Claude Opus 5 and Codex turned my rough idea into RIFTFALL, a full 3D retro FPS with 17,000 lines of code, 20 handcrafted boss arenas, multiple biomes, advanced enemies, cinematics, achievements, leaderboards, cloud saves, controller support and a playable Steam demo.
The game was built using Claude Opus 5, OpenAI Codex, GPT, GitHub, JavaScript, Three.js, WebGL, Web Audio, ElevenLabs, NW.js, Chromium and Steamworks.
