Sound Files

This isn’t necessarily about Garrys Mod but where would I need to go to find the voice files for games like Half Life 2: Episodes 1-2? I’m trying to make a movie and I need Rebel voices and Combine chatter. If anyone can help, thank you!

2:open up the hl2 ep1/ep2 GCF
3:extract all the sounds you want
