Since I'm now a proud owner of a portable recording device with quite the quality (24 bit wav, 96 KHz) I can go around and do some recordings for your maps, games, whatever you need it for.
Keep in mind I can't record gunshots, explosions or similar stuff as all fun things are mostly illegal here.

As I just got the device I haven't recorded much yet but I'll put up a list here or on a Wiki page when I got somethingMost of my sounds will be up on my Freesound.org profile!
