Steins;Gate: Octet of Shifting Space — The 8-Bit Sequel Localized

What it is: An English localization of a previously Japan-only title originally released for Windows XP/Vista/7 in 2011. It is a non-canon, retro-styled text-adventure sequel set after the events of Steins;Gate. Previously known in fan circles as "Variant Space Octet" .

Platforms: Nintendo Switch 2, Nintendo Switch, PlayStation 5, and Steam .

Release date & pricing: Not yet announced. Spike Chunsoft stated that details on how to obtain the game will be shared at a later date .

Bundle information: In Japan, Octet is offered as a first-run bonus for physical copies of Steins;Gate Re:Boot. The Western distribution model — whether it will be sold standalone, included as a pre-order bonus, or handled differently — is still being finalized .

Localization team: Translators Andrew Hodgson and H. Anthony Israel, who worked on the original Steins;Gate localization and the upcoming Re:Boot localization, are handling the English script .

What makes it unique: Octet is deliberately built to feel like a PC adventure game from the 1980s. It uses screen-drawing visuals, classic 8-color RGB and green monochrome graphics modes, and authentic FM synthesis / PSG sound chip music composed by Takeshi Abo . Instead of modern visual-novel choice menus, gameplay relies on text parser commands — you type commands like "GO NORTH" or "EXAMINE PC" as in classic 1980s text adventures . It supports both software keyboards and USB keyboards, and this marks its first-ever release on game consoles and Steam .

What Remains Unclear

• Octet pricing and standalone availability: Spike Chunsoft's official line is that details are "coming later." It is not confirmed whether Western players will be able to purchase Octet separately at launch, or if it will remain a physical pre-order / first-print bonus tied to Re:Boot .
• Re:Boot Digital Deluxe pricing: No price was given for the deluxe edition in any of the panel's press materials .
• Octet Western release date: No date has been set, only a window ("details TBA") .
