Well, after I first saw LiquidForce's custom Halo accolades, it dawned on me--I should totally make the Quake ones that I always here when I play CS:S! So I hopped in my Steam folder and fished out the package of Quake sounds that servers use and worked my magic! Granted, the Quake killcombo system is a little different than CA's, but I managed to make it work well enough.
++Updated the image sizes, so now they should appear to be the correct size with no chopped off letters!
Round Start - Prepare to Fight
Headshot - Headshot
Nutshot - Humiliation
First Kill - First Blood
Double Kill - Dominating
Multi Kill - Rampage
Ultra Kill - Killing Spree
Fantastic - M-M-M-Monster Kill
Unbelievable(+) - L-L-L-Ludicrous Kill
I didn't feel the need to actually upload the actual .rez files because that would take too much time and there is no sense in wasting MPGH's bandwidth on trivial things. All you have to do is inject the files into the designated folders that I have already planned out for you. You can get the injector here. If you are too simple to figure out how to inject them, just read the tutorial on that page.
Dunno if I need it, but:
