You could switch off the sound thingy in the Customize-section...I don't know if you want to hear all those screaming newbies...
And have you noticed that more headshots are made...? I think something's wrong with the hitboxes...
More news...PunkBuster has stopped further development of their anti-cheat software...because Valve won't co-operate...I'm very disappointed at that...
...especially since new wallhacks and aimbots are out now...
...damn cheaters...
