Capcom, the studio behind Resident Evil and Street Fighter, announced sweeping changes to its proprietary RE Engine during a technology conference held on October 2. During the event, titled Capcom Open Conference RE: 2026, programmer Satoshi Ishida delivered a presentation outlining the REX Project, an incremental improvement initiative designed to evolve the engine toward what Capcom describes as an “AI-generation game engine” for the next generation of development.
The announcement marks one of the most significant technical shifts in Capcom’s recent history. Rather than discarding the RE Engine and building a replacement from scratch, the company plans to layer improvements over time through the multi-step REX program. According to Ishida’s presentation, titled “The Outlook and Future of the REX Project, Further Evolving the RE Engine for the Next Generation,” the initiative addresses three core challenges facing modern game development: increasingly massive games that make simple processes time-consuming; larger teams that demand engines easier for everyone to use; and the growing necessity of integrating AI into development workflows.
Solving Modern Development Bottlenecks
As reported by Japanese news outlet GameBiz, Ishida identified the specific pain points driving Capcom’s decision. As games grow larger in scope, even routine tasks have become extraordinarily time-intensive. Simultaneously, studios are staffing up with more personnel who need accessible tools to remain productive. Finally, successfully weaving AI into development pipelines has emerged as an essential condition for streamlining future production.
The REX Project was created specifically to tackle these issues by improving the efficiency of game development, performance, tools, and quality assurance. Capcom concluded that gradual enhancement over time represents the best path toward evolving the RE Engine rather than abandoning it entirely. In a notable move, the company confirmed it will make at least some of these improvements open-source for the purpose of training AI systems.
“We will not implement assets generated by AI into our games. However, we plan to proactively use it as a contributing technology to improve the efficiency and productivity of the game development process. To this end, we are currently exploring ways to implement it in various areas, including graphics, sound and programming.”

A Future Where We Create Games Together With AI
GameBiz reported that REX unifies the entire RE Engine system under what it described as “the world’s most common programming language,” making the engine equal parts easier for humans to use and simpler for AI to understand. Capcom’s stated goal is to build a future where it “creates games together with AI.” In practice, this appears to mean leveraging artificial intelligence to accelerate and streamline certain processes rather than generating assets or artwork wholesale.
This approach aligns with Capcom’s established position on the technology. The company has historically been averse to using AI to create in-game assets but has consistently signaled willingness to deploy it as an optimization tool. This distinction proves central to understanding REX, which focuses on developer productivity rather than automated content creation.
A Pivotal Year for Capcom
The technical announcement arrives during a remarkably productive period for the company. This year alone, Capcom has delivered three critically acclaimed titles in Resident Evil Requiem, Pragmata, and Onimusha: Way of the Sword. The studio is also expanding into film with Zach Cregger’s Resident Movie adaptation and Legendary’s Street Fighter project, which is set to release in theaters on October 16, 2026.
The REX Project represents Capcom’s most concrete step yet toward its long-term vision of an AI-assisted development pipeline. As the studio continues refining the RE Engine across multiple improvement phases, developers and industry observers will be watching closely to see how far Capcom intends to push its partnership with artificial intelligence in shaping the games of tomorrow.
