Overview
- Capcom outlined the REX plan at its Capcom Open Conference RE:2026, confirming on October 2 that it will incrementally evolve its RE Engine to let AI read, generate and assist with code and workflows.
- REX bundles named subsystems — RE:Dox for standardized data, RE:UI for development interfaces, RE:Flows for visual scripting, RE:Runtime for batch runtime work, RE:Log for compact telemetry, and a shared RE:C++ foundation — to create predictable formats that AI tools can use.
- Capcom will open-source select components, including RE:Dox and RE:Log, so outside systems can train on consistent data and logs while keeping most engine parts proprietary.
- The company said it will use AI for productivity and QA, pursuing autonomous playtesting that can observe screen and audio and automated code assistance, but it reaffirmed it will not ship AI‑generated game assets.
- Capcom frames REX as an incremental, early-stage program to scale known automation work across 2,000+ internal developers and formalize prior experimental QA systems, a move that could speed iteration but will require new oversight and validation of AI output.
