Steins;Gate 0 (visual novel)

Steins;Gate 0 (シュタインズ・ゲート ゼロ) is a full-length visual novel serving as a midquel to the original Steins;Gate visual novel. It has been marketed as a "true sequel" visual novel as opposed to being a fan disc like the previously-released Steins;Gate: Linear Bounded Phenogram. Zero is part of the main canon and narratively -though not chronologically- takes place before the true ending of the original story as it explores events from the Beta Attractor Field's future that contribute via time travel in making the end of the original story possible. Zero primarily takes place in the Beta Attractor Field, starting in world line divergence 1.129848% and depicting divergences ranging from 1.053649% to 1.382733%, as well as a small glimpse of Alpha Attractor Field 0.571082%. Beta AF 1.130209% was also brought into connection with Zero when it was displayed at the end of the anime episode 23(β) countdown timer shown on December 3, 2015 on the official visual novel website.

It was released in Japan on December 10, 2015 on PlayStation 3, PlayStation 4, and PS Vita , and was ported to Windows PC on August 26, 2016. It was released on February 21, 2017 for Xbox One An anime adaptation of the visual novel has already been green-lit.

PQube released the visual novel in English in regular and limited editions on the PlayStation 4 and PS Vita for Europe on November 25, 2016 and four days later for North America.

Preview description
Zero takes place starting in November 2010 in the Beta Attractor Field outside of the Steins Gate. It depicts the Rintarou Okabe who had given up on saving Kurisu Makise after his first horrific failed attempt. Caught in despair, Okabe abandons his "Hououin Kyouma" persona and is tormented by flashbacks of Kurisu's death and the incidents of the Alpha world lines. The Labmems are worried about him, and at Mayuri's recommendation he begins treatment at a mental health clinic.

His life is stirred up again when, while helping out at a university seminar, he meets Kurisu's professor and research supervisor, Alexis Leskinen, along with Leskinen's assistant, Maho Hiyajo. Kurisu had worked in the same lab as them at Victor Chondria University studying artificial intelligence. From them Okabe learns about the "Amadeus" system, which stores the memory of a human and creates an emulation of that person. His life is changed completely when Leskinen asks Okabe to become a "tester" in interacting with Amadeus and Okabe meets Kurisu's "Memories" held within the system.

As a tester Okabe continues to speak with "Kurisu" using a dedicated smartphone application. As their conversations pile up, like in the past Okabe begins to grow closer. However, Okabe is also filled with anguish.

Other plot points include, the labmems hold Christmas and New Year's celebrations to hearten and cheer Okabe up. The girls dress as Santa Claus and shrine maidens and attention is given to the story of Yuki Amane and Daru and their future daughter Suzuha.

Also, while the Labmems are all gathered, a mysterious masked group bearing firearms attacks the lab, and Okabe is struck by the recollection of Mayuri's many deaths in the Alpha world lines. This is a world line where the PhoneWave no longer exists, and there should be no other reason for SERN to target them, but...

Though it will draw from the Epigraph Trilogy light novels and the stories from various drama CDs, Zero is not a "game-ification" of those stories but will have its own new scenario. Characters not seen in the original visual novel and anime will also be joining the cast, such as Maho Hiyajo, Yuki Amane, Kagari Shiina; Fubuki (Katsumi Nakase) and Kaede Kurushima, Mayuri's cosplay friends; Alexis Leskinen; and Judy Reyes, a professor of physiological psychology.

Gameplay
Zero features a new twist on the "phone trigger" system introduced in the original work. The protagonist Okabe's old mobile phone has been changed to a smartphone, and the story's route can be changed using two applications installed on the new device.

As a tester given access to Amadeus, Okabe is able to communicate with "Kurisu" through a dedicated app, and "Kurisu" is able to contact him at will as well...

Further, in place of the emails from the previous work, a messaging app called RINE, which was developed by Daru, is used to respond to Okabe's friends. Even the digital stickers used in the app are expected to effect the course of the game.



Plot
The story of Steins;Gate 0 consists of fourteen unnumbered sections that are woven together and lead to six endings.

Absolute Zero
Suffering from serious PTSD due to the trauma and tragedy during the summer of 2010, Okabe has given up on trying again to save Kurisu and thrown away his chuunibyou character, Hououin Kyouma. In Nov. 2010, he is helping out at the winter ATF as a serious college student. At the forum he meets Professor Alexis Leskinen and Maho Hiyajo from the same university and brain science research department that Kurisu had been a part of. They give a presentation on Amadeus, a superior AI built using Kurisu’s research on digitizing human memories. By holding a real person’s own memories, Amadeus is able to react to conversation, withhold personally sensitive information, and process ideas in a manner that is seemingly completely natural.

When Leskinen discovers that Okabe had been friends with Kurisu, he offers for Okabe to become a conversation test partner for an Amadeus derived from Kurisu’s own memories. Okabe agrees and five days later he is introduced to Kurisu’s Amadeus. This “Kurisu” has her original’s memories taken from just before the real Kurisu left to study in Japan the previous summer, so “she” has never met Okabe before, but the extreme degree of similarity and life-likeness of “Kurisu” shocks Okabe deeply.
