Extracting Sound

[880753]

How would one find/extract a sound from Half Life 2? I am looking for the sound of the citidel alarm. I can find them in hammer but cant locate them on my local disk. Any help?

Download GCFScape

This allows you to open Valves cache files (models, materials, sounds etc).

Which are located in your 'steamapps' folder.
You should fine a file called source sounds.gcf, open that using gcfscape and find your sounds and extract them.
