I dont want to use gunslingers addon
Could you make a small pbo with it ?
;D
If ya don't wanna use any unofficial editor addons/upgrades/updates, whatever-'ates,
then how the bell did ya ever get to know 'em

isn't it from one of those
editor addons? (hek - maybe its kellogg's editor update & not 'slingers... anyways..)

I couldn't make it coz I dunno the cofiurations for it, matey :-\

Locate the cpp stuff, and I promise you'll have those silent bottles within a second.
You could even add a custom "damage sound" ( not sure with bottle objects, but I guess so ).
Still, without the config I can't make sh|t, man!

sorry!
