Deltarune Chapters 3 & 4 is Toby Fox’s latest project. Here is everything you need to know about the highly anticipated expansions’ release date and official start times.
Undertale launched in 2015. Toby Fox developed most of the game alone, including the programming, story, and collaborated with one other developer, Temmie Chang. Despite being such a small project, Undertale is widely considered one of the best games of all time, and Deltarune launched as a follow-up in 2018.
Deltarune Chapters 1 & 2 launched as a follow-up in 2018 and received similar high praise. Deltarune is not a direct sequel, but it features some of the characters and gameplay elements fans know and love. After years of waiting, the following two chapters are almost here.
Deltarune Chapters 3 & 4 Release Date

Deltarune Chapters 3 & 4 officially launch on June 5 for PlayStation 5, Xbox Series X|S, PC, and Nintendo Switch 2.
There is only one edition of the game, priced at $24.99. In addition to the two new chapters, the game also comes with the first two chapters. Upcoming chapters will be added as free updates.
You can also purchase the soundtrack on Steam for $14.99, and it contains over 150 songs. Every time a new chapter is added, you also get those songs.
To celebrate Detarune Chapters 3 & 4 being a launch title for the Nintendo Switch 2, a special room has been designed specifically for the simultaneous use of two controllers with mouse controls. Other versions of the game also feature a special room, but they will have a different control scheme.
