Remaking NetHack as a 3D Action RPG with Gemini 4 Carbon in Antigravity

A developer used Gemini 4 Carbon in Google's Antigravity platform to remake the 1987 roguelike NetHack as a modern 3D action RPG, porting it to web technology and wasm. The build relied on the /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 plan.
