Toby Fox offers updates on Deltarune in celebration of Undertale’s 10th anniversary

Toby Fox’s Undertale was a bit of a cultural phenomenon when the game first launched all the way back in 2015. In celebration of its 10th anniversary, Fox not only took a look back at the past decade, but also forwards into the future – offering updates on the current status of Undertale’s in-development sequel Deltarune.

Releasing a newsletter to celebrate the game’s 10th anniversary, Undertale creator Toby Fox announced a number of events which will be taking place in honour of this major milestone. Alongside the likes of a dev-playthrough of Undertale and a Japan-exclusive concert, Fox offered an update on the current status of Deltarune.

As of now, Chapters 1-4 of the sequel have been released for all to enjoy, with Chapters 5-7 currently being worked on.

According to Toby Fox “The early parts of Chapter 5 are complete, but need polish in optional areas,” with “the last 40%-or-so of the game” said to be “in a rough first pass state” – with the final 10% in a “prototyping state.”

While the full blog post can be found HERE, Fox did offer fans a timeline of sorts for when to expect the full and complete version of Deltarune to be released, stating “Currently, we have one main deadline: I want to begin the translation by the end of 2025. After that point, gameplay changes will be acceptable, but large-scale text and story changes will be heavily frowned upon. Factoring the localization and testing… I don't think that the game will be released in the first half of 2026.”

With the very first chapter of Deltarune launching all the way back in 2018, it could very well be a decade before we get the final complete version of the game on our hands. That said, you can’t rush art, and so it will be exciting to experience the full story of Deltarune once it finally arrives “when it's done.”
