Capcom unveils REX plan to gradually turn the RE Engine into an AI-generation game engine

At its Capcom Open Conference RE: 2026 on October 2, Capcom announced the REX project, a multi-step effort to improve the RE Engine with the long-term goal of turning it into an AI-generation game engine. Programmer Satoshi Ishida cited three development problems, including the time cost of large games, the need for an engine that is easy for a growing staff to use, and integrating AI into development workflows. REX unifies the RE Engine under a common programming language, with some improvements open-sourced for AI training; Capcom said at a March 2026 shareholders meeting that it will not put AI-generated assets into its games but will use AI to improve development efficiency.
