Developer builds a 3D action game with 33 Claude Code agents

On October 5, 2026, the Chinese developer site Juejin published a report about a developer who built a 3D action game from scratch using Claude Code. According to the account, the developer supplied only a single written requirement and no assets of any kind. Claude Code then dispatched 33 agents, which generated every model, texture and sound effect in code. The result described in the report is a browser-based 3D action puzzle game that can be played through to completion.

The report also says it includes a playable online demo, a breakdown of the multi-agent workflow, and a record of the problems the developer ran into along the way.

That is the extent of what can be checked in the available material. The key details are the date of publication, the outlet, an unnamed developer, Claude Code as the tool, the figure of 33 agents, and a browser-based 3D action puzzle game whose assets were produced by code rather than sourced externally. The claims come from the developer's own description as relayed by Juejin. No other source in the material independently verifies them, and there is no third-party assessment of the game's quality or of how well the workflow performed. Whether anyone has reproduced the result, and whether further details have since been disclosed, is not covered by this report. Readers should treat the specifics as a single-account claim rather than a confirmed benchmark.
