Robotics;Notes

Robotics;Notes is a visual novel video game developed by 5pb. It is the third main game in the Science Adventure series, following Chaos;Head and Steins;Gate, and is described by the developers as an "Augmented Science Adventure". The game was originally released by 5pb. in Japan on the PlayStation 3 and Xbox 360 in 2012; the enhanced version Robotics;Notes Elite was released for PlayStation Vita in 2014, and for Nintendo Switch and PlayStation 4 in 2019. An English version of Robotics;Notes Elite was released by Spike Chunsoft in 2020 for Microsoft Windows, Nintendo Switch and PlayStation 4.

Six manga have been produced, and an anime adaptation by Production I.G aired in Fuji TV's Noitamina slot between October 2012 and March 2013. The anime has been licensed by Funimation in North America. Robotics;Notes DaSH, a sequel to the game, was released in 2019.

Gameplay
Robotics;Notes is a science fiction visual novel in which the player follows the perspective of multiple characters, mainly Kaito Yashio. Its gameplay requires little player interaction as much of the game's duration is spent on reading the text that appears on the screen, which represents the story's narrative and dialogue. The text is accompanied by 3D animated character models, which represent whom Kaito or Akiho is talking to, and background art. Throughout the game, the player encounters CG artwork at certain points in the story, which take the place of the background art and character models. Unlike the previous entries in the Science Adventure series, Robotics;Notes follows an almost entirely linear narrative, consisting of twelve chapters referred to as 'phases'. Depending on the decisions made at certain points during the game, the player can choose to skip some phases entirely.

Throughout the narrative sequences in which the player follows Kaito, the player may activate the PokeCom Trigger (ポケコントリガー), which replaces Steins;Gate Phone Trigger system and allows the player to use the applications installed on Kaito's tablet computer. These applications include Deluoode Map, a map application; Twipo (ツイぽ), a Twitter-like social networking application, which the player may use to reply to other characters' tweets with predetermined responses; and Iru-o (居る夫.), an augmented reality image recognition application which the player may use to examine the environment and information tagged on characters or objects.

Setting and themes
Robotics;Notes is set in 2019 on Tanegashima, an island to the south of Kyūshū in southern Japan. The game's theme is robots and the question "What would happen if you really tried to make a giant robot?"

Story
In Robotics;Notes, the player assumes the role of Kaito Yashio, someone who enjoys fighting games. He is in his school's robot club along with his childhood friend Akiho Senomiya. The story begins when Akiho decides to build a robot based on the Gunvarrel animated series she is a fan of, and she recruits Kaito to aid her. With the robot club short on members and on the verge of closure, Kaito heads out to try and recruit more members, eventually securing the support of professional robot battler Subaru Hidaka, karate practitioner Junna Daitoku, and the world renowned programmer Frau Kojiro. Together, they begin the process of building their replica of the titular Gunvarrel, the Gunbuild-1. However, reality quickly sets in when they realize the physical impossibility of completely replicating Gunvarrel, and are forced to make many design compromises. In addition to the relatively primitive Gunbuild-1, they also manage to build the more advanced Gunbuild-2. They also take advantage of the Iru-O system to change both Gunbuilds' appearances via augmented reality.

As Gunbuild-1 is being developed, Kaito also comes across the "Kimijima Reports", authored by the deceased scientist Kō Kimijima who claims an impending solar flare will wipe out all life on Earth. Kaito also encounters two AI personalities that inhabit Iru-O, Airi and Sister Centipede, who help him track down the other reports. Kaito follows the instructions in the reports in an effort to avert the solar flare, and in the process wakes up Airi Yukifune, the girl the AI Airi is based on, who was put into suspended animation due to a then incurable illness. However, Kaito discovers too late that the reports were a lie, and that it is Kimijima himself, now an AI living within the Iru-O system, attempting to trigger a solar flare on the behalf of the Committee of 300 in plan dubbed "Project Atum".

