Overview
- Satoshi Ishida outlined the REX project at Capcom Open Conference RE:2026 on October 2 as a multi‑year effort to retrofit the company’s RE Engine so AI and machine learning can read and act on its code and data.
- REX bundles named systems such as RE:Dox for standardized data, RE:UI for tool interfaces, RE:Flows for visual scripting, RE:Runtime for batch runtime work, RE:Log for compact telemetry, and a shared RE:C++ foundation to make the codebase machine‑readable.
- Capcom plans to enable AI-assisted code generation and autonomous playtesting that uses screen and audio input to find bugs, aiming to reduce manual QA workload and speed iteration on large, complex builds.
- The company will open‑source parts of the tooling, including RE:Dox and RE:Log, to help train AI and encourage broader integration while keeping most engine internals proprietary.
- Capcom reiterated that it will not ship AI‑generated game assets and that REX is an incremental evolution of RE Engine, a change that will reshape developer workflows, hiring needs, and how studios use logs and data for tooling.
