Epic Games Confirms Generative AI Across Fortnite and Unreal Engine 6
Epic Games has confirmed it is using generative AI across its work, from the online game Fortnite to Unreal Engine 6, the next version of the software many studios use to build games. Generative AI means systems that produce new code, text or images from written instructions.
Marcus Wassmer, Epic's executive vice president of development, said the company uses AI to develop code and features for Unreal Engine. Eurogamer reported his comments on 28 October 2026. He said almost all development happening right now runs in development streams, the separate lines of work attached to Fortnite, the Unreal Editor for Fortnite (UEFN) and Unreal Engine 6.
Wassmer also confirmed that Epic is "vibe-coding" its Unreal Engine work. The term describes a way of building software by describing the result to an AI tool and steering its output, rather than typing each line by hand. In practice, he said, engineers no longer write the bulk of the code. They guide the tools toward the design they want.
Wassmer said Epic is more worried about the risks of moving too slowly on AI than about scepticism towards it. He said a halfway approach to AI in development is not viable for the company.
The shift is not new. In October 2026, 80.lv reported that Epic had told developers "No More Hand-Written Code" as part of an "AI-First" production model. Epic had also said earlier that it vibe-coded its new Epic Games Launcher, the store app used to download and play its games, to run slightly faster than Steam, the rival PC storefront run by Valve.
For players, the change is mostly behind the scenes. The statements describe how Epic's teams work, not a new feature in any game. Nothing in the coverage gives a release date or a list of tools that will carry the new approach to players.
What stands out is the scale of the stated change. Epic is describing a studio where the core job of writing code has moved toward directing software. Wassmer's comments give no figures on how many roles are affected, and Epic has not said how the approach will shape the timing of future releases.
Developers using Unreal Engine will be watching how the tools change under them. Epic makes its engine available to outside studios, so decisions made in the company's own development streams can reach other teams' work. The company has not said how outside users will be affected, or when.
