The in-house RE Engine at Capcom is undergoing a major transformation under the company’s newly introduced REX Project, with the goal of turning it into an “AI-generation game engine.”
Capcom’s Roadmap for AI-Powered RE Engine
During the “Capcom Open Conference RE:2026” on October 2nd, Satoshi Ishida, a programmer at Capcom, provided insight into the technical strategies that will update the RE Engine—the foundation behind nearly 30 titles since its initial use in Resident Evil 7 (2017). Ishida laid out several approaches designed to overcome the increasing complexities involved in building modern games.
REX Project Facing Modern Gaming Hurdles
The REX Project, according to Ishida, aims to tackle three core problems: the rising data size and project scope in games today, an increased demand for multilingual and accessibility support for their team of more than 2,000 developers worldwide, and a desire to infuse artificial intelligence into every part of the development workflow. Rather than viewing AI integration as a patch or add-on, Capcom wants AI to drive and reshape the game creation process from its foundation.
The overhaul will introduce a suite of new core components, including:
- RE:Dox—standardizes data processing among various formats
- RE:UI—improves development tools by separating appearance from internal logic, making UI development more efficient
- RE:Log—switches text-based logging to an ID-based system, strengthening data monitoring and management
- RE:Flows—offers a visual scripting interface that auto-translates developer flows into standardized code, streamlining both iteration and prototyping
- RE:Runtime—builds a reworked engine core focusing on batch processing for animation and efficient control of numerous characters
- RE:C++—delivers a refined execution layer for greater performance
Artificial Intelligence and Capcom’s Creative Pledge
Ishida elaborated that AI will be pervasive in all stages of making a game—assisting with code generation, conducting automated test runs for bug discovery, and providing real-time development aid. Ultimately, Capcom envisions game projects where “teams create games together with AI,” ushering in innovative workflows while carefully maintaining the creative contribution of people. Some elements of this technology have already been made open source, fostering a wider use of AI across the gaming industry through collaboration and training.
Capcom’s June update to investors noted that generative AI was being used to speed up routine development tasks. This allows developers to focus more on the creative aspects, with Capcom stating that the “fundamental artistic elements” in game design will remain the work of humans.
Monster Hunter Wilds Switch 2 Edition Launch Plans
On a separate note, Capcom announced that the Switch 2 version of Monster Hunter Wilds—which will have all free DLC including new monsters—has a scheduled release date of 4th December. This edition will also include local co-op, broadening the game’s multiplayer features.
By driving the REX Project forward, Capcom is modernizing its development pipeline, integrating powerful AI tools with human ingenuity to address the ever-evolving needs of today’s gaming landscape, while upholding the creative importance of its team members.
