Bring Your NPCs to Life with NPC Builder for Unity!

Transform Your Game with Truly Interactive NPCs

Welcome to the future of game development. NPC Builder for Unity brings your NPCs to life like never before — smarter, more responsive, and deeply customizable. This is our first Unity SDK, fully aligned with the latest version of NPC Builder, and it’s ready to revolutionize how your players experience characters in your world.

Highlights:

• Intelligent NPC Interactions
