Remember I played a mod a long time ago with only suppressed weapons. Apart from the bullets hitting the ground, you couldn’t hear the firing sound from a certain range.
I did some testing in the editor back then I remember it was around 25-30m.
Today I come to think about it again. I had a fight where I was surprised one enemy didn’t sneak up on me, since I was farming the objective for several minutes but I realized he couldn’t have heard me.
So I checked the replay file and in all the chaos around him, the sound from my firing PPD-Bramit was inaudible.
Pretty cool, that it works so well! Not only against bots apparently.
Thought it would be nice to share.
