Deltarune Dark World Walkthrough: Story Steps, Battles, Puzzles & Checklists
Want to explore Deltarune’s Dark World and keep your progress organized? This guide-style walkthrough is built to take you through the story steps that matter—covering key character moments, battles, and puzzle solutions as you go—so you always know what to do next.
Checklists
Right now, Deltarune Chapters 1 through 4 are available to play, with each chapter delivering hours of content plus plenty of hidden finds. After you finish a chapter, you can move on to the next one—or jump back to an earlier save file and continue from there.
Below are chapter-focused walkthrough sections, along with dedicated key item guidance and boss help designed to get you the most out of the experience. If you want to hunt down secrets or make sure you’re not missing important interactions, this is the easiest way to structure your playthrough.
Chapter 1 – The Beginning
Chapter 1 is crafted as a strong entry point, introducing the story’s core premise and dropping the protagonist (plus an unlikely companion) into a brand-new, mysterious world.
While you play through this chapter, keep an eye out for references to Undertale. There are plenty of nods to the earlier game, and they show up throughout the chapter.
Chapter 2 – A Cyber’s World
Chapter 2 brings Susie and Kris back into the Dark World, but this time you’ll face a fresh roster of enemies. Expect new puzzles and hidden treasures to dig up as you push forward.
If it’s been a while since you last played and you want a quick refresher, use the character guide to get back up to speed before continuing.
Chapter 3 – Late Night
In Chapter 3, the heroes are pulled into a strange, flashy gameshow setting. Along the way, you’ll meet new characters, work through puzzles, and take on boss fights that match the chapter’s bizarre tone.
The secret boss in this third chapter is especially memorable. You’ll run into it regardless, but the real difference is whether you manage to survive the encounter.
Chapter 4 – Prophecy
The night after a sleepover at the Dreemurr residence, Kris and Susie set out on a mission with a specific goal: uncovering the codes needed to open Hometown’s mysterious shelter at the edge of town. That quest takes you through Holiday Manor and into another stretch of the Dark World—one filled with echoes of Deltarune’s “Prophecy.”
Chapter 5 – Festival Day
A new day arrives in Hometown, bringing the Festival that Kris, Susie, and Noelle are set to attend. Before long, things go off-script when a new Dark World emerges—one that puts Kris’s adoptive father at his flower shop directly in danger.
Up Next: Chapter 1 – The Beginning
If you’re starting from scratch or revisiting, begin with Chapter 1 to get the story context and pacing down before moving into the later worlds.
