# Steins;Gate

Steins;Gate is a 2009 science fiction visual novel game developed by 5pb. and Nitroplus. It is the second game in the Science Adventure series, following Chaos;Head. The story follows a group of students as they discover and develop technology that gives them the means to change the past. The gameplay in Steins;Gate includes branching scenarios with courses of interaction.
Steins;Gate was released in Japan for the Xbox 360 in October 2009. The game was ported to Windows in August 2010, PlayStation Portable in June 2011, iOS in August 2011, PlayStation 3 in May 2012, PlayStation Vita in March 2013, and Android in June 2013. JAST USA released the PC version in North America in March 2014, both digitally and as a physical collector's edition, while PQube released the PS3 and Vita versions in North America and Europe in 2015. Additionally, the iOS version was released in English in September 2016. The game is described by the development team as a speculative science ADV.
A manga adaptation of the game, created by Yomi Sarachi, was serialized from 2009 to 2013, and later published in North America from 2015 to 2016. A second manga series, illustrated by Kenji Mizuta, began serialization in Mag Garden's Monthly Comic Blade in December 2009. An anime series adaptation by White Fox aired in Japan between April and September 2011, and has been licensed in North America by Funimation. An animated film premiered in Japanese theaters in April 2013. A fan disc of the game, titled Steins;Gate: My Darling's Embrace, was released in June 2011. A non-canon 8-bit sequel to the game, titled Steins;Gate: Hen'i Kuukan no Octet or Steins;Gate 8bit, was released in October 2011. Another game, Steins;Gate: Linear Bounded Phenogram, was released in April 2013.
A follow-up game, Steins;Gate 0, was released in December 2015, for PS3, PlayStation 4 and Vita, and received an anime adaptation in 2018. A remake of the original visual novel titled Steins;Gate Elite which presents fully animated cutscenes from the Steins;Gate anime was released for PlayStation 4, PlayStation Vita, Nintendo Switch and Steam in 2019. Included as a bonus for the Nintendo Switch version, an entirely new game called 8-bit ADV Steins;Gate in the style of Famicom adventure games from the 1980s, was released.
Another remake, titled Steins;Gate Re:Boot, was officially announced in October 2024 with a release date of 2025.

## Gameplay

Steins;Gate's gameplay requires little interaction from the player as most of the duration of the game is spent reading the text that appears on the screen, which represents either the dialogue between the various characters or the thoughts of the protagonist. Like many other visual novels, there are specific points in Steins;Gate where the user is given a choice to affect the direction of the game. For these decision points, Steins;Gate presents the user with the "phone trigger" (フォーントリガー, fōn torigā) system. When the player receives a phone call, the player can choose to answer or ignore the call. Incoming text messages have specific words underlined and highlighted in blue, much like a hyperlink on a browser, which the player can select to reply to the text message. Most phone calls or text messages do not require a response, though there are certain points in the game where the player is required to take action. Depending on the player's choices of how to respond to these phone calls and text messages, the plot will progress in a specific direction.

## Synopsis
### Setting and themes

Steins;Gate is set in the summer of 2010, approximately one year after the events that took place in Chaos;Head, in Akihabara. Physical locales of Akihabara like the Radio Kaikan building can be spotted in the game. According to Chiyomaru Shikura, who headed the planning of Steins;Gate, Akihabara was chosen because it is an easy place for acquiring hardware parts, which makes it the ideal place for people interested in inventing and tinkering with things. The notion of time and time traveling are the main themes of the game. The concept of cause and effect is featured prominently in the game as the protagonist travels back in time numerous times to perform different actions in an attempt to alter what has happened in the future. Steins;Gate also features hard science fiction elements.

