Undertale and Deltarune creator Toby Fox previously said he doesn't think the latter game's Chapter 5 "will be released in the first half of 2026" – but that doesn't mean it's not well underway, as the developer reveals translations are going smoothly.

We don't know when exactly Chapter 5 will arrive, with Fox having said in December that it's sadly still "several months" away, and Chapters 3 and 4 having released in the middle of last year – but thankfully, it sounds like progress is chugging along smoothly on the next part of the beloved Undertale follow-up. In a recent online post, the dev explains that his team is working on tidying up the Japanese translation of Chapter 5 currently.

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.

Hopefully, the translation will be complete soon, then. It does seem like it's on a good track, anyway, with the cleaning up of translations happening in the background and whatnot – but, as one might expect, the community isn't exactly being normal about the update from Fox… if you know, you know. There are the much-needed edited screenshots of his post among the comments, of course, reading "gay balls" and "Chapter 5 tomorrow."

We've also got folks demanding "DELTARUNE TOMORROWWWWWW" and other stans shouting, "TOBY, I NEED CHAPTER 5 RIGHT NOW, OR I WILL EXPLODE!" My favorite reply, though, has to be the one about bugs. "Please make sure to pet the bugs as you politely ask them to leave," it reads. "It makes them feel better." Believe it or not, it's one of the, uh, more normal responses, too – plus, it's cute.

Fingers crossed that Deltarune Chapter 5 will be here sooner rather than later. I'd recommend keeping an eye on Fox's social media accounts for any future updates, as he tends to just post them out of the blue (and do always browse the comments for extra fun).
