Sublustrum Release Date: Q1 2027 & the 2026 Playtest

When is the full Sublustrum remake coming out?

The current Steam store lists Q1 2027. That means the first quarter of 2027, a window spanning January through March rather than a confirmed launch day. The product is marked coming soon.

Older announcements and search snippets can still refer to a 2026 release plan. For current timing, prefer the live store listing. We have not established when the store field changed, so this page does not invent a delay-announcement date or the reason for the change.

Why can people play it in October 2026?

The public playtest is a separate Chapter One build. Its announced testing window is October 12–25, 2026. Playing that slice does not mean the completed campaign has been released. Playtest access covers enrollment and scope; getting started covers preparation.

Who is making the remake?

Steam currently names Brickworks Games as developer and HypeTrain Digital as publisher. The October 12 official announcement also describes their partnership. The original game’s studio history is separate from those current store credits; see original versus remake.

How can I check whether this changed?

Check the release field on app 4151300 and its official news. If a specific day replaces the quarter, record the source and update the verification date. A full-release walkthrough should also be checked against the released build before reusing playtest steps.
