Today, while I played Nex, I was thinking two things regarding the sound in the game. First, some of the weapon sound effects are kind of dull and don't really give a kind of kick that you experience in other games. The shotgun, mortar, hagar, and, especially, the uzi seem to suffer from this - they just don't have a sharp sound like you'd expect them to. I know there's been a lot of debate over the mortar sound, but I think all of them could be improved upon somehow.
Another though was regarding the music. The music is very good, of course, and I like to listen to it even outside of the game. However, for one thing, it's a little limited in the styles used, in that it's pretty much all synth techno, where, in many other games, there is a variety of orchestral, rock, techno, and sometimes blends of all of these. Orchestral might be pushing it a bit for a free game, but some rock or techno-rock tunes would be nice - this brings me to my next point that the music doesn't really motivate you in the game. In some games, when you hear a map's song start to play, it gets you real pumped up due to its high speed and energy, but Nex's doesn't really do that effect. It's enjoyable, of course, as I've said, but the particular tracks used seem to be lacking in energy.
I don't know how much can be done about these by the team, but they're just some suggestions.