Moving on to the next stage of his plans, Kimijima deletes Airi and seizes control of Akiho's older sister Misaki, stealing an experimental battle robot called SUMERAGI and destroying the Gunbuild-2. Meanwhile, the Committee of 300 orchestrates mass robot rebellions all over Japan, plunging the country into chaos while a commando team seizes the Tanegashima Space Center with the help of SUMERAGI. The robotics club is then approached by Nae Tennouji and Toshiyuki Sawada, who reveal they are part of a secret group that resists against the Committee of 300, and that the Committee plans to use Tanegashima to launch a rocket containing bombs that will create a apocalyptic solar flare that will wipe out the majority of humanity, allowing the Committee to rule over the survivors and rebuild the world according to their will. Sawara provides the robotics club with a special code that can completely delete Kimijima, but requires them to be in close range to send it. Working together with the other Tanegashima residents, the robotics club upgrades Gunbuild-1 into the Super Gunbuild-1 and Kaito pilots it against SUMERAGI while Nae neutralizes the commandos. Kaito is able to force Misaki to exit her cockpit, leaving Kimijima vulnerable and allowing Kaito to delete him, though Kimijima boasts that another copy of himself will surely surface.

With Kimijima gone, Nae is able to abort the rocket launch and thwart the Committee's plan. The robotics club is then greeted by the Tanegashima residents who celebrate them as heroes.

Development and release
The planning and original concept and basic story of Robotics;Notes was headed by Shikura. Naotaka Hayashi is the scenario writer for the game and Tatsuya Matsubara the producer. The character designs are done by Tomonori Fukuda and the mechanical designs are done by Makoto Ishiwata. The composer of the game is Takeshi Abo. Shikura had been working on the game as early as July 2010. The team received development support from the Japan Aerospace Exploration Agency,   and according to Shikura, this allowed the game's sciences and themes to better reflect reality. Nitroplus also provided assistance with the game. Robotics;Notes features 3D visuals, and the development team were aiming for high quality 3D models like Catherine and Idolmaster 2. The game is described by the developers as an "Augmented Science Adventure" (拡張科学アドベンチャー).

Robotics;Notes was announced through 5pb.'s official website on December 22, 2010, noting that details about the game would appear in the interview with Chiyomaru Shikura, the CEO of 5pb., featured in the issue of Famitsu magazine that was being sold on the same day. Robotics;Notes is the third entry in the Science Adventure series following the release of Chaos;Head in 2008 and Steins;Gate in 2009. When the target platform for the game had not yet been announced, Shikura had said that they were not going to let down the fans who have supported their past works in the Science Adventure series. He also stated that said they were aiming for a release some time in 2011. The game was released for both the PlayStation 3 and Xbox 360 on June 28, 2012. The PlayStation 3 version allows support for Remote Play with the PlayStation Vita. A PlayStation Vita port was released on June 26, 2014 under the title Robotics;Notes Elite, adding new features and animated scenes. Characters in the enhanced version were remodeled, and new animated video scenes were added. A Nintendo Switch version of Robotics;Notes Elite was announced by Shikura through a live stream in 2018; both it and a PlayStation 4 version were released on January 31, 2019, as Robotics;Notes Elite HD in a double pack with the sequel Robotics;Notes DaSH.

In 2018, Shikura said that a Western release of the game was under consideration; English versions of Elite and DaSH were announced by Spike Chunsoft at Anime Expo 2019, and were released worldwide for Microsoft Windows on October 13, 2020. The PlayStation 4 and Nintendo Switch versions were released in a bundle, on the same day in North America and on October 16 in Europe.

Reception
Famitsu gave the PlayStation Vita port Robotics;Notes Elite a review score of 30/40. Japanese pre-orders for the original release of the game were over 80,000, a large increase over the preorders for Steins;Gate, the previous game in the series. Neither Famitsu nor Media Create revealed sales numbers for the DaSH and Elite HD bundles for PlayStation 4 and Nintendo Switch as part of their weekly sales charts, although Media Create listed both as ranking higher than the Nintendo Switch stand-alone version of DaSH, which sold 2,834 physical copies. Martin from the English Science Adventure news site Kiri Kiri Basara rated Robotics;Notes Elite an 8/10 for its "nearly flawless" story, but noted poor structure and various localization and technical issues in the English release, recommending a fan patch to improve the experience on the Windows release.
