Get ready, gamers, because the wait for the next big DELTARUNE adventure is almost over! After years of development, Toby Fox's indie hit sequel to UNDERTALE is reaching the finish line. With a confirmed release date of June 5, 2025, it’s time to prepare for a chapter-packed RPG experience. And this applies to players except Xbox: the release will debut on PC, Mac, Nintendo Switch, Nintendo Switch 2, PlayStation 4, and PlayStation 5.

Such an intro would suit a completely new game if DELTARUNE were one...

But DELTARUNE is not exactly a new game.

Its first chapter was released back on October 31, 2018, and the second in September 2021. It’s being developed by the same legendary Toby Fox, the creator of Undertale. And yes, the game is a spiritual successor, but with a different story and a new approach to battles.

Several more chapters are planned, and the entire game will be released fully paid when finished. Toby Fox says he wants to release chapters 1–4 at once, with the rest arriving as updates, but without extra charges.

Thinking of 2025 as a stacked year for gaming? You’re not wrong. For proving check a full list of confirmed 2025 game releases. But for now, let’s dig into what makes DELTARUNE such a standout.

For those unfamiliar, DELTARUNE is the brainchild of Toby Fox, the same developer behind the critically acclaimed UNDERTALE. While the two games share familiar characters and a similar quirky charm, this is not a direct sequel. Instead, DELTARUNE exists in its own universe, a world with different rules, connections, and plenty of mysteries to uncover.

The game lets players step into the shoes of Kris, a human teenager who, along with their companions Susie (a hilariously tough monster) and Ralsei (a kindhearted prince), must seal portals called Dark Fountains to prevent chaos from consuming the world. Along the way, you’ll encounter strange characters, face off in exhilarating battles, and unravel a story that’s equal parts heartwarming and mind-boggling.

Still, DELTARUNE isn’t just about its story. Its gameplay elevates traditional RPG mechanics with a unique twist. You’ll find strategic turn-based combat spiced up with intense bullet-dodging sequences where split-second moves matter. The game draws inspiration from Touhou's bullet hell mechanics and classics like Chrono Trigger. Add to that its episodic release format, which encourages you to savor the story bit by bit, and you’ve got a recipe for something truly special.

Fun fact? Not only do characters like Sans and Toriel make a return, but the game also has just one ending this time. Yup, there’s no branching multiple-ending dilemmas here, though choices still matter in shaping how you experience this parallel world.

DELTARUNE delivers on its promise of being bigger, weirder, and more polished than its predecessor. Here’s what to expect when it drops in June 2025.

The combat system is a standout, blending traditional turn-based strategy with real-time reflexes. You’ll pick your moves from a menu of options like Fight, Magic, and Spare, while also navigating dodge-heavy bullet patterns. The Tension Points (TP) system adds another layer of depth, letting you use team-based spells and actions. Whether you’re sparing enemies or taking the more aggressive route, battles feel dynamic and rewarding.

The game’s structure is chapter-based, making it easy to revisit favorite moments or jump in wherever you left off. Upon release, Chapters 1 through 4 will be playable, with future chapters rolling out as free updates. This layout works perfectly for anyone who wants to fully absorb the story’s twists and turns at their own pace.

Another highlight is the artistry. Temmie Chang, known for her work on UNDERTALE, brings incredible life to the game’s world through expressive pixel animations. And yes, her in-game character even sports a snazzy new hat! The attention to detail adds a handcrafted vibe that’s both nostalgic and fresh. On the audio front, Toby Fox once again steals the show with a massive, meticulously crafted soundtrack. Every track—from the emotional ballads to the uptempo battle themes—is destined to become an earworm.

And for challenge-seekers? Hidden bosses are back and as devilishly hard as you’d expect. Prepare to sweat.

Ever since DELTARUNE Chapter 1 launched back in 2018 as a surprise free demo, it’s been clear this game had the potential to become another indie classic. Chapter 2, which arrived three years later, only stoked the flames further with more dynamic gameplay and richer story beats.

Fans on Reddit and gaming forums are busy dissecting trailers and patching together theories for how the plot will evolve over the next chapters. Across platforms like PC, Mac, PlayStation, and Nintendo Switch, the excitement feels infectious. Players new to the series are intrigued by the hype, while long-time UNDERTALE fans are ready to welcome yet another Toby Fox masterpiece into their collections.

That said, not every voice is completely confident. Some wonder whether the episodic structure will maintain its magic through Chapter 5 and beyond, or if waiting for updates might frustrate players. Still, there’s an overwhelming trust in Fox’s ability to deliver, given his track record and unshakable dedication to his craft.

If you’re a fan of UNDERTALE or enjoy games with quirky humor, emotional depth, and engaging combat, DELTARUNE is a no-brainer. Every aspect, from its handcrafted pixel art to its intricate worldbuilding, makes it clear that this game is built with passion, care, and an unwavering focus on the player experience.

Even if you’re new to Toby Fox’s work, DELTARUNE provides the perfect entry point. You don’t need UNDERTALE knowledge to appreciate it, and the chapter-based storytelling makes it digestible for casual players and RPG veterans alike.

In a nutshell, DELTARUNE is a game for anyone who loves creativity in gaming.

Don't miss this, everyone. June 2025 is just around the corner! Oh, and a bit about a price—DELTARUNE will cost $24.99 in North America.
