Overview
- Capcom revealed the REX project at its Capcom Open Conference RE:2026 on Oct. 2 as a multi‑year plan to evolve the RE Engine so AI systems can read and interact with engine code and data.
- REX bundles six core systems—RE:Dox, RE:UI, RE:Runtime, RE:Flows, RE:Log, and RE:C++—that standardize data formats, tooling, logging, runtime and visual scripting to make the engine consistent for humans and machines.
- Capcom has already open‑sourced RE:Dox and RE:Log to help train AI and encourage interoperability while keeping other components under internal development.
- A central REX goal is autonomous QA: Capcom is building AI that can assess a build through screen and audio and run automated playtests to find bugs and reduce manual tester workload.
- Capcom stresses REX is for productivity and QA, not for replacing human creative assets, and it has publicly stated it will not ship AI‑generated in‑game art; the change could speed development across the company’s roughly 30 RE Engine titles and affect how studios train and deploy AI tools.
