yea, no way to do it other than editing the paks to delete the wav files (not worth it)... in baseq3/osp/cpma at least. some mods seem to add the command "g_announcer" but it looks like you're out of luck. i'd suggest getting better at ctf and it won't happen very often
I'm plenty old enough - thanks. A Q3 frag buddy plays without headphones and his kids are picking up the occassional audio clip. He asked in a Q3 forum if anyone had a suggestion to turn off the foul language so I came to the best q3 resource there is!
As if the constant grunts, moans, death sounds and gunfire sounds are a good background noise with children around. They'll wonder what you're doing before they hear "Holy shit!"...
