Evaluation

DELTARUNE launched on June 4, 2025 with Chapters 1–4 (Chapters 1 and 2 are free; Chapters 3 and 4 are paid). Chapter 5 released on June 24, 2026, following a release date announcement tied to a Nintendo Direct presentation on June 9, 2026. The store description's FAQ section directly addresses the game's future: it confirms that Chapter 5 is not the final chapter, that additional chapters will be added as free updates over time, and that Chapter 6 is targeting a 2027 release, with the developer planning to periodically share progress updates in the meantime. This is reinforced by the developer's own words in the Chapter 5 launch post on June 24, 2026: "we'll get back to working on the next chapters!" The July 22, 2026 patch notes further state that after one final patch, the team would "resume fully concentrating our development resources on Chapter 6 and 7." The July 31, 2026 patch notes — the most recent developer communication — confirm this transition has happened: "We will now return to focusing on developing Chapter 6." Chapters 6 and 7 are explicitly confirmed as in development, with a 2027 target for Chapter 6.

Evidence

Final Chapter 5 patch released; notes state 'We will now return to focusing on developing Chapter 6. We have no current plans for another patch unless any additional issues arise.'
