Since I first played, I was pretty impressed with quality of the audio on this game.
When I saw a line listed for audio tweaks/fixes in the newest change log, I put on my Sennheiser's and took a prowl through the game again.
I'm really digging the new voice/sound effects in PVP, not sure where else they may be present.
Good job, STS! I'm glad audio isn't just an afterthought for this game like it is on so many others.
