Epic Games revealed a preview of Unreal Engine 6 during the State of Unreal show on May 17, 2026 [1].

The announcement signals a shift in game development toward artificial intelligence and massive simulations. By integrating large language models into developer workflows, Epic Games aims to reduce the technical friction of creating complex digital environments.

The reveal took place at UNREAL FEST 2026, held at the McCormick Place in Chicago [1]. The company showcased a suite of new capabilities, including improved scalability and support for larger simulations. A primary focus of the presentation was the integration of AI-assisted workflows, which allow developers to use LLM-based tools to streamline the production process [2].

To demonstrate these features, Epic Games partnered with Psyonix, the developer of Rocket League. A specialized demo was presented during the Rocket League Championship Series Paris Major in France [2]. This transition is particularly significant for the title, as Rocket League had been running on Unreal Engine 3 for 11 years [3].

The move to Unreal Engine 6 represents a jump across three major versions of the software. This leap allows the game to utilize modern rendering and simulation techniques that were unavailable in the legacy engine. The demo highlighted how the new engine handles the physics and scale required for the competitive title while leveraging the latest AI tools [2].

Epic Games used the Chicago and Paris events to position the engine as a foundation for the next generation of interactive media. The company said the updated engine is designed to handle the increasing demands of high-fidelity gaming and real-time simulation [2].

The jump from Unreal Engine 3 to 6 for a live title like Rocket League underscores the widening gap between legacy game tech and modern AI-driven engines. By embedding LLM-assisted workflows and high-scale simulation support, Epic Games is attempting to standardize AI as a core utility for developers rather than a peripheral feature, potentially lowering the barrier for creating massive, complex open worlds.
