About the game
Saltline is a single-player, first-person shooter game made with Claude's Fable 5.2 model, set inside a container port whose automated security has turned hostile. You enter at first light, move through industrial cover, and fight your way toward an exit. The Saltline game runs directly in your browser, so there is no launcher to install and no account to create.
In Mission mode, your objective is clear: cut three relays and reach the boat. If you prefer a longer test, Holdout replaces the escape route with increasingly demanding enemy waves. Saltline combines a compact setting with movement, aiming, ammunition management, and a readable objective system. Start slowly, learn the terminal, and make each reload count.
Choose your mode in the game menu before you deploy.
Breach / Cut / Extract
Three relays. One exit.
Mission gives Saltline a beginning and an extraction objective. Follow the relay markers, use containers to interrupt enemy sightlines, and hold the interact key near each relay. Cutting all three uplinks is only part of the job: you still need to reach the boat. Take the route at your own pace instead of rushing through exposed lanes.
Best for your first deployment
Survive / Resupply / Repeat
Stay for the next wave.
Holdout turns the Saltline terminal into an endurance challenge. Enemy waves keep growing, and the breaks between them give you a chance to resupply. Preserve ammunition, pay attention to the space around you, and avoid letting pressure build from several directions. A familiar corner may feel safe until the next wave forces you to move.
Best for another run
A short field guide before you cross the fence.
Press Play Saltline above, wait for the Saltline menu, then select Mission or Holdout. Open Settings before deploying if you want to adjust quality, volume, sensitivity, or field of view. Start with a lower quality setting if the scene feels slow. A desktop keyboard and mouse offer the clearest introduction.
Use W, A, S, and D to move and your mouse to look around. Left click fires; right click aims. Sprint with Shift, jump with Space, and crouch with C or Ctrl. Saltline rewards knowing where the next piece of cover is before you leave the last one.
In Mission, approach each marked relay and hold E to cut it. Reload with R when you have breathing room. Switch weapons with Q, the mouse wheel, or the number keys 1 and 2. Saltline has both a rifle and a sidearm, so an empty magazine does not have to end a run.
After the third relay, follow the extraction objective toward the boat. In Holdout, use each lull to resupply and prepare for the next attack. Press Esc or P to pause. If the mouse feels trapped inside the Saltline game, Esc releases it so you can return to this guide.
An AI-built FPS with a complete mission and a replayable survival mode.
Stacked containers, open lanes, and industrial structures shape how you move. Saltline gives you an environment to navigate rather than an empty arena. Read the next stretch, break line of sight, and choose when to cross it.
Aiming, reloading, weapon switching, sprinting, crouching, and close-range attacks all belong to the same compact loop. Saltline keeps the controls familiar so the challenge comes from using them under pressure, not learning an elaborate interface.
The settings include multiple graphics quality levels, mouse sensitivity, audio volume, and field of view. Saltline can be adjusted before a Saltline run. If you lose smooth movement, reducing graphics quality is a useful first step.
Saltline is the first-person shooter game made with Claude's Fable 5.2 model. Felix Rieseberg shared it publicly, and the linked Hacker News discussion introduced the same browser FPS. If you arrived through a Saltline Claude search, this is the game those posts describe.
The Saltline Claude story comes to life in a compact 3D port, a working combat loop, generated sound, and an objective you can finish. The game uses Three.js for rendering. Play the standalone version here, then use the field guide to learn the controls, complete Mission, or prepare for another Holdout run.
This is an independent Saltline game site. The original creator post and community discussion are linked here for background and credits. You can play without opening Claude or starting a chat: load the game, choose a mode, and deploy into the terminal.
