Unreal Engine 5.9 has received an early preview, and it’s causing a bit of controversy among developers. The latest iteration of the platform that tops our pick of the best game development programs is all about AI, and that includes its own development.
The UE 5.9 Preview is Epic Games’ first engine release built mainly via agentic workflows. A lot of the updates it introduces are also around AI-assisted workflows, including the use of Unreal MCP, Unreal Assistant and a new AI-driven content creation tool called Unreal Canvas.
The Unreal Engine 5.9 MegaJam Preview is here!
It’s the first Unreal Engine release built primarily with agentic workflows and opens up a few new Experimental features: check out Unreal MCP’s expanded toolsets, work with AI coding agents directly in Editor, explore AI-assisted content creation, and run your projects in a browser.
This isn’t your typical Unreal Engine Preview, but it’s ready just in time for the Epic MegaJam.
Invite your agents and start experimenting: https://t.co/5WpPJnT4PWNovember 9, 2026
