HalflifeHDsoundpack addon

This is the Half life HD soundpack
All the sounds are extracted from Counter strike Condition zero Deleted scenes.
That means that all the credit goes to the CSCZDS developers.
Rogue Entertainment, Gearbox Software, Ritual Entertainment, Turtle Rock Studios, Valve Software

DONT FORGET TO BACKUP YOUR SOUND FOLDER
Extract the valve folder into your Half life game folder. This should work with all versions of Half life and mods.
In my case its: C:\Steam\steamapps\common\Half-Life
If you dont want to overwrite the original files rename the valve folder to valve_addon. However the sound will then work only in the original Half life.

You can also change the name of the folder to just a specific game/mod
For example
instead of valve it can be: bshift,cstrike,czero,czeror,dmc,dod,gearbox,ricochet,tfc or more

Have a nice time playing
