Capcom details REX and wants RE Engine AI as the engine’s next step

Capcom wants to take RE Engine, the technology behind Resident Evil 7 and dozens of later games, toward what programmer Satoshi Ishida called an AI-generation engine. The comments came at Capcom Open Conference RE:2026 on October 2, in a session on the REX project.

According to GameBiz, as reported by VGC, REX does not replace RE Engine. The plan is to add new systems in stages to an engine used since 2017 and now present in more than 27 company titles. Ishida cited three pressures: games that have grown too large, more than 2,000 people using the tools, and the need to fit AI into production.

What REX promises

The package includes named pieces. RE:Dox standardizes data handling. RE:UI aims to make internal tools lighter by separating appearance and state and cutting freezes. RE:Log replaces text logs with IDs, which also makes automatic translation easier for teams outside Japan. RE:Flows converts visual flows into a more common programming language. RE:Runtime groups instances and translates code into an internal dialect called RE:C++.

AI sits inside that design. Ishida said unifying the base on a widely used language makes the code more readable for models. In the horizon he described, AI could generate programs and run tests to find bugs. Capcom has also opened parts of RE:Dox and RE:Log, with the stated aim of helping that training.

The line that sums up the goal, according to GameBiz, is a future in which Capcom “creates games together with AI.” That is an engineering direction presented at a conference, not an announcement of a model-generated game.

Art stays out, in the official line

The counterpoint already existed inside the company. Shinichi Inoue, vice president of the game development platform and AI solutions, had said Capcom sees the technology “not for creating art, but for unleashing the potential of creators.” Ishida’s newer comments do not revoke that line, but they widen AI’s role to code, testing and tools.

RE Engine debuted in Resident Evil 7 and became a commercial argument for Capcom: an in-house engine shared across Monster Hunter, Street Fighter 6, Dragon’s Dogma 2 and the Resident Evil series. REX is an attempt to keep that asset from aging in the race for faster production. What is not confirmed is a timeline, which game will be first to use these pieces, and how far automatic code generation leaves the lab.
