Exciting Update: Toby Fox Confirms Completion of Deltarune Chapters 3 and 4 in 2025

In early 2025, the renowned developer Toby Fox, recognized for his contributions to Undertale and Deltarune, shared exciting news regarding the progress of Chapters 3 and 4 of Deltarune. This announcement comes after a prolonged period of silence, revealing that both chapters are set to be completed this year and will be accessible on personal computers and consoles. Fox has been more engaged with his dedicated fanbase and has resumed activity on Bluesky to keep them informed about his development endeavors.

At this stage, Chapters 3 and 4 of Deltarune are undergoing testing on various consoles. Numerous bugs are still present in these versions, and work has yet to commence on the PS5 edition. Nonetheless, the timeline appears to remain intact for this year, with developments for Chapter 5 now progressing "more smoothly" due to recent team additions.

Deltarune first debuted in October 2018 for platforms including PC, Mac, PS4, and Nintendo Switch. While Fox has yet to make any confirmations regarding additional versions apart from the PS5, there is speculation about the potential for Deltarune to be launched for the Nintendo Switch 2 as a native version rather than simply backward compatible with the original Switch.
