List of CS:GO Soundscapes
To use soundscapes in Counter-Strike: Global Offensive is very similar to what it is in all other Source Engine games. An easy way of testing them is to use the playsoundscape console command, which includes limited searching for soundscape names so you shouldn't have to print out a copy of this list for reference. Some sounds that are prominent when you use the playsoundscape command may not be so overbearing in a custom soundscape.
There is not yet a complete list of soundscapes for Counter-Strike: Global offensive.
The soundscapes in Counter-strike: Global offensive is similar to the ones in Counter-Strike: Source. Therefor you can use the List of CS:S Soundscapes until this list gets written. And if you can't find them all in the Counter-strike: Source list, you can search for them in the console as mentioned above.
If you don't know how to place soundscapes in your map, please visit the soundscapes page.
