People are starting to put out things they built with Claude Fable 5.2, and one of them already runs in a browser.

Saltfire, from Higgsfield, is an armed offshore powerboat racing game you can open and play in the browser: four tracks, three hulls, machine guns and rockets, heavy water physics, and five AI rivals on open water with no roads. It was built in three.js.

Higgsfield also showed an open-world 3D action game with a three-act boss fight and cutscenes, and a 90-second 2.5D animated duel.