### Characters
#### Okabe "Okarin" Rintaro (岡部 倫太郎, Okabe Rintarō)

    The player assumes the role of Okabe Rintaro, the protagonist of Steins;Gate. Rintaro is an eccentric individual, a self-proclaimed mad scientist who often goes by the pseudonym Hououin Kyouma (鳳凰院 凶真, Hōōin Kyōma). Mayuri and Daru call him "Okarin" (オカリン), a portmanteau of his surname and given name. He is 18 years old and a first-year student at Tokyo Denki University, alongside being the founder of what he calls the "Future Gadget Laboratory" (未来ガジェット研究所, Mirai Gajetto Kenkyūjo) in Akihabara, where he spends most of his time and has dubbed himself Lab Member No. 001 (as he is the first person to join). Rintaro gives off the appearance of being delusional and paranoid, frequently referring to the "Organization" that is after him, talking to himself on his phone, and engaging in fits of maniacal laughter. He is frequently mocked for this behavior, mostly by Kurisu and Itaru, and referred to as a chunibyou, although as the story progresses, he mellows out and shows that deep down he is a kind-hearted and loyal friend, only playing up the Hououin Kyouma personality as both a form of entertainment and a way to guise his insecurities. As he experiments with time travel, he learns that he is the only one who possesses the ability to determine changes between different timelines, which he dubs "Reading Steiner"; the reasoning behind this is never explained in-universe, although it is implied that a fever he had as a child during the Y2K crisis had something to do with it.

#### Makise Kurisu (牧瀬 紅莉栖)

    Makise Kurisu is the main heroine of the game and Lab Member No. 004. She is an 18-year-old neuroscience researcher at an American university who can speak and read English well. Having had her research published in the academic journal Science at this age, Kurisu is extremely talented. She had skipped a grade in the American school system. Rintaro simply tends to call her assistant (助手, joshu) or one of the several nicknames he comes up with, such as "Christina" (クリスティーナ, Kurisutīna), "the Zombie", and "Celeb Sev", which bugs her to varying degrees. She is something of a mild tsundere, although she will object to it whenever someone (usually Itaru) calls her that. She does not get along with her father and has not spoken to him in many years. She posts on @chan (the game's in-universe version of 2channel) under the name "KuriGohan and Kamehameha"; the alias also makes a cameo on Kaito Yashio's PokeCom tablet in episode 9 of Robotics;Notes.

#### Shiina "Mayushii" Mayuri (椎名 まゆり)

    Shiina Mayuri is a long-time childhood best friend of Rintaro and is a bit of an airhead, as well as Lab Member No. 002. Mayuri enjoys creating cosplay costumes and has a part-time job at a maid café called "MayQueen NyanNyan". She often calls herself Mayushii (まゆしぃ), a portmanteau of her given name and surname, which is also what Itaru calls her. She has a distinctive sing-song way of speaking, and she typically sings tutturū (トゥットゥルー) when she arrives or introduces herself. Several years prior she lost her grandmother under unknown circumstances, and to prevent her from succumbing to grief, Rintaro declared her his "hostage", his entire eccentric persona being for her sake. She is 16 years old and she is a second-year at a private university preparatory school.

#### Hashida "Daru" Itaru (橋田 至, Hashida Itaru)

    Hashida Itaru is an experienced hacker who has known Rintaro since high school and is Lab Member No. 003. He is very skilled in computer programming and with old and new computer hardware. He is also well-versed in things on otaku culture. Rintaro and Mayuri refer to him by the nickname "Daru" (ダル), a portmanteau of his given name and surname. Rintaro sometimes also calls him Super Hacka (スーパーハカー, Sūpā Hakā) (Hack in the English dub), mispronouncing the word "hacker" (ハッカー, hakkā) to his chagrin. He is attracted to Faris and frequently sexually harasses her. Itaru is often annoyed with Rintaro's frequent delusional behavior. He is 19 years old and, like Rintaro, is a first-year student at Tokyo Denki University. He appears in Robotics;Notes as DaSH, and as a main character in its sequel, Robotics;Notes DaSH.

