Chapter 6
Deltarune Chapter 6 (subtitle unknown) is the upcoming sixth and penultimate Chapter of Deltarune,[2] set to release as a free update to the full game.[3] The development team have stated an intent for the Chapter to be released in 2027, although no specific date has been given yet.[1]
Chapter 6 will be immediately available to all existing owners of the paid version of Deltarune as a free update upon its release. It will also be available by default in all copies of the game bought after its release. Upon Chapter 5's release, the Steam page announced a 2027 projected release window.[1]
- During the fight with the Hammer of Justice in Chapter 4, he recounts that Lord of the Hammer's sixth installment was the last one written,[4] as "The story, it became so grand, so overwhelming" that "it swallowed up the author himself." It is likely that this is meant to parallel the events of Chapter 6.
- Susie is implied to invite Noelle to visit Castle Town and inform her of the stakes involved, per the ending of Chapter 5.[5]
- The Weird Route will likely skip over Chapter 6, as evidenced by the ending screen of Chapter 5's Weird Route.
- The vendor track Shop 3, which currently only plays for Pink's shop, is implied to play once again in this Chapter and/or Chapter 7, as Toby Fox described the song as being used for "most of the remaining shopkeepers in the game", in the Winter 2025 Newsletter.[6]
- Chapter 6's plot is implied to be darker than Chapter 5's, as Toby Fox described the latter as "one more fun adventure" before the sun "goes down completely". In the full description, the sun is used as a metaphor for the opposite of "dark clouds on the horizon" in Chapter 4.[7]
- Seam may use five Shadow Crystals for something "very, very, interesting".[8]
- This chapter is implied to not have certain recurring features that all appeared in each of the first five Chapters:
- Chapter 6 may lack a Shadow Crystal boss and Egg.[9][10][11]
- The Chapter might also lack an appearance from the Original Starwalker, due to his "Final Starwalker" transformation and dialogue in Chapter 5.
- When eating Chapter 5's moss after gaining the previous moss title, Kris's title changes to "Last Moss - A moss liker's final form", indicating there may be no moss to be consumed this chapter.
Most of the development team had begun working on Chapter 6 as of March 17, 2026.[12]
In the DELTARUNE Chapter 5 Release Date Announcement newsletter, released on June 9, 2026, Toby Fox announced that:[13]
- Cutscenes and NPC interactions are "making good progress".
- Overworld gameplay is mostly done aside from some rooms using the new gimmicks.
- Normal enemies and their bullet patterns are mostly complete.
- The final fight's bullet patterns are still being worked on.
Toby has stated that development is progressing smoothly as Chapter 6 is "easier to make than the others" and that therefore it is "not unrealistic" that some of the development team will start working on Chapter 7 before the end of 2026.[14]

That’s why, let’s not look there for now. Let’s turn around and watch the sun, before it goes down completely.
Let’s smile again.
Let’s have one more fun adventure, okay? - ↑
I, however, am aware of something interesting we can do with them. Something very, very, interesting.

This sounds crazy, but it’s not unrealistic that some staff members may start working on Chapter 7 before the end of the year.
