See, PD2 never really makes a big deal out of your armor being broken in vanilla, that'd make sense if health didn't matter, but it DOES! Armor is your only real method of guaranteeddefense in this game, it stops cops from just, shredding you at first sight, which is why I've always found it weird they don't try to make a proper warning when it happens.
In response, I made this mod, this mod dampens your audio slightly whenever your armor breaks, lowering the sound effects and letting the music take hold, which immediately warns you of your possible impending doom, and, if your health is below 20%, the effect becomes more intense, REALLY warning you to be careful.
Installation: Just like any BLT mod, just drop it right into the mods folder.
