I tried looking for a mod that does this but to no avail. Its kinda suprising tbh but anyway just a mod like morescreams but with walkie talkies. The walkie would stay on if activated and the player dies, delaying or removing the static noise.
I think hearing whatever monster killed them walking away/the death of your friend through the walkie with morescreams would be much more terrifying than just the static after the player dies.
(If this already exists please let me know!!)
