Games

There is no official game called “Undertale 2.” Toby Fox has never announced a direct numbered sequel to his 2015 game Undertale. What he did make instead is Deltarune, a spiritually connected but narratively separate game releasing in paid chapters, currently priced at $24.99 USD for Chapters 1-4 with Chapter 5 included as a free update. This guide explains the actual relationship between the two games and how to legally get Deltarune and the original Undertale today.

Does Undertale 2 Exist?

No. Undertale, released in 2015 by indie developer Toby Fox, has no direct, numbered sequel, and Toby Fox has never announced one under that or any similar title. Undertale’s story reached a genuine conclusion across its multiple endings, and Fox’s creative energy since 2015 has gone into a different, though thematically related, project: Deltarune.

Any site, video, or listing claiming to offer an “Undertale 2 download” is either referring to fan-made content mislabeled as an official sequel, confusing Undertale with Deltarune, or in the worst cases, attempting to distribute malware under a misleading, search-friendly title. It’s worth being cautious around any such claim, since no legitimate “Undertale 2” product exists to download from any storefront.

What Toby Fox Actually Made: Deltarune

How Deltarune Relates to Undertale, Explained

Deltarune shares many returning characters, art style, and musical themes with Undertale, and is explicitly intended by Toby Fox to be played after finishing Undertale first, but it takes place in an entirely separate continuity rather than continuing Undertale’s specific story or ending. Where Undertale followed a human child navigating the Underground and its monster inhabitants, Deltarune follows Kris, a resident of a normal surface town, who gets pulled into a parallel Dark World alongside classmates Susie and Ralsei.

Fox has described Deltarune as “a different story, for a different audience” than Undertale — meaning fans expecting a direct continuation of Undertale’s specific plot and characters’ fates should understand Deltarune is its own separate narrative, even while clearly sharing the same creative universe and tone.

Key Features of Deltarune

• A chapter-based release structure, with Chapters 1-5 currently available and more planned.
• Turn-based combat with the same bullet-hell dodging mechanics Undertale popularized.
• A parallel “Dark World” narrative separate from Undertale’s continuity.
• Returning fan-favorite characters alongside an entirely new main cast.
• An original soundtrack composed by Toby Fox, continuing his distinctive musical style.
• Chapters 1 and 2 were originally free; the full package from Chapter 3 onward is a paid purchase with all future chapters included as free updates.

Deltarune’s Release Structure and Pricing

• Chapters 1-2: Originally released for free in 2018 and 2021 respectively.
• Chapters 3-4: Released together in June 2025 as part of a $24.99 paid package.
• Chapter 5: Released June 24, 2026, included free for anyone who owns the paid package.
• Future chapters: Toby Fox has confirmed all upcoming chapters will be added as free updates for those who already own the game.

Pros and Cons of Waiting for “Undertale 2” vs. Playing Deltarune Now

Tips for New Players

• Play the original Undertale first — Deltarune is explicitly designed for players who’ve already finished it.
• Go in with an open mind about the new setting and characters rather than expecting a direct continuation.
• Experiment with both violent and non-violent approaches to encounters, since Deltarune keeps Undertale’s mercy-based combat options.
• Take note of small details and callbacks — Toby Fox’s writing rewards close attention across chapters.
• Check the official Deltarune and Undertale websites for legitimate news rather than relying on unofficial rumor sites.

Who Should — and Shouldn’t — Play Deltarune

Why the “Undertale 2” Search Confusion Persists

Search interest in “Undertale 2” has remained consistently high for years, largely because Undertale’s massive and dedicated fanbase naturally wants more content from Toby Fox, and many casual searchers aren’t aware that Deltarune — despite being a genuinely separate game with its own title — is effectively that continuation of Fox’s creative output. This gap between what fans are searching for and what the actual product is called has led to persistent confusion, and occasionally to bad-faith sites exploiting that confusion with misleading “Undertale 2” listings that don’t lead anywhere legitimate.

Toby Fox himself has been transparent about this distinction in interviews and official communications, consistently referring to Deltarune as its own separate project rather than a numbered sequel, even while acknowledging the games share a creative DNA that makes the confusion understandable.

How Deltarune’s Chapter Structure Works

Rather than releasing as one complete game, Deltarune has been built and released incrementally, with Toby Fox and his growing development team working on each chapter as a distinct unit before moving to the next. Chapters 1 and 2 were released for free in 2018 and 2021 respectively, establishing the game’s world and characters before the decision was made to package Chapters 3 onward as a paid release, with the understanding that anyone who buys in gets every future chapter at no additional cost.

As of this writing, Chapter 5 released in June 2026, with Chapter 6 in active development and targeted for a 2027 release, meaning the full scope of Deltarune’s story is still being written and released incrementally rather than existing as a single, complete game today.

Common Questions About Fan-Made “Undertale 2” Content

Because no official sequel exists, a number of fan projects, ROM hacks, and fangames have used “Undertale 2” or similar titles over the years, none of which are affiliated with or endorsed by Toby Fox. These fan projects vary enormously in quality and completeness, and none should be confused with, or searched for expecting, an official continuation of the series — treat any such fan content as clearly separate from Toby Fox’s actual work.

If you’re specifically interested in fan-made content inspired by Undertale, it’s worth searching for it by its actual project name rather than “Undertale 2,” both for clarity and to avoid confusingly named unofficial or unsafe downloads.
