Capcom to Evolve RE Engine into AI-Powered Game Engine
The Japanese gaming giant plans to transform its in-house engine into an 'AI-generation game engine' as part of the REX Project, aiming to improve development efficiency and integrate AI into the game development pipeline with new systems like RE:Dox and RE:Flows
Capcom has announced plans to evolve its RE Engine into an 'AI-generation game engine' as part of the REX Project. The project aims to create an engine where AI can understand and generate code, run automated test plays, and support development directly.
The RE Engine has been in development since 2014 and made its debut in Resident Evil 7 in 2017. It has been used in over 30 Capcom titles and is currently used by over 2,000 developers, including international staff and people coming from other engines.
The REX Project is driven by three challenges: large game scope and data volume, need for better multilingual and accessibility support, and the need to integrate AI into the development pipeline. To address these challenges, Capcom plans to bundle new systems into the REX Project, including RE:Dox, RE:UI, RE:Log, RE:Flows, and RE:Runtime.
## What's Changing The new systems aim to improve development efficiency and integrate AI into the game development pipeline. For example, RE:Dox standardises data processing across formats, while RE:UI speeds up development tools by separating appearance from state. RE:Flows, a visual scripting tool, automatically converts to standard code, and RE:Runtime is a reworked runtime core built around batch processing for large numbers of characters.
## Why it Matters The evolution of the RE Engine into an AI-generation game engine has significant implications for the gaming industry. By integrating AI into the development pipeline, Capcom aims to improve development efficiency, reduce bugs, and create a more collaborative development process. The use of AI in game development could also lead to new and innovative gameplay experiences.
Capcom has already open-sourced some of the underlying technology to help with AI training. The company announced its plans at the 'Capcom Open Conference RE:2026' event on October 2nd. With the REX Project, Capcom is taking a significant step towards creating a future where teams 'create games together with AI'
