Toby Fox announced that professional testers are currently familiarizing themselves with Deltarune's Chapter 5, with formal testing starting on April 1st. The quality assurance for the Japanese translation is expected to finish in April. Most of the development team is currently focused on fixing bugs and translation issues rather than developing Chapter 5. The testing phase will last an unspecified duration, requiring console approvals and additional preparations before release. The gap between the first and second chapters was three years, and the wait for the dual release of chapters three and four was nearly four years, but the timeline for Chapter 5's release is expected to be shorter. It is speculated that there may be seven chapters in total. The first two chapters are available for free on Steam.
