Start with the developer’s free newsletter
Use the official DELTARUNE / UNDERTALE mailing list for periodic announcements. It is the simplest native way to follow development without repeatedly checking search results. You do not need a monitoring app to receive the developer’s general updates.
For the source behind the 2027 answer, read Toby Fox’s Summer 2026 newsletter. The wording expresses confidence in a target year, not a promised month or day. The official game FAQ, marked updated June 24, 2026, still describes Chapter 6 as in development and directs readers to the website or newsletter.
Keep three questions separate: what year is being targeted, when a precise launch announcement arrives, and whether your installed game actually offers the chapter. A newsletter can answer the first before either of the others becomes true. Search snippets, fan countdowns and an old trailer can blur those stages.
What is confirmed, and what remains unknown?
| Question | Official evidence checked November 2 | Practical meaning |
|---|---|---|
| Is there a target year? | The summer newsletter targets 2027. | A useful planning window, without a particular month or day. |
| Is Chapter 6 bundled with Chapter 7? | The same newsletter says Chapter 6 would release by itself. | Do not turn a Chapter 6 update into a combined Chapter 6–7 launch date. |
| Is Chapter 6 available now? | The homepage advertises Chapter 5 and Chapters 1–5; the FAQ describes Chapter 6 as unfinished. | Current availability and future development have separate evidence. |
| Will future chapters cost extra? | The FAQ says future chapters will be free updates when ready. | Check that you own the full game; the demo is a separate product. |
| Is there an exact platform rollout time? | The checked Chapter 6 sources give no specific date or time. | Do not copy Chapter 5’s old launch clock into a Chapter 6 calendar event. |

The table deliberately keeps unknown fields empty of guesses. “2027” does not mean January 1, the anniversary, a console showcase or the end of the year. A plausible fan estimate can still be useful discussion, but it is not interchangeable with a date announced by the developer.
Read development progress without calculating a deadline
The summer update describes ongoing work on Chapter 6’s structure and remaining production tasks. That is evidence about the development stage. It does not provide enough information to calculate the remaining weeks, and the newsletter itself allows for restructuring.
The earlier Chapter 5 release-date announcement is a useful comparison of announcement formats. It gave a particular calendar day, time and worldwide platform statement for Chapter 5. Its separate Chapter 6 progress section was not another release-date announcement. Those statements should not be merged just because they appear on one page.
This distinction matters if you encounter a screenshot stripped of its heading or a video whose title only says “release date.” Check which chapter the source actually names. Then check whether the statement concerns development progress, a target window, an announcement or a release that has already happened.
Our Silksong: Sea of Sorrow release guide applies the same distinction to a different project. It cannot supply Deltarune’s schedule; each developer’s own announcement has to establish that.
Check your copy before preparing for the update
The official FAQ lists the full game on PC, Mac, Nintendo Switch, Nintendo Switch 2, PlayStation 4 and PlayStation 5. It also distinguishes the Chapter 1&2 demo from the full game. That matters when someone expects a future full-game chapter to appear inside an older demo installation.
Check the product name in your library and the relevant store listing. You can identify the copy you own now without guessing the size, download time or installation procedure of an unreleased Chapter 6 update. The sources checked here do not establish those future details.
When an exact launch notice arrives, record the chapter number, date, time zone and platform wording together. If a notice gives a simultaneous worldwide time, convert that announced time to your local zone. Until that exists for Chapter 6, publishing a conversion table would give false precision.
Use the official trailer as context, not a Chapter 6 date
The official homepage currently links a Chapter 5 announcement trailer. It helps identify which chapter the current campaign promotes. It is historical context for the existing game, not a Chapter 6 trailer or evidence of a new launch day. Avoid it if you want to see no footage from the released chapters.
Video linked from the official DELTARUNE website. It concerns Chapter 5; its release information must not be reused for Chapter 6.
Watch for a narrower visible announcement on your Mac
The newsletter remains the first choice for general news. If you specifically want to know when the official homepage changes to an exact Chapter 6 launch notice, PageDog can check a selected visible area locally on your Mac for that condition. The current Chapter 5 promotion provides a clear baseline to verify before creating the watch.
An example condition is: “This official page visibly announces an exact release date for DELTARUNE Chapter 6.” Include the chapter label and announcement text in the selection. Reload first and confirm the same area remains visible. A change from one Chapter 5 promotion to another should not satisfy that condition.
The Mac must remain available for scheduled checks. Relevant captured evidence goes to the configured AI service when AI checks are used. PageDog does not predict the date, inspect your game library, follow every newsletter link or guarantee that a future announcement appears inside your selected area. If the homepage layout changes, revise the selection and verify the original notice yourself.
For a broader explanation of choosing an observable signal, see our website change monitoring guide. Here, the signal is a named chapter and explicit date, rather than every edit to the site.
The answer to keep until a new announcement
Use 2027 as the developer’s current target, keep the exact date unconfirmed, and subscribe to the native newsletter if you want general updates. Treat Chapter 6 and Chapter 7 separately. When the official source becomes more precise, update your plans from that announcement rather than from a countdown built on speculation.