#### Kiryu Moeka (桐生 萌郁)

    Kiryu Moeka is a tall girl who Rintaro bumps into in Akihabara and is on a search for the IBN 5100 personal computer, and is Lab Member No. 005. Moeka is extremely protective of her mobile phone and becomes agitated if someone tries to take it from her hands. She is very shy and prefers to talk to someone by sending them a text message instead of speaking, even if they are right in front of her. Okabe calls her Shining Finger (閃光の指圧師（シャイニング・フィンガー）, Shainingu Fingā). She is 20 years old.

#### Urushibara Luka (漆原 るか, Urushibara Ruka)

    Urushibara Luka is a friend of Okabe and Lab Member No. 006. His appearance and mannerisms are quite feminine as a result of his upbringing, wearing girl's clothing within and outside his father's temple, leading to the implication that Luka may be transgender. He is also a close friend and classmate of Mayuri, who often asks him to try on her cosplay costumes, but as he is quite shy, he generally refuses. Okabe calls her by a feminine nickname Rukako (ルカ子), and thinks of Luka as his pupil. He is 16 years old.

#### Faris NyanNyan (フェイリス・ニャンニャン, Feirisu NyanNyan) / Akiha Rumiho (秋葉 留未穂, Akiha Rumiho)

    Faris NyanNyan works at the maid cafe "MayQueen NyanNyan", the same maid cafe that Mayuri works at, and is the most popular waitress there, as well as Lab Member No. 007. Her real name is Akiha Rumiho. Her family owns Akihabara, and she was the driving force behind it becoming the city of moe and anime. She tends to add "meow" (ニャン, nyan) to her sentences. She is 17 years old.

#### Amane Suzuha (阿万音 鈴羽)

    Amane Suzuha works part-time for the landlord of Rintaro's apartment and is on a search for her father in Akihabara, and is Lab Member No. 008. She enjoys riding her bicycle and appears to be at odds with Kurisu for some reason. Later it is discovered that she is actually the time traveler from the future that was under the guise of John Titor, and is the future daughter of Itaru, her real name being Hashida Suzu (橋田 鈴, Hashida Suzu). She is 18 years old. She is the main protagonist of the side-story manga, Steins;Gate: Bōkan no Rebellion.

#### Tennouji Yugo (天王寺 裕吾)

    He is Okabe's landlord, who owns a TV repair store beneath his apartment, living with his daughter, Nae. Rintaro gives him the nickname "Mr. Braun" due to his passion for CRT TVs (known in Japan as "Braun-tube TVs"). He is usually rough and impatient, especially when interacting with Rintaro, but acts dotingly over his daughter and his TVs. He is the protagonist of the side-story manga, Steins;Gate: Onshū no Braunian Motion.

#### Tennouji Nae (天王寺 綯)

    Yūgo's daughter who lives with him in the TV repair store and gets along well with Mayuri and Suzuha, but is afraid of Rintaro. She later appears in Robotics;Notes as a member of JAXA.

#### Doctor Nakabachi (ドクター中鉢)

    Kurisu's father and the supreme antagonist of the series. His obsession to outshine his daughter in the field of science ends up leading into World War III. His real name is Makise Shoichi (牧瀬 章一).

