Right-click the "Unturned.exe", hover the mouse over "Send To", and click on "Desktop (create shortcut)".
Right-click on the shortcut and select "Properties". The "Target:" field should contain the path to Unturned.exe and should look something like this:
"C:Program Files (x86)SteamsteamappscommonUnturnedUnturned.exe"
Now, at the end of the string of text, insert this string of text:
-nographics -batchmode +secureserver/...
'...' is whatever you want to name your server - An example of a finished "Target" field:
"C:Program Files (x86)SteamsteamappscommonUnturnedUnturned.exe" -nographics -batchmode +secureserver/My server
Finally, run the server. A black console screen should appear, with no text.
