Here is a video, turn on audio:
The default stomper death audio sounds like gurgling grunts. This mod replaces them with longer screams.
Compatible with the new stompers added by the Behemoth Enemies mod.
If you want to compare the sounds, the old sound files are on your computer in Factorio/data/space-age/sound/enemies/stomper/.
I obtained these sound files by using free online AI sfx generators.
