JEV ARCADE

That claim is the interesting part and it is unexplained. The page states that no key is stored in the browser and that there is no silent AI fallback when Jev is unreachable, which implies requests go somewhere the visitor never sees. The source page renders only a title, so the mechanism is not documented anywhere you can check without reading the compiled bundle.

Combat and the match clock freeze, so a stalled connection stalls the duel rather than letting a script continue playing for you. That is a deliberate honesty choice, and the practical consequence is that a dropped request can leave you frozen in place until it resolves.

Not from what is published. No author, repository, or licence is named, and every description lives inside the compiled app bundle rather than in page text or docs. Reusing the option sets would mean reading them off the network requests yourself.

The stated goal is 90 seconds of survival with eight bullets grazed to charge the Pulse, in a mode separate from the Rustline duel. Rustline has four documented difficulty modes; nothing says how the graze requirement or spawn rate scales in Neon Gauntlet, so the difficulty is not documented.

First to three rounds at 100 HP with a five-round bolt-action, across four difficulty modes. Those are the numbers the page states. The maps, the reload timing, and what the four modes change are not written down anywhere you can check, since all of that copy lives inside the compiled app bundle rather than in the page text.

It chooses a tactic from the options that are legal in the current state. Movement, physics, and the legality check are authored game code, so the model never emits positions, velocities, or timings. The page's rule is that a reply that has not refreshed within four seconds freezes combat and the match clock rather than letting anything improvise.

Nothing to install. It is a hosted web app on Vercel at jev-arcade.vercel.app/duel that you open in a browser, with no package, CLI, or repository to pull. No author, license, or cost information is published for it either, so there is nothing to point an issue at.
