So I've been playing this for a while now (got 78 Hours clocked on Co-op so far). and I have to say.... ouch my ear drums
the game is so darn loud, its hard to hear voice chat 90% of the time.
Biggest issue is that you only have 3 voice adjustments;
- Master Volume
- Music Volume
- Voice Receive Volume
The Master Volume also lowers the Voice Receive Volume and because of this you can never manage to turn the game lower then voice chatter. and nearly all sound effects are way louder then voice chat by default. and right now, I can barely hear my team mates talk while artillery shells, even at a great distance, hurt my ears.
TL:DR; Add a SFX Volume Slider please!
