Overview
- Epic introduced an Experimental “conversations” tool in Unreal Editor for Fortnite that creators can test but cannot publish to live islands.
- The system uses Google’s Gemini 3.1 Flash Lite to transcribe speech and generate replies and uses ElevenLabs to voice the characters.
- Creators define a persona with short prompts and the NPC can talk in real time, remember actions within a session, and trigger in-game events.
- Epic says voice models and response times are not final, it is covering model costs during testing, and there is no timeline for a beta that would allow publishing.
- Epic updated developer rules to ban medical or mental-health advice, romantic companion roles, and attempts to bypass content controls, and it says it will not store player audio.
