Well, I don't know if I am really adding something new here, but in my old files I found a patch that someone made for reinstalling the original alien death screams (from version v1.2 and earlier) to the newer (v1.4) version of X-Com. As I like that old screams more than the newer ones, I made a test adding the two files to the OpenXcom Data/sound folder and they worked!
So, if you prefer the first version of the alien "voices", here are they...
