The location of all files is X:\Mission 8\main:

1. The original sounds for stand-alone and online (including upgrades and skill sound effects) are in iw_13.iwd, here It should be noted that this file needs to be renamed, and iwd needs to be changed to rar. If you do not see the iwd suffix, please see the modification method below, and then modify it to a rar file and unzip it.

After decompression, both the online and stand-alone original sounds are in the music, and the online sound effects are in the mp file. 2. The online voices are divided into Maozi, PMC, SAS, Delta and GIGN, African Black Uncle and Makarov's group. Among them, Maozi, PMC, Makarov troops, GIGN, and SAS are all in main\localized_english_iw01\sound\battlechatter (ocalized_english_iw01 also needs to modify the suffix name)

fr=GIGN, IC=Makarovna Group, PC=PMC, ru=Maozi, UK=SAS. All sound effects are in the MP files of these files. Delta's is in main\localized_english_iw02\sound\battlechatter\US\MP, and MP (the battlechatter file also contains part of SAS). African Black Uncle's is in main\localized_english_iw00\sound\battlechatter\af\MP

Of course, after finishing, you need to change the modified rar to iwd. Otherwise, you will not be able to enter the game
