Project Claims

Statements by a project are not independent verification.

Verification Details

No completed gameplay session has been independently verified. We have no measured FPS, browser compatibility or working multiplayer result to report.

Link status: Link reachable; checked 2026-10-09. A reachable landing page does not establish that a game starts. In-page embedding: Unknown.

The landing page and in-frame asset downloader worked in Chromium, but the runtime says Quake III data must be legitimately obtained. Without a licensed copy, no embedded session or controls were verified.

Setup instructions

  1. Open the linked project and review its current instructions.
  2. Its landing page offers a player-name field and a Play button. Gameplay beyond this screen has not been tested here.
  3. Confirm the asset requirements and controls on the project before joining.

These are preparation checks, not a tested walkthrough. Follow the project’s current instructions if they differ.

Troubleshooting

The menu loads but the game does not

A working landing page does not prove a working game session. Check the project’s current instructions and note any visible error.

Frequently asked questions

Does it support mobile and controllers?

The project advertises both. Neither has been independently tested by this index.

Is multiplayer verified?

The project presents multiplayer as a feature. We have not joined a session or verified its servers.

Sources and check notes

  • Quake III project landing page ↗

    The page credits Q3JS and advertises multiplayer, mobile and gamepad support. A Chromium iframe test from this site’s production origin reached the asset downloader, but gameplay did not start. The runtime noted that pak0 must be legitimately obtained through purchase; the download was stopped without a licensed copy.
