Dialogue System for Unity

The powerful, top-rated dialogue system used in Disco Elysium, 1000xRESIST, Citizen Sleeper, Eternights, Lake, Suzerain, Peglin, Jenny LeClue, and many many more, the Dialogue System for Unity makes it easy to add interactive dialogue and quests to your game. It's a complete, robust solution including a visual node-based editor, dialogue UIs, cutscenes, quest logs, save/load, and more. The core is a lean, efficient conversation system. A large collection of included, optional add-ons make it quick and easy to drop conversations into your project and integrate them with other assets. No scripting required.
