Deltarune Chapter 5 was released on June 24, 2026, as a free update for existing players, setting a new Steam concurrent player record of nearly 291,000—more than double the previous peak of 133,920 players [1, 2, 3]. Toby Fox, the game’s creator, said, "Nope! The story is still continuing, and more Chapters will be added for free over time" [1].

Development of Chapter 6 has already begun and is progressing smoothly, with a planned release in 2027, Fox confirmed: "We are aiming for a 2027 release! Meanwhile, we will be periodically releasing information on the development progress of the game" [1]. Some staff members may also start working on Chapter 7 before the end of 2026, which Fox described as "not unrealistic" despite sounding "crazy" [2, 3].

Deltarune has an episodic structure likely spanning seven chapters, according to the chapter select screen and developer statements [1]. The first two chapters were released for free, while chapters 3 and 4 were sold as a paid package that includes subsequent chapters free of charge [3]. Chapter 5’s launch demonstrated growing popularity for the series with a record breaking concurrent player count on Steam [2, 3].

The game’s Steam page notes there will be "only 1 ending...?" for Deltarune, hinting at a singular narrative outcome despite the episodic format [1].

The timeline of releases began with Chapter 1 in 2018, Chapter 2 in 2021, chapters 3 and 4 in 2025, and Chapter 5 in June 2026 [1, 3]. Chapter 6 is scheduled for 2027, with potential early work on Chapter 7 before the year’s end [2, 3].
