Developer Michael Luan has successfully created a browser-based 3D real-time strategy game Starfall using the Claude Opus 5 language model in multi-agent mode. The cost of generating the project was $632.65 in the complete absence of a preliminary design document or a list of resources. According to the disclosed technical data, the process required 68.6 thousand input and 4.6 million output tokens, as well as large-scale cache usage. The resulting product functions in a WebGL 2-enabled browser, while all visual elements, including ship hulls, textures, and celestial bodies, are generated by software code in real time without using ready-made graphical images.

The architecture of the game is based on procedural generation: ship hulls are formed by extrusion of specified sections, followed by the addition of detail within a set polygon limit. The surfaces are covered with a triplanar texture at three scales, tied to the radius of the object, which ensures visual consistency between two-kilometer carriers and small interceptors. The gameplay includes thirteen ship classes, a fleet management system in the style of the classic Homeworld game, as well as an economic layer with resource extraction and artificial intelligence of the enemy. The simulation operates at a fixed frequency of 60 Hertz, using a pool of entities and spatial hashing, while rendering is separated from logic and optimized through instantiation and substitution of distant objects with billboards.

The project pays special attention to automated testing: the repository contains specialized scripts for headless browser verification, calculating expressions on a live stage, and analyzing screenshot histograms. Most of the corrections in the code were detected by these tools, rather than by manual analysis. The game is distributed under the MIT open source license on the GitHub platform and is based on three technologies.js, Vite, and TypeScript. The creator positions the project as an independent homage to the classic 1999 strategy, emphasizing the complete absence of borrowed graphics, sound or trademarks of the original, despite the presence of minor game flaws characteristic of quickly generated content.
