a set of cross-play tools for developers. Epic Online Services now offers an overlay that can merge Steam and Epic Games friends lists and help players find their buds, send friend requests and hop into multiplayer sessions with cross-platform in-game invites.

Epic has broader ambitions for cross-play support beyond Steam. It’s working to support other PC launchers, as well as macOS and Linux. It will add cross-play tools for consoles and mobile to the SDK further down the line. Several of Epic’s own games — including Fortnite, Rocket League and Fall Guys: Ultimate Knockout — have full cross-play support.
