Quick overview

Deltarune is a free role-playing game from Toby Fox, the creator of Undertale. It shares Undertale’s quirky humor, memorable soundtrack, and emotional beats, but it takes place in a separate world with a fresh storyline. The first two chapters are available at no cost, and additional chapters have been announced as paid content.

Origins and its relationship to Undertale

Toby Fox built a devoted following with Undertale thanks to its branching narratives and distinctive tone. Deltarune channels much of that same creative energy while intentionally avoiding a direct sequel or prequel relationship. Although a few familiar faces make cameo appearances, Deltarune introduces new characters and plotlines — more of a creative reinterpretation than a continuation.

Setting and story premise

The game borrows nostalgic, 8-bit-style presentation and retro-inspired music, yet combines those throwback visuals with modern writing and references. The basic setup echoes Undertale’s premise: a seemingly ordinary character becomes trapped in an underground world filled with puzzles, strange creatures, and moral choices. From there, Deltarune forges its own narrative path and tone.

Main characters

  • Kris — the mostly silent protagonist whose choices drive the story.
  • Ralsei — a caring, gentle companion who provides guidance.
  • Susie — a tough, unpredictable ally with a volatile personality.
  • Lancer — a mischievous character who adds comic relief and surprising depth.

Their relationships and differing motivations are central to the game’s emotional and narrative momentum.

Gameplay, tone, and progression

Deltarune preserves the series’ preference for nonviolent resolutions and emotionally charged encounters, while expanding both mechanical and narrative complexity over time. Combat blends classic RPG elements with options that emphasize mercy and negotiation rather than pure aggression. The developer has released the first two chapters for free; subsequent chapters will be offered as paid installments that continue the story.

Release plan and scope

The creator has indicated the complete saga will span multiple chapters. Two chapters are available now, and more are planned for future release as paid content. Each new chapter is intended to advance the plot significantly and introduce additional mechanics and story beats.

Accessibility and age suitability

Deltarune is generally approachable for younger players who can read and follow dialogue choices. The tone and mechanics are family-friendly in spirit, though some themes and emotional moments may be better suited for older children or teens depending on parental judgment.

Do you need to play Undertale first?

Playing Undertale is not required to enjoy Deltarune. The game stands on its own narratively and can be experienced independently, though Undertale veterans may notice layered references that add extra meaning for longtime fans.
