I’ve noticed in Halo 3 the weapon-firing volume is way too low, you can hardly hear them unless you turn up your volume a lot more. In Halo 4 I’ve also noticed some weapons sound softer than others which wasn’t the case on H4 X360, i.e. the assault rifle has become softer when firing and louder when reloading. Overall there’s quite a few volume issues over the games you might wanna check up on.
I have noticed this as well. I have also noticed this when playing Halo 2 Classic. Hopefully this along with all the other bugs will get patched.
Yeh, I think this game has several volume issues, both guns and voices can sometimes be pretty low.
