Capcom aims to evolve RE Engine into an 'AI-generation' game engine

At Capcom Open Conference RE:2026 in Tokyo, programmer Satoshi Ishida said the company's REX upgrades will push its RE Engine toward what he called an "AI-generation game engine," with tools that could someday help write code and catch bugs. Capcom still says it will not put AI-generated assets into finished games.

What happened

At Capcom Open Conference RE:2026 at Ariake Convention Hall, programmer Satoshi Ishida outlined the REX project (short for RE neXt Engine), GameBiz reported. Capcom's site lists the REX talk for Oct. 2. The company first announced REX in 2023 and is adding pieces over time rather than replacing the engine from scratch, Notebookcheck said.

Why it matters

RE Engine has powered Capcom hits since Resident Evil 7 in 2017 — more than 27 titles, with more than 2,000 Capcom developers using it, the conference reports said. Making tools AI-readable is Capcom's bet that big games stay shippable as teams and codebases grow.

What’s next

The Tokyo event wrapped with student sessions on Oct. 3; an Osaka leg follows Oct. 17–18, Capcom's site says. Watch for any ship date on REX AI helpers, and whether Capcom publishes more open components for training.

More context

Capcom says it wants its in-house RE Engine to become what one of its programmers called an "AI-generation game engine" — meaning tools built for the AI era, not a factory for AI art. The pitch came Friday at the company's own tech conference in Tokyo.

What REX adds: Ishida described components such as RE:Dox (common data rules), RE:UI (lighter tool interfaces), RE:Flows (gameplay ideas turned into standard code), RE:Runtime (efficient large crowds of characters), and RE:Log (central searchable logs), according to GameBiz and Notebookcheck. Capcom has already posted some of that work, including RE:Dox and RE:Log, online so AI systems can learn from it — not so RE Engine itself becomes a public engine.

The AI goal: Because REX standardizes on a widely used programming language, Ishida said, code should be easier for AI to read. Longer term, Capcom wants AI that can understand programs, help write them, and run test play to spot bugs, the reports said. Those are stated goals, not features Capcom has shipped, and no timeline was given.

Limits Capcom has set: In a March 2026 shareholder Q&A, Capcom said it "will not implement assets generated by AI into our games" but plans to use AI to raise efficiency in graphics, sound, and programming, IGN and Polygon noted. Shinichi Inoue, Capcom's VP of game development platform and AI solutions, has said the company sees AI "not for creating art, but for unleashing the potential of creators," Video Games Chronicle reported.

Pushback: Polygon called Ishida's remarks "red flags" for people who do not want AI in game development, while noting he was not describing tools that make art or other game assets. The Verge said the comments seem to leave the door open to wider AI use. Capcom's stated policy still rules out AI-made assets in its games.
