thermobaric ammunition :D also scifi sounds for weapons maybe even some more reloading sounds and other utility sounds

also voice lines for crew members that can be changed, even set to "" for no voice line at all

I'm all for adding more sounds. Sci-fi and reload sounds included.
Thermobaric too.

Regarding crew voices, the death sounds can already be changed with the sound replacer. I will probably leave actual crew voice systems to the players to create

that is alright

incendiary cluster munitions
