Yeah, the sounds are pretty fantastic in almost all areas. Rifles pack a punch, and the distant cracks of gunfire are really nice. Hearing the artillery and gunfire up above echo through the tunnels on Fallen Fighters is awesome. Even the much maligned battle chatter adds a ton of atmosphere.
The only real weaknesses for me are:
- Grenades. Really quiet unless you're standing right on top of them. A grenade explosion 30m away can sometimes seem inaudible. A rifle firing in the distance will be much, much, louder in comparison.
- Tanks still sound weak to me, but to be fair they're much improved compared to the stealth tanks of RO1.
- The high ROF guns like the PPSH and MG34. Rather than spit out a sound effect for every bullet fired, these guns will play a loop sample until you stop firing, at which point an 'end' sample is played. Problem is, these aren't blended together all that well. When firing short 2-3 shot bursts it's especially apparent as one sample interrupts the other. Furthermore, most guns in the game have some element of reverb. A rifle will be a hefty bang followed by a longer tail as the sound trails off. The PPSH/MG34 sound like on/off switches in comparison. It can be jarring as these two guns sound like they're in completely different environments to the rest of the weapons. For what it's worth all of this applies to RO1 too, but heh...
Just my two pents. Sorry if it sounds like I'm being overly critical, but it's only because the sound work across the board is generally so well done that the flaws stand out.
