I modified this plugin so the bullettime triggers off headshots and handgrenade kills too. Furthermore I replaced the sound with the old Eventscript sounds and increased the bullettime a bit!
//this activates bullettime on headshots - default: 1
bt_headshots 1
//this activates bullettime on kills with handgrenades - default: 1
bt_he 1
This is the first time I code anything so use on your on risk, but it works fine on my server! I did this just for myself but maybe someone appreciates the contribution.
! I renamed the plugin so u should remove the old one 1st !
