Neptunia Dogoo - Common Infected Sound replace

This mod replaces the sounds from the common infected with the Dogoo (Enemies in Hyperdimension Neptuia) sounds.

I recommend this mod because the sounds don't fit to the default zombies:

This mod works without extracting the .vpk file, but it's be a little buggy (first video).
The second video shows the mod exctracted.

How to extract the mod:

1) Extract the file "792643566.vpk" with this program: https://developer.valvesoftware.com/wiki/GCFScape

2) Put the folder "sound" in the folder "steamapps\common\Left 4 Dead 2\left4dead2" and replace all files.

3) Start the game and execute the following console command: snd_rebuildaudiocache
The game switch into the loading screen and then you have to wait a few minutes.

4) Restart the game and disable the mod in the game.
