Agent-built Unreal city wows dev: downtown, marina, launch pad all generated overnight
chrisfirst · x · 2026-11-15
Developer chrisfirst showed what his AI agents cooked up overnight on an Unreal game: a downtown, central park, suburbs, a marina, an industrial port, a launch site on a pier, and two hills with winding roads — all built autonomously, with screenshots to prove it.
The project isn't done: it runs at 30 fps, the audio mix is unlistened, and bugs remain. But almost nothing was purchased — everything uses free Fab assets plus a few generated hero props. It's an #EpicMegaJam entry, and a striking demo of where agent-driven game development stands today.
