Undertale creator Toby Fox has provided an update on the testing phase for Deltarune Chapters 3 and 4. Read on for details about 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 significant work remains, progress is positive. He noted, "Still console testing. There are fewer bugs, but there's a lot to go through. (Haven't even tested PS5 yet)." Beyond bug fixes, the team is focusing on implementing save file transfers from the Chapters 1 and 2 demo to the full release of Chapters 3 and 4 on consoles. This feature, enabled by recently acquired technology, is a key goal: "I hope it works!"

This positive beta testing suggests a release may be imminent. Fox previously confirmed a 2025 release window for Deltarune Chapters 3 and 4.

Introducing Tenna: A New Character Revealed

Amidst the development efforts, Fox shared a humorous anecdote: "I showed my family and friends a minigame I've been working on for DR (Deltarune) and they all described it as ‘a cry for help because your game is not out’," he posted. While his family found it positive, a friend's reaction was less kind.

This minigame's existence sparked speculation that it might be intended for Chapter 5, given Fox's 2024 statement that Chapters 3 and 4 were content-complete. Deltarune is planned as a seven-chapter series.

Further fueling anticipation, Fox mentioned, "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 in September 2022, is confirmed for Chapter 3.

Deltarune, the spiritual successor to Undertale, retains many familiar mechanics while introducing a new narrative and characters. Players will continue the adventure alongside Kris, Susie, and Ralsei on their world-saving quest.
