Could you maybe make a standalone addon for only the AR2 ball explosion? i absolutely love the sound out of any other kinds of this but this addon would conflict with other sounds i have replaced for the AR2.

Do you have any other mods to replace these same sounds?
You can try this:
Delete folder "3308647642" in "Steam\steamapps\workshop\content\4000"
and then resub, Restart gmod after install.
Also you can clear gmod folders like "cache", "download" in "GarrysMod\garrysmod"

for some reason it still has the normal ar2 shooting sounds

its part of AR2 Remaster

Where to get the new muzzle flash?

it's just a sound replacement, separated from the AR2 Remaster addon.

new effects?

Ty so much!

great sound work man
