Saltline

GAME BRIEF

What's the game?

The title card reads 'Port Authority Breach Unit, Saltline Terminal, 05:42' and gives you one job: the port's security net has gone feral, so cut its three uplinks and reach the boat. You fight through the stacked shipping containers and under the cranes with a rifle you can aim down the sights, against four-legged security robots on the docks and drones overhead, and cut each relay with E. Felix Rieseberg, who works at Anthropic, made it to test Claude Fable 5.2 with one-shot prompts and no human feedback. He says the models, sounds and textures were all made from scratch, and that the run took 8 hours and about $550 at API prices.

What to expect

Free, with no sign-up: it's a shared Claude artifact on claude.ai, and the Sign in button at the top is optional. The title screen says every surface, machine and sound is generated in your browser, and the whole game came to about 2.2 MB in our check. While it builds the scene it shows 'stacking containers' for a few seconds, then the title screen with Deploy, Settings and Controls. claude.ai labels the page as user-generated content. Felix posted it on X on November 9, 2026; the post had about 2 million views the next morning.
