I dl'ed unsound from fileplanet, but could only open the uax's. My knowledge of Unreal isn't that hot, besides it being my favorite first-time-through games ever -- IMHO has almost no replay value :-(
Read about UnrealEd but don't have it with my install. Downloading UnrealEd now, so hopefully...
Was thinking about recording the bg sounds during gameplay, but that would include music.
As far as I know, all images and sounds for video games are intellectual property, and although it would be nice to just take it, I get permission first. If you're pissed about being the first Zombie, imagine how I felt when I heard one of my tunes used for a Flash intro on someone else's site!
