Capcom Reworks Its Game Engine for AI Development

Capcom revealed its REX strategy at the Capcom Open Conference RE:2026 in Tokyo on October 2. Programmer Satoshi Ishida said the RE Engine, now more than eight years old, will evolve step by step to let humans and AI collaborate on game development. This includes using the engine's built-in AI features to understand and generate code, run tests, and catch bugs.

It is worth noting that this is a long-term strategy, not a quick fix. Capcom itself calls it a "phased project." When I picture agents working with my code, here is roughly what comes to mind: an agent reads the code, runs tests, finds bugs, and I check the result by hand before release. That approach could work well for large studios with their own in-house engines. But it will not necessarily cut costs, and it will not necessarily remove the need for a QA department (quality assurance, the team that tests games for bugs). The statement does not give any specific figures on potential cost savings.
