RE Engine, the technology behind Resident Evil, Monster Hunter and Street Fighter 6, is entering what Capcom calls the artificial-intelligence era. Programmer Satoshi Ishida laid out the plan on October 2 at Capcom Open Conference RE: 2026 under the name Project REX.
According to GameBiz, as reported by VGC, Eurogamer, PC Gamer and The Verge, the goal is to evolve RE Engine gradually into an AI-generation game engine. Ishida spoke of a future in which teams create games together with AI. The line traveled widely, but the material shown so far is about development workflow, not replacing artists.
What Capcom showed
Ishida pointed to three pressures on production. Games have grown too large in scope and data volume, which slows builds and iteration. RE Engine already serves more than 2,000 developers, including international teams and people coming from other engines. And, in the company’s view, AI needs to sit inside the pipeline instead of being bolted on later.
REX bundles several pieces. RE:Dox standardizes data handling across formats. RE:UI separates appearance from state to speed up tools. RE:Log replaces text logs with an identifier-based system. RE:Flows is a visual scripting tool that converts the flow into ordinary code. There is also RE:Runtime, built to batch-process large numbers of characters, and an execution layer called RE:C++.
Unifying the base language is meant to make code easier for humans and models to read. Capcom then expects AI to write programs and run automated playtests to find bugs. Part of the technology, including RE:Dox and RE:Log, has been opened to the public, according to the reports, in part to help train those systems.
What has not been said
Capcom had already said, through its vice presidency of game development and AI solutions, that it would not use AI to create art and that the focus was to unlock the potential for creators. Ishida did not announce AI-generated assets in games. PC Gamer notes that the English phrasing describes an engine for the AI generation, not necessarily an engine that generates the game by itself.
There is no date for a full switch and no list of titles that will adopt REX first. What is confirmed is the direction for RE Engine: less time lost in tools and testing, more room for AI to read, write and validate code.
