AI Built a Full-Fledged Shooter in 8 Hours, and It’s Playable in a Browser

An Anthropic engineer used the company’s new Fable 5.2 AI model to create Saltline, a browser-based first-person shooter, in about eight hours without writing a single line of code by hand.

Anthropic has demonstrated Fable 5.2, and users are already testing its capabilities. The engineer created Saltline using the model.

The shooter was generated entirely through “vibe coding,” a method of creating software with ordinary text prompts through the Fable 5.2 interface. The model generated the textures, sound and 3D models for all objects used in the project.

Saltline runs in a browser using code executed on a web page, so there is no need to download an executable EXE file.

AI is also changing the gaming industry. In recent weeks, enthusiasts’ work on emulators and native PC ports of console games has accelerated. New tools have enabled unprecedented progress, with some Switch 2 exclusives now running almost perfectly on computers just days after release.

This could also affect the balance of power in the market. It may prompt PlayStation to return to the idea of releasing its games on PC. According to leaks, even GTA VI could come to PC a few months after its console release. That possibility has been linked to advances in AI tools.