### Plot
#### True End route

The following summary is based upon the True End route.
Steins;Gate takes place in the Akihabara district of Tokyo. On July 28, 2010, Okabe Rintaro and his friend Shiina Mayuri head towards the Radio Kaikan building for a conference, where Rintaro finds a girl named Makise Kurisu lying in a pool of blood. As Rintaro sends a text message about the incident to his friend, Hashida "Daru" Itaru, he experiences a strange phenomenon and the people around him disappear, with no one else noticing anything had changed. After later running into Kurisu, who is strangely alive and well, and discovering the message he had sent to Itaru had arrived a week before he sent it, Rintaro soon deduces that the 'PhoneWave' he and his friends had been developing is, in fact, a time machine capable of sending text messages to the past. He and his friends soon learn that SERN, an organization that has been researching time travel for some time, has actually succeeded in sending humans into the past, although they seem to have all resulted in the test subjects' deaths. Rintaro begins experimenting with "D-Mails" (Dメール, D mēru, short for DeLorean mail), which begin to cause major differences in the timeline. Kurisu also manages to create a device to send a person's memories through the microwave, allowing that person to effectively leap into the past.
However, SERN learns of the time machine and sends a group led by Moeka to retrieve it, killing Mayuri in the process. Using Kurisu's time leap machine, Rintaro travels back in time numerous times to try to save Mayuri, but to no avail. As Rintaro reaches wit's end, he is approached by Amane Suzuha, a girl from a future ruled by SERN due to their possession of a time machine, who tells him that he needs to return to a Beta worldline in which Mayuri won't die. By undoing the effects of the D-Mails that caused shifts in the timeline, Rintaro regains possession of an IBN 5100 PC that they lost earlier, allowing them to crack into SERN's systems and delete the evidence of Rintaro's original D-Mail. However, Rintaro realizes that by doing so, he would have to return to a world line in which Kurisu is dead. After realizing their feelings for each other, Kurisu tells Rintaro to save Mayuri. Reluctantly, Rintaro agrees and deletes the evidence of his D-Mail from SERN's database, returning him to the Beta world line, where Kurisu died as she did at the start of the story, and the rest of the cast, sans Rintaro, do not remember that anything had happened.
A couple days later, an alternate world line variant of Suzuha appears before Rintaro, having arrived in a time machine from the future. She tells Rintaro that the only way to prevent World War III in the future is to prevent Kurisu's death at the hands of her father, Dr. Nakabachi, who stole her time travel theory to publish it under his own name. However, this operation ends in a disaster as Rintaro ends up killing Kurisu himself by mistake. After this failure, Rintaro receives a message from his future self, telling him that the way to save Kurisu without altering the events that led to him developing a time machine is to fool his past self into believing Kurisu had been killed and thus achieving the final divergence value of 1.048596%, which he dubs 'Steins Gate'. Returning to the past again, Rintaro puts his own life in danger in order to save Kurisu's life, prevent Nakabachi from successfully escaping with the time travel theory, and fool his past self, setting him on his journey through time. After this, Rintaro returns to the Steins Gate world line, safe from the threat of a third world war. Later, Rintaro and Kurisu manage to reunite by chance (or by fate) in the streets of Akihabara, with Kurisu appearing to possess some lingering memories of their history together.

#### Alternate endings

The player's choices throughout the game may result in alternate endings.
* In the Amane Suzuha Ending, Okabe decides to not send the D-Mail that would prevent him from pursuing Suzuha. To prevent Mayuri's death, he re-lives the final two days before her murder through constant time-leaping. After countless leaps, Okabe loses all emotion and personality due to re-living the same two days for all eternity. Eventually, Suzuha notices Okabe's behavior. She tells him that he will slowly "die" on the inside, and the world's set divergence will continue as planned. Both of them decide to travel to the past together and vow to stop SERN's dystopian future, despite the possibility of both losing their memories on arrival.
* In the Faris NyanNyan Ending, Okabe decides to not send the D-Mail that results in the death of Faris's father to try to stop the loss of the IBN 5100 computer. He instead sends a different D-Mail in an attempt to convince Faris's father to not part with the IBN computer. Beyond 1% divergence is achieved, but the divergence meter gives a strange output and none of Okabe's friends have any memories of him. In this worldline, Okabe and Faris are a couple and live together, participating in RaiNet Access Battlers card game tournaments. Although disappointed that none of his friends remember him, Okabe is still satisfied that he was able to prevent Mayuri's death. He decides to build a new life with Faris at his side.
* In the Urushibara Ruka Ending, Okabe decides to not send the D-Mail that reverts Ruka to a guy. He fully accepts Mayuri's expected death and makes no more attempts to save her and they spend the last two days together before she dies of a heart attack. Okabe and Ruka decide to spend the rest of their lives together, both of them sharing a pang of guilt and sadness that only they would understand. In a post-credit scene they are revealed to now have a child together.
* In the Shiina Mayuri Ending, Okabe must choose between saving Mayuri or Kurisu. Realizing that he harbors romantic feelings for Mayuri, Okabe and Kurisu decide to return to the Beta worldline in which Kurisu's murder continues as planned. After hacking into SERN's database with the IBN computer, a 1% divergence is achieved. Okabe vows to remember his memories of Kurisu and spends his time with Mayuri as lovers.
* The Makise Kurisu Ending follows a similar route to the True End. To achieve this ending, one must have had several conversations with Kurisu throughout the game. Doing so allows Okabe and Kurisu to realize their inner feelings for each other. Unlike the True End, Kurisu's death is not prevented after the credits; Suzuha never returns and it is implied that this world will eventually meet the fate of World War III.

