theres a sniper config in pak0.pk3 or something.
originally in patd.cfg (forget which pak its in since i didnt find it in the new ones :S)
bind CTRL "vstr snipermodetoggle"
seta snipermodetoggle "vstr snipermodeon"
seta snipermodeoff "-speed; -zoom; sensitivity 7.5; set snipermodetoggle vstr snipermodeon; echo Sniper Mode Off..."
seta snipermodeon "+speed; +zoom; sensitivity 6; set snipermodetoggle vstr snipermodeoff; echo Sniper Mode On..."
also some kinda cool rail settings... /exec whiterail
if you press ctrl, you will move slower, zoom in, lower your sensitivity and get a little console message. you will have to change the sens for +zoom and -zoom for your own whatever.
