My second sound mod changed the killsounds like Doublekill, multikill ... to quake sounds, the most will say they are from counterstrike, but they are from quake, anyways ... All sounds are female^^
The Sounds i changed:
First Kill->First Blood
Doublekill->Rampage
Multikill->Killing spree
Ultrakill->Unstoppable
Fantastic->Godlike
Unbelievable->Wickedsick
Nutshot(only male)->Humiliating defeat
(some sounds could have a bad quality, because the combat arms sounds have a bad quality :S)
