1. I want to set the record straight on using high DPI settings on your mouse. You can see my write up on this at http://steamcommunity.com/groups/Gunslinging_Gladiators/discussions/2/846961716279722695/

2. The following is my "headshot" cross hair. It's a box that you put the person's head in, and shoot. It's the only cross hair that really seems to increase the number of headshots I get.

Here's a script I made to reduce voice reception volume to 20% (I've now adjusted it to 0%). It's a toggle based script so that you can use a single key, or mouse button, to toggle it.

alias voice_t "voiceon"
alias voiceon "alias voice_t voiceoff; voice_scale 1; say_team voiceon"
alias voiceoff "alias voice_t voiceon; voice_scale 0.2; say_team voiceoff"
bind "\" "voice_t"
