Why People Love Undertale

Games like Undertale land because every monster is a person. Chatforce is a tool where you describe a game in chat and AI agents build it, in 2D or 3D, single-player or multiplayer. Below are nine games like Undertale, then how to build your own. Combat is a menu, fight, act, item, mercy, and choosing mercy actually means something. Every named character has a theme song. Every dialog line has a typing-blip per voice.

The game watches what you do across the whole run and rewires itself accordingly. Pixel art, indie ambition, and a soundtrack iconic enough to chart on Billboard combine into a story that hits harder than its scope predicted. It is the cleanest example of how mechanics encode ethics.

Can You Build Something Like Undertale with AI?

Yes. Here is how, with Chatforce. The Top-Down Overworld engine handles the walking-around-towns part, and the Visual Novel / Management Sim engine handles the menu-driven combat and dialog. A top-down RPG guide can help shape the exploration side of that structure.

The coder fuses them into Undertale’s exact pattern: walk around, bump into an enemy, drop into a menu-driven combat with a real mercy option. You will not write Toby Fox’s script in a session, but a playable build with three towns, eight NPCs, a fight-or-spare encounter, and three endings is the right size for a Chatforce build.

What You’ll Need to Build It

  • Sprite Style

    Pixel art with personality. Each NPC needs an instantly readable silhouette. The artist keeps every dialog portrait and overworld sprite on-model across the whole game, so each NPC stays recognizable.

  • Music Style

    One leitmotif per named character. The sound engineer composes a unique theme for every NPC, plus a calm overworld theme and a tense combat variant.

  • Mechanics

    Tile-based overworld walking plus a menu-driven combat with fight/act/item/mercy. Choices write to save state and gate endings. The coder ties the engines together.

  • Level Design

    A small overworld with three towns, a few interiors, and a path between. The artist generates tile sets; the coder lays the rooms with NPC trigger points for dialog.

  • Characters

    Your hero plus eight or so named NPCs, each with a portrait, a sprite, a theme, and dialog. Per-character consistency keeps every NPC instantly recognizable.

  • UX Patterns

    Dialog boxes with portraits, a typing-blip per character voice, a four-option combat menu, an HP bar that reads as a heart. The coder has built it before.

How Chatforce Would Build It

  1. The Studio Director writes the cast

    The studio director scopes a small overworld with three towns, eight named NPCs, two combat encounters (one with a fight-or-spare branch), and three endings. The studio director picks the Top-Down Overworld engine for the world and the Visual Novel / Management Sim engine for dialog and combat menus.

  2. The Artist draws the friends

    The artist drafts the concept screenshot, your hero meeting their first NPC in a doorway, pixel art with charm and personality. Every NPC stays on-model for the rest of the game, so the cast feels like one consistent world.

  3. The Coder wires the dialogue

    The coder assembles the Top-Down Overworld scene with tile-based movement and the Visual Novel / Management Sim flow for combat encounters with a four-option menu (fight, act, item, mercy). Player choices write to save state and gate endings.

  4. The Sound Engineer scores the cast

    The sound engineer composes unique character themes so every named NPC gets their own motif, plus original sound effects for the iconic text-blip per character voice and the chimes for menu choices. Theme music does the heavy lifting.

Three Prompts to Try

  • Library spirits

    “A dialogue-driven story RPG where I am a librarian and the ‘monsters’ are book ghosts. Combat is a menu: read, listen, gift-bookmark, mercy. Pixel art with a soft pastel palette, lo-fi piano themes per ghost.”

  • Diner regulars

    “A story RPG set in a 24-hour diner. The encounters are regulars I serve through one long shift. Mercy is ‘listen, refill, comp the pie.’ Hand-drawn ink art, jazz-piano themes per customer.”

  • Forest spirits

    “A story RPG where I am a kid lost in a forest of spirits. Each encounter is a spirit with their own theme and grievance; mercy is ‘apologize, gift, sing along.’ Watercolor pixel art, choir-led themes.”

Frequently Asked Questions

Can Chatforce build an Undertale-style story RPG?

Yes. Chatforce combines the Top-Down Overworld engine (for walking around towns) with the Visual Novel / Management Sim engine (for dialog, menus, and the fight-or-spare combat flow). You will not match Toby Fox’s years of writing in a session, but a playable overworld with three towns, named NPCs, and a fight-or-spare encounter is the right size for a Chatforce build.

What’s the closest engine in Chatforce to Undertale?

Top-Down Overworld for the exploration plus Visual Novel / Management Sim for the dialog-heavy combat menus. The coder fuses the two into Undertale’s exact pattern: walk around, bump into an enemy, enter a menu-driven combat with mercy as a real option.

How long would it take?

A first playable build with one overworld town, three NPCs, two combats, and a fight-or-spare branch takes a single Chatforce session. Adding more towns, named NPCs, and multiple endings is the iterative second pass.

What art style options work for this?

Pixel art is Undertale’s signature, and the artist handles it natively. Hand-drawn ink, manga style, cute chibi-2D, or modern flat all also work. Character consistency matters more than style, and the artist keeps your whole cast on-model.

Can I build it in 3D instead?

Yes, but pick it up front. You choose 2D or 3D when you create the game. A 3D build gets generated 3D models, real-time lighting, and a camera you direct in chat. A dialog-first RPG spends most of its screen time in portraits and text boxes, so 2D carries the mood more cheaply here.

Can a story RPG be multiplayer?

Yes. Chatforce builds real-time multiplayer for up to 8 players, and everyone joins from the same shared link in their browser. Story games are usually solo, so the honest answer is that multiplayer is available but rarely the right tool: if you want it, a two-player encounter where each player takes half the mercy/fight menu is the version that fits.

Can I share the finished game?

Yes. Every Chatforce game lives at a shareable URL. Send a link, and players play in their browser.

Will players need to install anything?

No. Your game runs in any modern browser, on a desktop or a phone. Builds ship with on-screen touch controls, so the link you share plays on mobile too, and there is no installer for you or your players.
