let me welcome you here
:laff: WELCOME :laff:
here it goes you register a game you own whit the CD-key (HL or CS must be legaly bought)
then you download HL and it will automaticly install itself to steam
you have to run it once so that STEAM can configure all files neaded to play
then download ESF 1.2 and install it to your HL directory (should be set by default)
after that get ESF 1.2.1 patch and install it to the same directory as ESF 1.2
then just dubble click the shortcut on your desktop and have fun playing
