Well well, I finally had the change to try out the latest SVN version of nexuiz that includes your sounds, Tenshihan
I really like a lot of the sounds you did - good job man. But one thing that really bugs me right now is that there doesn't seem to be ANY balancing of the sound volume levels at all. When playing v2.4.2 I have the feeling of having some kind of 'constant' sound level/loudness. In current Nex SVN, this is absolutely not the case. Especially the mixture of old sounds with new sounds doesn't work at all, and this comes out very clearly when using headphones.
Just to mention examples: I can barely hear the switch-weapon-sound or the weapon-pickup-sound. There are a lot more other things that feel weird but would need more time to figure out what exactly it is. Apaprt from that, almost all of your sounds use very high frequency areas and I feel like I am only having swooshing sounds from a science fiction movie around me, I miss the bass and midtones a bit
This is just my very own critical opinion, so you can also just ignore it

. I tried to be as honest as possible.
