# Anthropic's Fable 5.2 One-Shots a Playable FPS Game in Just 8 Hours > Source: > Published: 2026-11-10 09:14:30+00:00 The power of frontier AI models is increasing, and the gaming realm has already experienced what AI can do in terms of mods, changes, bug fixes, and many other aspects when a powerful model is put to work. Late last night, Anthropic released its most powerful frontier model, Fable 5.2, which brings the best intelligence from the company's offerings into an API. As a demonstration of this model's capabilities, we are seeing a relatively complex first-person shooter developed from scratch today. This includes models, sounds, and textures, all created by Fable 5.2. It took about eight hours, 445 million input tokens, and about 2.7 million output tokens, totaling around $550 if done through an API. The result is a game called "[Saltline](https://claude.ai/artifact/BGY1SztrAYcJQHSsnHHGmp)," which can be played entirely in a browser through Claude Artifact, a platform used to showcase creations. Below you can find the "Saltline" game, where the objective is a simple mission to cut three relays while being constantly attacked by an army of robot dogs and drones. After completing the objective, the main character reaches a boat, and the mission is complete. While this is a very simple task, the fact that Fable 5.2 accomplished all of this from a prompt is an amazing achievement. It can deploy thousands of agents to get one thing done, and with better descriptions, it can perform tasks much closer to what you have imagined.
