Toby Fox reveals that Deltarune Chapter 5 is a few months off, but development is going very well.

Toby Fox, the mastermind behind Undertale and Deltarune, has indicated that Chapter 5 of Deltarune likely won’t drop in the first half of 2026. Recent updates suggest that this timeline is becoming more realistic, as he shares that there’s still a significant amount of work ahead before the chapter’s release.

In a recent winter newsletter, Fox unveiled a new video showcasing Castle Town from the fifth chapter. However, it was his detailed update on Chapter 5 that really caught my attention. He enthusiastically reported, “Progress is going excellently! We have begun the localization process! We extracted the text from the game… 8-4, and I annotated all of the text with notes for the translator.” But that’s just the beginning.

He elaborated, “After localization reaches its final stages, we will begin testing with a professional testing team. We also need to examine how the game operates on consoles. We will start considering that in January.” Fox then provided his “realistic estimate” for the release of the next chapter: “If I had to give a realistic estimate, I believe that it will take several months to release the game from where we are now.”

With winter here, it’s time for another DELTARUNE NEWSLETTER! This edition is packed with exciting content, including concept art for Chapters 3 and 4. While the emails are being sent out, it may take some time for everyone to receive them.

Fox also made an interesting observation: “It feels crazy to say this even though only 6 months ago you guys only had Chapters 1 and 2, but in a few months, much of the team will probably already be focusing their attention on Chapter 6…” It seems that while Chapter 5 is a priority, the elusive Chapter 6 is already on the radar as well. He wrapped up the update with “a few more details,” as he put it.

“All the rooms in the game are more or less done, minus polish to the backgrounds. Almost all the scenes in the game are complete. A single digit amount of them need visual polish. Most of the battles in the game are done, except for a couple. These unfinished battles function from beginning to end, but need adjustments to their pacing and bullet patterns to be considered complete. The game contains hours of fun!”

Hours of fun, you say? It feels like we just got our hands on Chapters 3 and 4 along with the Nintendo Switch 2 content, but I’m definitely not complaining. Here’s hoping Chapter 5 arrives sooner rather than later. Fingers crossed!
