No Zombie Aggro from Firearms (Silence - Silent - Suppressed Gun Sounds)

No Zombie Aggro from Firearms (with optional Silenced Gun Sounds)
This mod makes guns quiet to zombies.
When you shoot, zombies will not notice or attack you.
Guns use the same “no aggro” setting as the crossbow, so they act like silent weapons.

Two Versions Available
You can choose which version you want to install:
1) Version A: No zombie aggro with silenced gun sounds. Guns sound quieter, closer to how suppressed weapons should feel.
NOTE: Assault rifles and SMGs still use their normal sounds.
The silenced pistol sound does not apply to them, likely because they are full auto.
To avoid complete silence (no sound at all), their original sounds are kept.
This does not affect the main feature: zombies will not react to any gunfire.
2) Version B: No zombie aggro with original gun sounds. Guns sound the same as in the base game, but zombies still ignore them.


Installation
1) Download one of the main files depending on how strong you want the night vision effect:
no-aggro-silenced-weapons (v1.0a) = no zombie aggro, silenced weapon sounds
no-aggro-unmodded-weapons (v1.0b) = no zombie aggro, original weapon sounds
2) Extract downloaded .zip file.
Inside you’ll find data7.pak.
3) Place data7.pak into your game folder:
...\ph_ft\source\
If you already have a file named data7.pak, you can rename this one to data2.pak, data3.pak, data4.pak, data5.pak, or data6.pak instead.
If all names from data2.pak through data7.pak are already taken and you don’t want to replace your other mods, you can merge them together.
In that case, follow the merging tutorial linked below to combine them.
