STEINS;GATE RE:BOOT Octet of Shifting Space

STEINS;GATE Octet of Shifting Space is the early-purchase bonus adventure attached to STEINS;GATE RE:BOOT on Steam. Publisher materials describe it as an 80s PC-style STEINS;GATE adventure. It is charming side content, not a compressed remake of the reboot’s Phone Trigger campaign. This page separates entitlement rules, unlock timing, and buying mistakes.

What the bonus is

Octet presents a distinct retro presentation—think limited-color adventure framing rather than RE:BOOT’s full modern visual novel rebuild. Completing RE:BOOT is not gated behind Octet, and Octet will not teach you the reboot’s save discipline. Treat it as dessert after (or between) mainline sessions.

Campaign window (Steam)

Spike Chunsoft’s Steam campaign states that purchasing the Standard Edition or Digital Deluxe Edition during the early window grants Octet as a free bonus entitlement. Materials cite a window beginning with pre-orders and extending through approximately November 30, 2026 (confirm the exact timezone string on the Steam offer module). Buying outside the window may mean paying separately later—or missing a free grant entirely.

When Octet becomes playable

Even if entitlement appears on your account earlier, Octet’s playable release is listed for October 29, 2026 in Western bonus copy. That date aligns with the broader October console conversation, including the Western Xbox delay. Do not expect August Steam night to equal “Octet playable tonight.”

Deluxe versus Octet

Digital Deluxe typically adds a visual book, soundtrack, and 15th LIVE footage. Octet is a separate campaign entitlement. You can receive Octet on Standard during the window; Deluxe is not a requirement for the bonus game itself. Compare media extras on Edition Comparison and campaign text on Pre-order Bonuses.

Platform reality check

The free Octet grant is framed around Steam purchases in the Western campaign posts. Console editions may advertise different physical stickers, SteelBooks, or retailer extras instead. Xbox Western players waiting until October should not assume the Steam Octet offer automatically appears on their Xbox library. See Xbox Western Delay and Platforms.

How to avoid entitlement anxiety

1. Screenshot the Steam offer module showing Octet eligibility when you purchase.
2. Keep the email receipt and note whether you bought Standard or Deluxe.
3. Add October 29 to your calendar for Octet unlock—not only RE:BOOT console dates.
4. Run Pre-order Checklist the night before checkout.

Narrative priority

If time is scarce, finish RE:BOOT systems prep first: Getting Started, Phone Trigger, Save Strategy. Octet can wait in the library. Veterans who already know the classic story may nibble Octet between routes; newcomers should protect first-pass immersion.

Release Schedule, Reboot News, Official Resources, and the Tools Hub keep purchase utilities together. If a reseller lists “Octet codes” at suspicious prices, walk away—official campaign grants are storefront entitlements.

Octet is a love letter to older adventure presentation. Enjoy it as a bonus worldline snack, and keep RE:BOOT as the main laboratory experiment.

Receipt discipline

Store the Steam purchase email and the offer FAQ URL together. If Octet fails to appear after the playable date, support tickets move faster with timestamps than with vibes.

Replay value expectation

Expect a shorter, stylized adventure—not another thirty-hour Phone Trigger campaign. Schedule it as a weekend palate cleanser after a heavy RE:BOOT chapter, not as homework that blocks endings.

Side-content scheduling

Block a weekend after October 29 for Octet if you like retro adventures. Do not schedule it over your first RE:BOOT Saturday—protect the main experiment.
