Deltarune Chapter 5 launches to nearly 300,000 concurrent players on Steam, Chapter 6 is coming in 2027

The long-awaited fifth chapter of Deltarune hit Steam like an asteroid yesterday, sending its concurrent player count skyrocketing to nearly 300,000—more than double its previous peak player count—and putting the game amidst the platform's top 10 best-selling games. Despite its age and somewhat irregular release schedule, interest in the game clearly remains high. And for those many of you who are interested in it, the good news is that more is on the way.

"The story is still continuing, and more chapters will be added for free over time," a brief FAQ on the Deltarune Steam page says. "We are aiming for a 2027 release! Meanwhile, we will be periodically releasing information on the development progress of the game."

Deltarune has had kind of an odd, shifting structure over the years. The first chapter was released for free in 2018, and then in 2021 the second chapter arrived, and despite expectations it was also free.

Creator Toby Fox, whose previous game Undertale was also a massive hit, warned that subsequent chapters would not be free. The plan at that point was to finish chapters 3, 4, and 5, and then release all five chapters as a paid game—but then that changed in 2025 when Fox put out Deltarune chapters 3 and 4, marking the game's "official" release, while work continued on chapter 5. Chapters 1 and 2 remain free, and anyone who purchases chapters 3 and 4 will get any and all subsequent chapters free.

Chapter 6 won't be the end of the Deltarune tale either: As noted by IGN, Fox said in a recent newsletter that work on chapter 6 is going so well, "it’s not unrealistic that some staff members may start working on Chapter 7 before the end of the year."
