Capcom Targets AI-Driven Overhaul of Its RE Engine

Core Announcement at RE:2026 Conference
On October 2, Capcom programmer Satoshi Ishida presented the “REX Project” at the company’s Capcom Open Conference RE:2026. He described the initiative as an effort to evolve the in-house RE Engine—the technology behind titles such as *Resident Evil 7* and roughly 30 other Capcom games—into an “AI-generation game engine.” The plan is presented as a multi-year overhaul that will embed artificial-intelligence capabilities directly into the development pipeline.
Why the Upgrade Is Needed
Ishida identified three pressures driving the REX Project. First, modern games have expanded in scope and data volume, causing build and iteration times to lengthen. Second, the RE Engine is now used by over 2,000 developers worldwide, creating a need for better multilingual and accessibility support. Third, current AI tools are added as after-thoughts rather than being integrated from the start. These challenges, he argued, hinder efficient production of large-scale titles.
Components of the REX Project
The REX Project bundles several new subsystems:
- RE:Dox – standardises data processing across formats.
- RE:UI – separates visual appearance from state to speed up tool development.
- RE:Log – replaces text-based logging with an ID-based system.
- RE:Flows – a visual-scripting environment that automatically converts to conventional code.
- RE:Runtime – a reworked core built around batch processing for massive character counts.
- RE:C++ – an optimised execution layer for the runtime.
Together, these modules aim to let AI understand and generate code, run automated test plays, and assist developers throughout production.
Official Stance on AI-Generated Content
Capcom has repeatedly clarified that AI will be used to improve development efficiency, not to create in-game assets. A later shareholders’ Q&A reiterated that AI-generated content will not appear in Capcom games.
Anticipated Impact on Development
If successful, the REX Project could shorten iteration cycles, reduce manual debugging, and enable larger, more complex scenes without proportionally increasing development time. By embedding AI into the engine’s core, Capcom hopes to maintain its rapid release schedule for legacy franchises while keeping pace with industry peers such as Epic Games, which have also integrated AI tools into their own engines.
