Steins;Gate — World Line Zero: An Interactive Narrative Experience | Neta Studio

Steins;Gate — World Line Zero

This is not the story of a mad scientist who triumphed against fate. This is the story of the one who failed. The Beta world line — divergence 1.129848% — is the timeline where Okabe Rintaro could not save Kurisu Makise. Where he returned to a present scarred by war, where SERN's dystopian future creeps closer with every passing day, and where the Third World War is not a possibility but an inevitability written into the fabric of time itself.

Welcome to Steins;Gate: World Line Zero, an interactive narrative that plunges you into the emotionally devastating heart of the Beta Attractor Field. This is the road not taken in the original story — the path of grief, guilt, and the slow, painful rebirth of hope. Every choice you make ripples across the world line, altering memories, relationships, and the very course of history. Can you find a way forward when the future you sacrificed everything to prevent is already here?

About This Experience

In the original Steins;Gate timeline, Okabe Rintaro traveled across countless world lines, sacrificing his sanity and his happiness to reach the fabled Steins Gate — a world line where both Kurisu Makise and Mayuri Shiina could live. But in World Line Zero, that journey failed. Okabe returned to a Beta world line where Kurisu is dead, where the Committee of 300 tightens its grip on the world, and where time travel has been weaponized by forces that see history as something to be conquered rather than preserved. The Okabe you guide here is not the confident, charismatic Hououin Kyouma. He is a young man hollowed by trauma, haunted by the screams of a woman he could not save, and convinced that any attempt to change the world line will only make things worse.

This interactive experience adapts and expands upon the narrative framework of Steins;Gate Zero, the canonical story of the Beta world line. You will walk alongside Amadeus — an artificial intelligence built from Kurisu's memories, housed in a digital cage of code and neural networks. You will face the impossible choice between honoring the dead and risking everything to rewrite the past. You will meet characters transformed by war and loss: Daru, now a hardened hacker fighting a shadow war against SERN from his basement; Mayuri, carrying secrets she cannot share; and new faces who will challenge everything you thought you understood about the Steins;Gate universe.

The narrative unfolds through a branching, choice-driven structure where your decisions carry real weight. Send a D-mail to the past and watch as the world line divergence number shifts before your eyes. Choose to push forward or retreat into denial, to trust an AI or to fear it, to fight for a better future or to accept a broken present. Every path reveals new fragments of the story, and no single playthrough will show you everything. Hidden routes, coded messages, and alternate endings await those willing to explore every corner of the Beta Attractor Field.

Game Features

• World Line Divergence Meter — Every decision you make alters the world line divergence number in real time. Track your position across the Attractor Fields as your choices send ripples through the fabric of causality. Small changes can cascade into radically different futures.

• Amadeus System — Interact with an AI constructed from Kurisu Makise's cognitive architecture. Your conversations with Amadeus shape her development, unlock hidden memories, and influence whether she remains a ghost in the machine or becomes something more.

• Branching Narrative with Multiple Endings — Over a dozen distinct endings, from the despair of reaching a world line beyond salvation to the fragile hope of finding a new path forward. Secret endings and Easter eggs reward deep exploration and multiple playthroughs.

• D-Mail Mechanics — Craft and send D-Mails to specific points in the past, altering history in ways both subtle and profound. Each message costs something, and the consequences are never entirely predictable.

• Immersive Soundscape — An original ambient soundtrack and environmental audio design that captures the atmosphere of the Steins;Gate universe — the hum of CRT monitors, the static of a television displaying a dormant time machine, the silence between words when a character cannot bring themselves to speak.

• Character Relationship Webs — Your choices affect not only the plot but how characters perceive and interact with you. Trust, suspicion, affection, and fear shift dynamically based on your actions, unlocking or closing off narrative pathways.

Characters & Highlights

Okabe Rintaro — A broken scientist who has abandoned his Hououin Kyouma persona. He spends his days in a fog of grief and guilt, avoiding anything related to time travel. But when a mysterious organization begins hunting the remnants of the Future Gadget Lab, he is forced back into a world he swore to leave behind. Your choices determine whether he rediscovers his mad scientist bravado or descends further into despair.

Amadeus — A digital recreation of Kurisu Makise, created by the Viktor Chondria University research team. Amadeus possesses Kurisu's memories, her mannerisms, her intelligence — but she knows she is not real. She is aware of her own nature as an AI, and this existential horror colors every interaction. Can an artificial mind carry the soul of the person it was built from? And if so, can she be saved?

Mayuri Shiina — Mayuri is no longer the carefree girl who believes in Okabe no matter what. The weight of the Beta world line has changed her. She carries knowledge she cannot share, watches her friends fracture one by one, and makes choices of her own — some of which will haunt her forever. Her relationship with Okabe in this timeline is strained, fragile, and deeply moving.

Daru — Hashida Itaru has become a soldier in a war no one else can see. His hacking skills are now weapons. His humor is now armor. He works tirelessly to fight SERN's influence, but he is burning out. He needs Okabe's help — not the broken Okabe who gave up, but the one who used to believe he could change the future. Whether that man still exists is up to you.

The Beta Attractor Field — This world line exists in the shadow of two unavoidable futures: the SERN dystopia of 2036 and the Third World War that erupts in 2025. Every choice you make brings one future closer and pushes the other further away. The divergence meter is not a game mechanic — it is a countdown.

Who It's For

This interactive narrative is for anyone who has experienced Steins;Gate and wondered what happened in the world lines that Okabe abandoned. It is for fans of Steins;Gate Zero who want to immerse themselves in its emotional weight rather than simply observe it from a distance. It is for players who believe that visual novels and interactive fiction can deliver the same depth, complexity, and narrative sophistication as the finest literature or cinema. If you have ever sat through the ending of a story and asked yourself what came next, or what might have been if a single choice had gone differently, this experience is built for you. No familiarity with Steins;Gate Zero is required — this narrative stands on its own, though those who know the full saga will find deeper layers waiting for them.