## Production
### Development

Steins;Gate is the second collaborative work between 5pb. and Nitroplus after Chaos;Head. The game was created with the concept of "99% science and 1% fantasy" in mind. The planning for Steins;Gate was headed by Chiyomaru Shikura of 5pb. The characters were designed by Ryohei Fuke, also known as 'Huke' (one of the illustrators of the Metal Gear series, and the creator of the Black Rock Shooter franchise) whereas the gadgets were designed by Sh@rp. Naotaka Hayashi of 5pb. wrote the scenario with assistance from Vio Shimokura of Nitroplus. Tatsuya Matsuhara from 5pb. was the producer and Tosō Pehara from Nitroplus was the art director. The music was composed by Takeshi Abo of 5pb. and Toshimichi Isoe of Zizz Studio. Shikura, Hayashi, Matsuhara, Abo, and Isoe had all previously worked on Chaos;Head. The title "Steins;Gate" had no specific meaning, being coined from the German word "Stein" meaning stone, and tying in with famous physicist Albert Einstein. Matsuhara, who came up with the concept of the phone trigger system, stated that he initially wanted to incorporate the player's own mobile phone into the system. However, the idea was abandoned due to concerns that it might clash with Japan's privacy laws. When asked if the phone trigger system would be used in a possible sequel to the game, Hayashi stated that he hoped this would not be the case and recalled saying "who thought of this system!" while writing the contents of the text messages. While Shikura did not directly contribute to the script itself, Hayashi stated that Shikura helped with the overall plot and provided assistance with the second half of the story. In particular, Shikura helped a lot with the time-traveling aspects of the story. Hayashi stated that while he did not want the script to repeat the same text over and over again, it was ultimately unavoidable due to the player having to travel back in time so he tried to emphasize the overall tempo of the plot's development and how the plot unfolded. With regards to the theme of time traveling, Hayashi had felt that it seemed like an overdone topic and expressed concern over it when he first heard the idea from Shikura.
Prior to the game's announcement, a teaser site was featured on 5pb.'s website that simply referred to the game as Project S;G and stating that it was going to be a collaboration between 5pb. and Nitroplus. Nitroplus's website had also hinted at this on its 10th anniversary website. Matsuhara, who was also the producer for Chaos;Head, had previously stated that the game would be centred on Akihabara and that the project with Nitroplus would be the second part in a series around the theme "Science Novels (科学ノベル, Kagaku Noberu)". On June 12, 2009, the countdown expired and the name Steins;Gate was revealed. Kana Hanazawa stated that she was happy to have been selected to be in Steins;Gate as she felt that it was not common to be able to play a part in a serious game. She also thought that the game gives the player more of a thrilling sensation rather than a frightening one and it entices the player to continue reading.

### Inspiration

Steins;Gate was inspired by earlier visual novels written by Hiroyuki Kanno. These include Eve Burst Error (1995), and most notably the time-travel adventure YU-NO: A Girl Who Chants Love at the Bound of this World (1996).

