by Yo-Kai Watch Busters: Red Cat Team & White Dog Corps.[9]


The Adventures soundtrack, Dai Gyakuten Saiban: Naruhodō Ryūnosuke no Bōken Gekiban Ongaku Daizenshū, contains 67 tracks on 2 CDs. It was released on July 15, 2015.

Character Popularity Poll[]
