About SaltlineGame.pro
About SaltlineGame.pro: what this site is
SaltlineGame.pro is an unofficial fan guide to Saltline, the browser first-person shooter that Claude Fable 5.2 built in about eight hours from one short prompt. Felix Rieseberg shared it on November 9, 2026, and it quickly became the best-known example of what the new model could do.
We run a copy of the public build right here, and the original artifact is still on claude.ai. The game has a striking title screen and a short note from its creator, but no manual, no walkthrough and no explanation of how it was made. That is the gap we fill: a fast way to start playing, a walkthrough with every control, the prompt and the numbers behind the run, and a list of other games made with Fable 5.2.
What we cover
- Saltline game: what it is, how to start, controls and FAQ.
- Saltline walkthrough: modes, difficulty, the three relays, the boat and performance fixes.
- Saltline prompt: the instruction Felix gave the model, line by line.
- How Saltline was made: the eight-hour run, the token counts and the reported cost.
- Fable 5.2 games: other browser games made with the same model.
- Make a game with Claude: how to try the process yourself.
How we write our guides
We work from primary sources: the game's own screens, the creator's public posts, and the official artifact page, which we open and screenshot ourselves. Where we rely on reporting, such as player complaints about stutter, we say so. Numbers that come from the creator, like the run time and the bill, are labelled as reported. We do not copy other sites' text, and descriptions of other games are written by us.
Saltline is a small game and may change. Its creator has already released an improved version alongside the original one-shot build. When something changes, we update the guides and the date in the page data.
What we do and do not do
We host a copy of the public Saltline build so it can be played in the page, and we link to the original artifact. Gameplay is unchanged; the only code change routes the built-in one-shot button to our own copy. We claim no rights in the game: Saltline belongs to Felix Rieseberg. If its creator asks us to remove the copy, we will. We do not use Anthropic logos and we do not claim to speak for Anthropic or for Felix Rieseberg. For official information, go to the creator's post or the original game page.

Who runs SaltlineGame.pro
SaltlineGame.pro is run by a small independent team that builds and maintains guide sites for browser games and tools. We are players first: we opened Saltline the day it went viral, waited through the loading screen like everyone else, and wanted one page that answered the obvious questions. How do I start? What are the controls? Is there a mobile version? How was it made, and what did it cost? This site is that page, grown into a small set of guides.
About SaltlineGame.pro in one line: a fast, honest, unofficial guide that sends you to the real game and helps you get more out of it.
