Epic Games and Unity revealed an unexpected collaboration at Unite 2025 in Barcelona, Spain, marking a significant shift in the gaming industry landscape. Epic CEO Tim Sweeney joined Unity president Matthew Bromberg onstage to outline plans for cross-platform cooperation between their competing game engine technologies.
The partnership will enable Unreal Engine developers to access Unity's newly developed in-app purchase SDK for managing transactions across multiple platforms. Sweeney emphasized that the timing coincides with court-mandated changes forcing Google and Apple to loosen their mobile ecosystem restrictions following Epic's legal challenges.
A major component involves integrating Unity-built games into the Fortnite platform, which serves over 100 million monthly active users and maintains 500 million registered accounts. Independent developers already generate hundreds of millions annually from Fortnite content, with third-party creations accounting for 40 percent of total playtime. Unity developers will gain access to Fortnite's discovery system through networking technology, enabling cross-engine connectivity, allowing their games to participate in what Sweeney described as an evolving open metaverse economy.
