Grappoli: a browser remake of the Quake 2 mod RailWarz
A non-developer used Claude Code to rebuild a 20-year-old Quake 2 capture-the-flag mod with grappling hooks and railguns as a browser multiplayer game.

The full story
RailWarz was a small Quake 2 mod the maker played as a child: fast capture the flag with grappling hooks and one-shot railguns. Not a software engineer, they used Claude Code to make their own version, Grappoli, which runs in a browser on their own server, with an Italian twist.
They say a basic version had players moving, hooking and shooting each other on a local server within an hour or two. Most of the remaining effort went on look and feel: travel-poster art direction, maps based on real kinds of places, and AI-generated announcer voice lines.
