Toby Fox has been a busy guy. During today’s Nintendo Switch 2 Direct, the small white dog dev showed the first full trailer for Deltarune Chapters 3 and 4, revealing that chapters 3 and 4 will launch alongside the Nintendo Switch 2 on June 5. It will also be available on all other platforms: PS5, Xbox Series X and S, and PC.

Deltarune’s first two chapters are mysterious little RPGs following a character named Kris through their adventures in a “Dark World” with their classmate Suzie and a prince named Ralsei. They borrow a number of characters and themes from Fox’s previous work, Undertale, but thus far it’s been unclear if there’s any relationship between the two stories. Trailers lately have been referring to it as a “parallel” story to Undertale.

In today’s trailer, we got our first-ever look at Chapters 3 and 4, though the look was cryptic as is Fox’s wont. There was a brief look at the Castle Town with all the characters we’ve met so far hanging out together (including Queen!), a new battle that looked like some sort of rock show with Guitar Hero-like controls, Suzie throwing Kris into what looks like a chapel with both characters slightly off-color, and a look at two new villains. One, for Chapter 3, appears to be a creepy smile in a static-y TV (recalling the tease at the end of Chapter 2), and the other, a bit less comprehensibly, seems to be a pile of…weird jellyfish? That Suzie and Kris are running from? No idea.

Deltarune has thus far been released chapter by chapter, with chapter 1 coming out on Halloween 2018, and Chapter 2 debuting in September of 2021. Both of the first chapters were free. The total number of chapters is still unknown, but the menu screen has previously seemed to hold room for seven total, meainng that two more may be on the way. The anticipation for these latest chapters has only grown in the last year, with Fox confirming last Halloween that 3 and 4 would “100% come out in 2025”. The Nintendo Switch 2 version will include all four chapters, including the two previously released.

Though we haven’t yet reviewed the beginnings of Deltarune, we gave Fox’s previous game, Undertale, a rare 10/10, calling it a “masterfully crafted experience.”
