Stories of the Lab members

This work is adapted from 'STEINS;' GATE's multiple characters unfold their own independent stories from the perspectives of their respective roles. The official website publishes ten stories, including Rintaro Okabe, Itaru Hashida, Kurisu Makise, Suzuha Amane, Yugo Tennoji, Phyllis, Ryuka Urushihara, Mayuri Shiina, and Moe Kiryu; The 2013 PS3/Xbox 360 version also released an unlocked viewpoint called 'Moon Halo no Bivlost.' Each arc presents the characters' troubles, choices, and emotions, including developments within mutually exclusive timelines.

ensemble relationships and emotions

The members of the Future Props Research Institute are not limited to Okabe's actions. Characters like Kurisu, Mayuri, Itaru, and Suzuha each face situations related to time travel, the research institute, or Akihabara; Different perspectives allow players to re-understand their behavior in the original game. Official sources describe these stories as closely connected to the main story and deepening the characters' inner worlds, so the focus is on supplementing the ensemble perspective rather than replacing the original main storyline.

Phone Trigger and chapter unlock

Players control their character's phone in the game, receive emails, and decide how to respond; The official system is called Phone Trigger, explaining that how phones are handled affects the plot's direction. After clearing a chapter, a new chapter appears, and players can choose the reading order. The iOS version also clearly lists mailing lists, terminology prompts, phone personalization, and cross-device iCloud archiving—these are convenient features for this mobile version and should not be applied directly to all home console versions.

Original and Ported Versions

The game was released on April 25, 2013, for PS3 and Xbox 360, followed by a PS Vita version; MAGES. Official Record iOS version was released on September 25, 2014, and features ten episodes, full voice, and over 20 hours of content. The Nintendo Switch version was included in the 2019 'STEINS;' GATE Divergencies Assort collection. The above platform versions carry the same spin-off story, but the touchscreen controls, save files, and collection formats belong to their respective versions.

Perspectives of different characters

The official website publishes ten standalone stories, narrated not only from Okabe but also from the perspectives of research institute members and Yugo Tennoji. In the 2013 PS3/Xbox 360 version, after these chapters, you can unlock the middle school student perspective 'Moon Halo no Bivlost.'

Hashida's post tracking and Moeyu's orders

In the 2013 original version of 'Femme Fatale,' Hashida tracks the mysterious note and bomb message posted by Chopstick Girl on @channel, discovering Yuki Amane being detained by Rounder. "Coma Excitation Quantam" depicts from Mengyu's perspective of FB sending her to monitor the lab, then ordering sabotage, sowing discord, and killing members; Her interactions with Kurenai Risu and Mayuri make it difficult to carry out orders.

Mayuri and Yuruka each made their own decisions

In 'The Unchanging Polaris,' Mayuri learns that Kurisu must sacrifice herself, so she sends a D email to change her childhood and enters a world she never met with Okabe; Okabe, who still retains his memories, eventually finds her. "Labyrinth Complex Helma Floditos" is a different development for the woman Ruka facing Mayuri's death. She requests a time jump, hoping to at least fulfill the wish of seeing her cosplay.

Suzuha, Phyllis, and Akihabara

In 'Ghost Disorder Rendezvous,' Rain damages the time machine, and Suzuha encounters two versions of herself in military uniforms and maid outfits. With Hashida's help, she gains time to spend with her father. In 'Peach-Colored Phantom City of Sha Noir,' Phyllis and Suzuha investigate ghost stories and discover that they are self-written projects by the shopping street promotion organization; Without consulting her, the adults told her they would leave Akihabara, leaving her feeling down.

The fathers and Kurisu seeking help

In 'Scraper of the Rainy Bell,' Yugo wins a prize of 300 million yen to rebuild a building for his daughter, but Tao loses it after completion; Okabe suggested starting over with D Mail. In 'Twilight Colored Saucer,' Kurisu seeks help from Felis's father, Yukitaka Akiba, but is still unable to reverse the news of Mayuri's death. Later, she receives a call from her father, Shoichi Makise.

Two chapters of Okabe

"Jekyll on the Scan Line" had Okabe wear an alpaca man-suited made by Mayuri, using D-mail and time jump to handle street incidents; Kuri Lixi visits in mourning clothes, forcing him to face a death he refuses to admit. In 'Abduction of Cause and Effect in Three Lifetimes,' he repeatedly altered the world line to address Mayuri's disappearance, laboratory fire, and bloodstains, merging clues from the three worlds together.

Hidden threading points

In addition to the ten stories released in the 2013 PS3/Xbox 360 original, there is also the unlocked 'Moon Halo Vivlost'. It unfolds from the perspective of middle school student Nao, set in a α world after Mayuri and Yugo have died, and after Okabe and others are taken away by SERN, it depicts the loneliness she feels in the face of previous events.

Short versions of the original soundtrack and piano versions

FVCG-1247, released on July 3, 2013, features the radio program on DVD and 24 tracks of the original soundtrack on CD. Tracks 1, 23, and 24 each feature short versions of 'Phenogram,' 'Paradise Hologram,' and 'Memories of That Summer Day.' "Distress for you" and "GATE OF PHENOGRAM" each have separate piano versions, and the playlist includes ten tracks themed around Ringing. The opening short edition features lyrics and music by Chiyomaru Shikura, arranged by Obako Suke; The short edition of 'Hologram of Paradise' features lyrics by Junya Urushino, music by Etsuhiro Suda, and arrangement by Toshimichi Isoe; Another short version of the ending song features lyrics by Chiyomaru Shikura, composed and arranged by Kosuke Oshima.

Sound quality and high-resolution production with a unified worldview

In an interview, Abao Gang said that when composing, he took into account that this work shares a worldview with Steins;Gate, so the music from one work fits naturally into another. From the start, the music for "Linear Constraint" was produced entirely at 48kHz, with about 60% 16bit and 40% 24bit. When processed to 96kHz/24bit, the tone changes noticeably, especially in physically modeled audio sources. The FPBD-0340 high-resolution catalog, released on September 30, 2015, contains 30 tracks, with 24 tracks listed after the tracklist featuring Darling BGM 001 to 006.

The preparation of the theme song differs between the two versions

When Ayane recorded the original PS3 theme "Phenogram," the game was still in development, and she understood the world based on limited information. By the time the PS Vitamin added the OP recording "Encounter no Fetalitet," she was already playing the game; The song also includes the production process of adjusting lyrics during recording and changing the melody in the final chorus.