### Reviews

In 2009, the Famitsu Awards gave Steins;Gate visual novel an annual Game of Excellence award. In 2011, it was voted #6 in Famitsu's poll of "most tear-inducing games" of all time. Steins;Gate was nominated for the 2015 Golden Joystick Award in the "Best Handheld / Mobile Game" category. In 2017, Famitsu readers voted it the best adventure game of all time.
Senji Ishii of Famitsu Xbox 360 praised the scenario for its detail and noted that events that were overlooked as insignificant later returned to affect events of the future. Due to the way the plot ties the many different events of the game together, Ishii believes it must have been a lot of work to write the scenarios. 4Gamer.net commented that Steins;Gate is comparable to 428: Shibuya Scramble and felt that it is a gem that has not been seen in recent years. ITmedia Gamez noted that players should be attentive to all the details in the story as the twists will surprise the player in many different ways. It was also suggested to the player that the characters' voices be left turned on as the voice acting is very good. The review did caution that players who have played through the demo and who did not enjoy the atmosphere of the game were not likely to find the rest of the game interesting. Steins;Gate has also been praised by Square Enix producer Tomoya Asano, who described it as having "appealing and likable characters and a scenario that surprised players"; this led to Steins;Gate writer Naotaka Hayashi writing the plot and characters for the role-playing video game Bravely Default: Flying Fairy.
The later English release of the Steins;Gate visual novel has also been well received. On Metacritic, it is the seventh highest-rated PC game of 2014, and the highest-rated PS Vita game of 2015. USgamer also gave it a perfect 5 out of 5 stars, concluding that it makes "excellent use of the visual novel medium to tell its story" and "is a beautifully crafted piece of interactive fiction that blends character drama, sci-fi and critique of popular culture into a compelling and memorable whole." GameFan praised the plot as "outstanding", "well written" and "the best storyline in a game released this year, period." They stated the "twists and turns, branching plot points, multiple endings and plot development is amazing" and "an interesting phone-based choice system makes the game feel far more engaging than similar games in the genre". Dealspwn praised the plot, characters, artwork, "excellent" writing and localisation, and the phone trigger system for giving "real choices with huge consequences", and mentioned its technical jargon. GamesMaster said it was smart, "with an unforgettable protagonist", and is one "of the great visual novels." Syfy called it one "of the best Visual Novels of all time," stating that, while "bad guys exist," "by trying to save the future, you become one yourself", making "choices whose devastating consequences you couldn't predict." Official PlayStation Magazine said "it's a story you'll want to see through." Meghan Sullivan of IGN gave it a generally favorable review, praising the story, characters, choices, and endings.

### Video games

The success of Steins;Gate spawned additional sequels. Steins;Gate: Hiyoku Renri no Darling was released on June 6, 2011, and is similar to Chaos;Head Love Chu Chu! in terms of style. The story for this sequel is unrelated and non-canon to the original game, and is more comedic in tone. It was originally an Xbox 360 exclusive, though ports later followed for PS3, PSP, and PlayStation Vita. A version for iOS was later released on October 3, 2013 as well. Another game, Steins;Gate: Linear Bounded Phenogram, was released on April 25, 2013.
Steins;Gate: Hen'i Kuukan no Octet is a non-canon extension of the True End of the original game. Unlike the modern visual novel format of the original game, this retro game mimics the style of graphical text adventure games from the 8-bit PC era (e.g. PC-88), with the player typing short commands to interact with and explore the game world. It features all backgrounds and characters drawn in a low-color pixelated style with emulated scanlines, and chiptune music played through an emulated FM chip with no voice acting. The premise of the game features Okabe Rintaro receiving a D-Mail from himself in 2025 that states that he must save the future by reclaiming an IBN 5100 from a person under the alias "Neidhardt". This person is Takumi Nishijō, the protagonist of Chaos;Head, as he runs under the same player name in his favorite MMORPG, and the D-Mail stating that "Neidhardt" lives in Shibuya and has "inherent, supernatural abilities", a reference to his power as a megalomaniac.
