Haptics require phone or controller vibration support. Unsupported browsers keep this preference but cannot vibrate.

Stored only in this browser. Server addresses and passwords are never saved. Mouse, sound, visual, and player-name changes apply immediately. Overall sensitivity 1 and yaw/pitch factors 1 preserve the default response. A negative yaw factor reverses horizontal look; inversion changes the pitch sign. The quick slider spans 1/128–128, while this numeric field accepts any positive finite value. Field of view 90 matches the legacy clients (67.5° vertical). HUD placement, crosshair styles, and effect density match the current native Rust client. Third-party licenses.
