Half-Life 2 Sounds
September 1, 2006
Just in case you're wondering, I recently worked out how to extract sound and other media files from Half-Life 2. It's fairly easy - grab the free tool GCFScape and it does all the work, opening up the GCF files that HL2 uses to store its assets. You can find all the sounds and music in:
Valve\Steam\SteamApps\source sounds.gcf
What you do with them once they are extracted is completely up to you.
