Inside Deltarune Chapter 5 — What’s Finished and What Still Needs Work

[cryptobro]

A fresh development update reveals that Deltarune Chapter 5 is deeper into production than many fans may have expected. According to Toby Fox, nearly all environments are built, with only background touch-ups remaining. Story scenes are also close to final quality, needing minimal refinement before release.

Only a handful of battles are still being adjusted, and Fox confirmed they are already fully functional. The focus now is on fine-tuning difficulty, timing, and the signature bullet-hell feel that defines the series.

Localization work has already begun, and once completed, the chapter will move into professional testing — a major milestone that puts Chapter 5 firmly into the late-stage development phase.
