Epic to build cross-game voice chat into Unreal Engine 6 for third-party developers

Epic Games said Epic Parties' voice and avatar systems will be integrated directly into Unreal Engine 6, currently in development, with the tools offered to third-party developers. Epic Parties launched in Fortnite on 2026-09-03, with Rocket League to follow the next year. Epic CEO Tim Sweeney framed the cross-game social link as a solution for new multiplayer games struggling to attract players reluctant to leave established friend groups.
