Narrative Engine - Dialogue & Story System

Narrative Engine is a complete narrative tool for Unity that helps you build interactive dialogues with branching choices - plus saving and rollback to return to previous decisions.

Create clean, game-ready dialogue UI for both PC and mobile, drive scene/background changes directly from the dialogue flow, and ship story interactions faster with a demo scene included.
Perfect for indie teams and commercial projects that need narrative features without overcomplicated setup.


KMA Dialogue System - Core Capabilities

Visual Dialogue Builder (Nodes & Branches)
Build dialogues as a clear node-based flow: lines, choices, transitions, and progression logic - organized and easy to maintain.

Branching Choices
Choice buttons appear only when the story requires them, keeping the UI clean and focused on decisions.

Dialogue Checkpoints, Saving & Rollback
Set up checkpoints, saving, and rollback behavior directly inside the dialogue flow - ideal for “your choices matter” scenarios and replayable story moments.

PC + Mobile UI Layouts
Included layouts for PC and mobile:
dialogue window size adapts to text length;
speaker nameplates and portraits appear based on who is currently speaking.


Scene / Background Switching from Dialogue
Trigger scene or background changes directly from dialogue nodes to keep narrative moments dynamic and visually clear.

Demo Scene Included
A complete demo scene that showcases all core mechanics of the asset.


Best Fit Genres

KMA Dialogue System shines in games where story, choices, and character-driven delivery matter - the kind of dialogue experience players recognize from many popular titles:

RPG / Action RPG - NPC conversations and dialogue-driven progression in the spirit of Mass Effect, The Witcher 3, Baldur’s Gate 3;


Adventure / Story-driven games - cinematic dialogue scenes and narrative pacing similar to Life is Strange, The Walking Dead (Telltale), Oxenfree;


Visual Novel / Interactive Fiction - choice moments with controlled story progression, as seen in Steins;Gate, Doki Doki Literature Club!, Phoenix Wright: Ace Attorney;


Detective / Mystery - interrogation-style conversations and clue-driven dialogue paths like Pentiment, L.A. Noire, Ace Attorney, Disco Elysium;


Survival / Horror - narrative events and decision pressure with dialogue beats like Until Dawn, The Quarry, The Dark Pictures Anthology;


Strategy / City-builder - advisor/event dialogues and story modules in the tone of Frostpunk, This War of Mine;


Roguelite / Roguelike - hub conversations and repeatable narrative beats similar to Hades and Cult of the Lamb;


Casual / Narrative (PC + mobile) - short-session dialogue-first experiences in the style of Choices: Stories You Play, Episode, Romance Club;


Educational / Serious games - scenario-based dialogues and decision-driven training simulations.



Why Choose KMA Dialogue System?

Because it’s more than a dialogue box - it’s a practical narrative-building workflow with the essentials: branching, checkpoints, saving, and rollback, backed by a demo that shows it instantly. Less boilerplate, more storytelling.
