DELTARUNE

What Is DELTARUNE?

DELTARUNE is the spiritual successor and narrative parallel to the cult-classic UNDERTALE. Rather than continuing that story directly, DELTARUNE invites players into a familiar yet entirely new world—one where familiar faces return in unexpected roles and surprising new allies and enemies emerge. Set in a realm teetering between light and darkness, you’ll embark on a fantastical journey filled with heart-pounding turn-based combat, quirky dialogue, and moments that will tug at your emotions when you least expect it.

From the very beginning, you’ll take control of Kris, a seemingly ordinary student who stumbles into the Dark World alongside classmates Susie and Ralsei. Together, you form a mismatched trio with a common goal: to restore balance to the kingdom and return home safely. But nothing in DELTARUNE is ever quite what it seems.

A Cast You’ll Never Forget

Part of what makes DELTARUNE so magical is its unforgettable characters. Whether you're revisiting fan-favorite personalities from UNDERTALE or meeting new, lovable oddballs like Lancer and Queen, every interaction sparkles with Toby Fox’s signature wit and emotional depth. Dialogue choices matter—not just for laughs, but for shaping your relationships and the world around you.

Battles With a Twist

Combat in DELTARUNE brings a fresh twist to classic turn-based RPGs. Dodge enemy attacks in real time during bullet-hell segments, strategize your party’s moves, and decide whether to fight or show mercy. You can talk your way out of battles, spare enemies, or go full offensive—it’s entirely up to you. Your choices influence more than just outcomes—they shape your experience.

A Living, Evolving Experience

At launch, DELTARUNE features Chapters 1 through 4, giving players a substantial dive into its twisted fairytale world. And the best part? Future chapters will be available as free updates, ensuring your journey continues long after you start.

A Parallel Universe Worth Exploring

Fans of UNDERTALE will delight in the subtle (and sometimes not-so-subtle) parallels between the two games. But make no mistake: DELTARUNE stands firmly on its own as a rich, emotionally complex adventure. It’s not just a sequel—it’s a mirror, a riddle, and a celebration of everything that made UNDERTALE special, now bigger, bolder, and even weirder.
