I think that you guys are doing some amazing work with the maps you're making so I thought i might try and help out by lending my voice for some sound effects you people might want. This is an example of what i mean:
It might be a computer or a recording that keeps looping on a command console somewhere in the map. I can make it audiable or just a creepy scratchy sound that doesn't make much sense. In any case if you need something just ask and I can sample something for you.
keep up the great work guys. All hail the ns mapper!
