Couldn't open any of your zip files ("End-of-central-directory signature not found."). I put all your other sounds ingame for testing:
Very good sound, like it a lot, would consider it ready for inclusion.
Base sound is very fitting, the percussion between the base and exhaust sound should be removed though, it sounds odd in rapid fire (the exhaust sound might need to go closer to the base sound then).
Good sound, I'd take it as it is.
Doesn't work at all in rapid fire.
Sounds very noisy and doesn't really fit the gun. Maybe something a bit more futuristic?
is a packed pk3dir that you can unzip into the main
directory inside your home folder (~/.Unvanquished/main/
under linux) to hear the sounds ingame yourself. Have a look at the directory structure inside the pk3dir and you will know how to change or add new sounds there.
If you want us to include these sounds with the game, we would need you to release them under the Creative Commons Attribution-ShareAlike 3.0 Unported License
