Epic Games has announced a significant update for Fortnite, confirming that 36 of the game's existing characters—including staples like Agent Jones and The Imagined—will now feature consistent, AI-powered voices. These new audio capabilities are designed specifically for use within the Unreal Editor for Fortnite (UEFN), allowing creators to integrate these characters into their own custom islands.

Quick Facts

  • Feature Launch: The system exits its experimental phase and becomes available for published islands on July 30, 2026.
  • Technology: The voices are powered by Google's Gemini AI.
  • Voice Models: Performances were captured from independent professional actors who explicitly agreed to have their voices used for these models.
  • Scope: 36 characters are currently included, with plans to expand to other original Fortnite voice actors in the future.

How the AI Conversation System Works

The addition of these voices is an expansion of the broader "conversations system" Epic announced in April 2026. This system allows NPCs to engage in dynamic dialogue, reacting to player actions and specific verbal inputs. For example, if a player says "hello" to an NPC, the character is programmed to provide a relevant, spoken response.

Beyond simple greetings, the system enables characters to "remember" events that occurred during a specific game session. This allows for adaptive behavior, where NPCs can react to what a player has done or trigger new in-game events based on the flow of the conversation.

The Role of Voice Actors

The use of AI in this context has been a point of discussion for the industry. Regarding the development of these models, Epic stated in a blog post: "The actors agreed to have their performances used to develop voice models that create the spoken responses for these LLM-powered Fortnite characters."

Looking ahead, Epic notes that its next step is to engage with guilds and the specific voice actors who have previously provided work for Fortnite Battle Royale. The goal of these discussions is to explore opportunities to bring those original voices into the broader Fortnite ecosystem using similar technology.

Past Challenges with AI

Fortnite has previously experimented with AI implementation, most notably with the inclusion of an AI-powered Darth Vader. That instance resulted in players finding ways to manipulate the character into saying inappropriate content, which eventually necessitated a patch. As the platform transitions these new AI voices out of the experimental phase and into live, published environments, the focus remains on how these tools will function when placed in the hands of the wider creator community.
