How do I pass command line options to ET via SLAC?
You may create a shortcut to SLAC.exe and use command line options as you would normally use with ET.exe (e.g. +set fs_game etpro). This also means you can point your server browser to launch SLAC.exe instead of ET directly. If you pass any command line option to SLAC.exe and you use auto-login (Remember me), ET will be started immediately upon logging in. Use this combination if you want to start ET directly without pressing the Start the game button.
