AI Product Lab Notes

AI agents do the implementation, people set the direction. These are the prototypes that came out of that workflow, and the notes from making them.

Building an MMORPG Map with AI: Five Days on One Forest

StatusPlayable · In development

A PvP sandbox MMORPG inspired by Shadowbane, with an Unreal Engine 5.8 client and an authoritative C# server, and all the code and levels done by AI agents. Taking the first full map, Northwood, as the example, this post covers the problems we hit building maps with AI and how we solved them: a four-step workflow, a map toolkit built around "edit the files and regenerate", and the traps along the way — cliffs that were too regular, ground that looked different from the ground you walked on, more than two thousand shafts in the map, and fire that vanished from the screenshots.

TBA Dev Log #1: From a Headless Simulation to a Wasteland Squad That Moves

StatusPlayable prototype · In development

A post-apocalyptic idle RPG that lives in your taskbar, built in Godot 4 with GDScript, code written by an AI agent from the command line. This entry records the first two weeks end to end: combat math and the economy loop were proven with no graphics at all, then a pixel-art presentation layer went on top. Along the way we shelved a home-grown layered character rig and threw out AI-generated fake pixel art.
