- Epic is expanding licensed content in UEFN with Squid Game assets arriving June 27, a LEGO Brick Editor on June 17 and plans for Star Wars and Avatar: The Last Airbender integrations.
- The Epic Developer Assistant, now in beta, offers AI-driven coding support for creators writing in the Verse language on the Epic Developer Community site.
