While Hawk's Soundpack is one of the best and most complete gun SFX packs for Payday, as some of you may know, it doesn't cover the akimbo shotguns and SMGs.
As a test, i made a quick mod patching the akimbo judges to use their single counterpart's SFX to see how easy it would be.
As it turns out, very. Took me less than an hour to put this together. I may make a dedicated mod patching all the akimbos missed by Hawk's in the future.
To install this, just drop the .bnk file into the same folder where you have the rest of Hawk's .bnks at in your mod_overrides folder. You could also keep it in the individual folder i've packaged it in, if you're a crazy person.
