Following Fortnite's introduction of AI Darth Vader, Epic Games announces revolutionary tools enabling players to craft their own AI-driven NPCs within the battle royale universe.

Last month's debut of AI Darth Vader showcased groundbreaking capabilities - the digital Sith Lord can sing to players, dynamically join squads, deliver contextual responses, provide real-time gameplay summaries, and even issue strategic warnings.

James Earl Jones' legacy continues through this AI interpretation, utilizing Google's Gemini 2.0 Flash and ElevenLabs' Flash v2.5 technologies with full family approval. The legendary actor passed away in September 2024 at age 93.

The feature's launch saw immediate community creativity, with players coaxing Vader into uncharacteristic Dark Side behavior before Epic implemented safeguards.

At State of Unreal 2025, Epic demonstrated upcoming creator tools allowing personalized AI NPC development through UEFN's new Persona Device. Creators can customize voices, personalities, and interaction styles for unique in-game characters.

"We're democratizing the technology behind Darth Vader for our creator ecosystem," an Epic representative stated.

Major IP integrations are coming to UEFN, including Squid Game launching June 27, Avatar: The Last Airbender, and comprehensive Star Wars assets. LEGO functionality arrives June 17 alongside the innovative LEGO Bloom Tycoon template.

The event also showcased CD Projekt's breathtaking Witcher 4 Unreal Engine 5 technical demonstration.
