This is going to be a very short and simple guide on how to extract DoTA 2 sounds from Steam. This will be useful to you if you are after either the heroes voices or are wanting the musical soundtracks for a certain project, or for plain enjoyment. Steam doesn’t let you have access to the sound files right off the bat, instead they are compiled into a directory which is a rather peculiar file type ‘.vpk’.
In order to access the sound files you will need to download GCFScape. Now I know the site looks dodgy as fuck but don’t worry the download is safe. Find the latest version, click run and follow the installation wizard.
Open the following file: <Steam installation path>\Steam\steamapps\common\dota 2 beta\dota\pak01_dir.vpk
This should bring up GCFScape displaying a selection of folders. Select the ‘sound’ folder.
Search for the file that you want to use, right click on it and extract to where you want to store it.
You now have your desired sounds from DoTA 2 on your hard drive and can do what the hell you want with them!
