Example Startup Command [#example-startup-command]

```
AbioticFactorServer-Win64-Shipping.exe -log -useperfthreads -MaxServerPlayers=6 -PORT=7777 -QueryPort=27015 -ServerPassword="secret" -AdminPassword="adminpass" -SteamServerName="My Server" -WorldSaveName=Cascade
```

Panel Startup Fields [#panel-startup-fields]

On XGamingServer, common parameters are exposed as fields in the **Startup** tab:

| Panel Field     | Maps to Parameter   |
| --------------- | ------------------- |
| Server Name     | `-SteamServerName`  |
| Server Password | `-ServerPassword`   |
| Max Players     | `-MaxServerPlayers` |
| Query Port      | `-QueryPort`        |

For parameters not exposed in the panel (like `-AdminPassword`, `-PlatformLimited`, `-WorldSaveName`), check if there's an **Additional Arguments** or **Startup Command** field, or contact support.
