Developer Shares NetHack 3D Remake Tutorial Using Gemini 4 Carbon
Start here
A developer published a step-by-step tutorial on remaking the 1987 roguelike NetHack as a modern 3D action RPG using Gemini 4 Carbon inside Google's Antigravity platform, porting the game to web technology and wasm. The build relied on Antigravity's /swarm feature, which spawns subagents with separate contexts to review each other's output, plus a Blender MCP server for 3D asset generation. Gemini 4 Carbon is available through the Google AI Ultra subscription plan. To let the agent access the model in a local environment, users must either set GEMINI_API_KEY in advance or install the Gemini API plugin from Antigravity's Marketplace. The tutorial notes that personal experimentation is generally free, but users should check the project's license before commercial use or publicly sharing results.
