Capcom's REX project aims to turn RE Engine into an 'AI-generation game engine' for 'a future where we create games together with AI'
At the Capcom Open Conference RE:2026 on Oct 2, 2026, programmer Satoshi Ishida presented REX, a multi-stage plan to evolve Capcom's RE Engine (Resident Evil, Monster Hunter) into an "AI-generation game engine". AI would be built into development workflows, with the goal of "a future where we create games together with AI". Capcom has previously said it will not put AI-generated assets in its games.
Key facts
- Talk: 'The Outlook and Future of the REX Project, Further Evolving the RE Engine for the Next Generation' by Satoshi Ishida, Capcom Open Conference RE:2026 (Oct 2)
- Problems named: game scale makes simple tasks slow, bigger teams need easier tools, and AI integration is becoming key to efficiency
- Approach: evolve the existing engine incrementally rather than rebuild. Unify it under a common, widely used programming language for 'readability and comprehension for AI', so AI can write code and run playtests to find bugs (secondary reports)
- Quote (IGN's translation, via The Verge): a 'future where we create games together with AI'
- Capcom's stated position: no AI-generated assets in shipped games. AI is for development efficiency (The Verge)
What happened
In a technical talk on the future of RE Engine, Capcom described REX, a gradual overhaul meant to make the engine and its tooling usable by AI systems. That includes AI-written code and automated playtesting.
Why it matters
A top Japanese publisher is publicly committing its flagship engine roadmap to AI-assisted development while ruling out AI-generated assets. This reflects how big studios are handling the backlash: AI in the pipeline, not on screen. Details beyond The Verge come from secondary gaming outlets summarizing IGN's translation of the Japanese talk.
