Constant, extremely high-pitched sound started as soon as the elevator opened and stopped when I loaded back into Fortuna.
Neat

I don't think it's been changed yet, if indeed it ever will be.  I didn't even have to check my teammates' loadouts on ESO this morning to know that someone was using it.  Absolutely earsplitting.

I've heard good things about the weapon, but largely wrote it off for my own purposes after hearing its sound effects.  They're really overtuned.

We have not issued any updates for this yet, but are looking in to the issue. Thank you for your patience. 

Thanks for the follow up. We have isolated the issue and will have a fix.
