So I tried to remove playerquotes by commenting some calls to some dlc_vox csv's, and I'm now getting freezes in game whenever a quote would have played, is there a proper way to remove quotes or have I done something wrong?

Lol thats to much work. I always thread this under maps\_zombiemode::main();

thread always_speak();

Then at the bottom of your mapname.gsc just add this:

always_speak()
{
while(1)
{
level.player_is_speaking = 1;
wait .1;
}
}

Works like a charm.

That still makes it, so when you revive player in co-op, player plays revive quotes. Other than that, yeah it works

I had to modify various scripts in order to remove all VOX calls it's rather tedious but if you want to replace the vox with your own it's worth it.
