We’ll receive the first draft of the Japanese translation of Chapter 5 next week!
Meanwhile, we’ve been polishing the game and doing some preliminary internal bugtesting on PC. Heavy bugtesting across every console will happen when the Japanese translation is done.

With localization reaching its final stages, there is a tangible sense of progress. Nevertheless, as is typical with Toby Fox updates, the Deltarune community has reacted with its signature brand of chaotic enthusiasm. The comment sections are already teeming with humorous edits of his post and premature proclamations that the chapter will drop “tomorrow.”

Die-hard fans have flooded the thread with frantic demands and playful threats to “explode” if they don’t get their hands on Chapter 5 immediately. However, the most charming reaction addressed the technical side of development: “Please remember to pet the bugs as you politely ask them to leave,” one user suggested. “It makes the process much more pleasant.” It is a surprisingly wholesome sentiment amidst the usual internet frenzy.

Everyone is holding out hope that Deltarune Chapter 5 will arrive sooner than initially projected. It’s wise to keep a close watch on Fox’s social feeds for sudden announcements—his updates often arrive without warning, and the resulting community discourse is always an entertaining read.

Visionary dev Toby Fox has shared a glimpse of new Chapter 5 dialogue, sending the RPG’s dedicated fanbase into a fever pitch as they wait for the next installment later this year.
