Undertale creator Toby Fox recently provided an update on the testing phase for Deltarune Chapters 3 and 4. Read on for details on console testing and what to expect.
Deltarune's Console Testing Progressing Smoothly
Save Transfers from Chapters 1 & 2

Toby Fox, via his Bluesky account, shared that console testing is underway. While much work remains, progress is positive. He noted fewer bugs but a significant amount of testing still needed, even for the PS5 version. Beyond bug fixes, the team is working on a crucial feature: transferring saves from the Chapters 1 and 2 demo to the full release. This functionality, recently made possible by new technology, is a key goal. "I hope it works!" Fox added.
With beta testing progressing well, a release date may be approaching. Fox confirmed a 2025 release for Chapters 3 and 4.
Introducing Tenna: A New Character Revealed

Amidst the development efforts, Fox shared a humorous anecdote. He showed family and friends a minigame he's developing, which they described as "a cry for help because your game is not out." While his family found this positive, a friend laughed for ten minutes straight.

This sparked speculation that the minigame might be for Chapter 5, given Fox's 2024 statement that Chapters 3 and 4 were content-complete. Deltarune is planned for seven chapters.
He further revealed, "Same friend who played Chapter 3 like over a year ago also told me ‘I miss Tenna’ and I was like ‘man that's something no one in the world has ever said huh’." Tenna, a previously unseen character first glimpsed during the Spamton Sweepstakes campaign (September 2022), is confirmed for Chapter 3.

Deltarune, the successor to Undertale, retains many of its predecessor's mechanics while introducing a new story and characters. Players will once again follow Kris, Susie, and Ralsei on a world-saving adventure.
