Games · From the Field
He asked Claude to build Fallout in New York. Five days later, he had a browser game.
An ambitious fan project demonstrated agent-driven development, then went offline after its creator reported a legal demand.

THE TAKEAWAY
CHRIS FIRST’s experiment shows how much one person can attempt with development agents—and what happens when that ambition depends on someone else’s franchise.
WHAT HAPPENED
The request was specific: recreate Fallout in New York, including its familiar interface, systems and fictional brands.
The creator describes directing Claude and specialist agents through a roughly five-day build. His making-of follows the construction of ruined Manhattan, with visual and audio elements generated through code rather than downloaded asset files.
WHY IT MATTERS
The project later disappeared. CHRIS FIRST posted what he described as a ZeniMax cease-and-desist and took it offline. That notice has not been independently authenticated in the reporting reviewed here.
HOW THE PROJECT WAS BUILT
Direction
The creator set the goal and guided the work.
Agents
Claude and specialists built and checked parts of the game.
Code-generated assets
The creator says visuals and sounds were produced programmatically.
One person attempted a recognizable game world through an intensive conversation with development agents.
VEYR ANGLE
The compelling next experiment is what this level of ambition could produce with original characters and a setting the creator can keep developing.
