Unity games made with AI

Unity is a 2D and 3D game engine and editor from Unity Technologies, with builds for more than 25 platforms, the web among them. Game logic is written in C#. As of September 2026, Unity Personal is free for individuals and small organizations with under $200K in revenue and funds raised in the last 12 months.

An agent can write the C# scripts as text, and Unity can also save scenes in a YAML format that tools can generate and parse. Unity's own MCP server, part of its AI tools beta, lets Claude Code, Codex, Cursor and other agents inspect scenes, read the console and trigger editor actions. It needs Unity 6, a project linked to Unity Cloud, and a Unity AI trial or plan.

Web builds use WebAssembly with WebGL or WebGPU. The server has to send Content-Encoding headers for gzip or Brotli files, or the build embeds a decompression fallback with a bigger, less efficient loader.
