Anthropic's Claude Fable 5.2 demonstrated impressive capabilities by building a first-person shooter in just one prompt, albeit after eight hours of processing and a cost of $550. The resulting game, Saltline, was a rain-soaked port shooter featuring drone and robotic dog combat, as well as disabled communications relays. Anthropic engineer Felix Rieseberg shared the game, describing it as an experiment in the model's potential when given a single instruction.
The game's visuals were generated procedurally rather than through imported assets. A public mirror package condensed the game into a 1.4MB HTML file with integrated Three.js code. Rieseberg spent about two hours refining the weapon models, sounds, and gameplay before the final release.
