Dominik Kundel demonstrated the versatility of the Codex app server by having theCodex AI agent autonomously integrate itself into the game DOOM.
- Codex modified the DOOM engine and game maps to create a functional, in-game terminal. This allows users to interact with the AI agent directly within the game world to perform coding or game-related tasks.
- The setup uses an Electron app with a fork of `doom-wasm`. The agent patched the game data (Freedoom) and implemented a custom C file (`codex_terminal.c`) so the terminal renders natively within the engine rather than as a simple UI overlay.
- Codex handled the entire end-to-end process—coding, testing, and verification—with minimal human intervention. It even used Playwright to "play" the game itself to verify that textures and logos rendered correctly from different angles.
The project serves as a "demo-driven" proof of concept to show that the Codex app server can be embedded into any software environment or workflow, from IDEs to video games.
