Trivia[]
- Player can only get up to 4 Kills FX as maximum in normal modes. However, there is a total of 5 extra kill voices found in the game files which can be achieved in Human Scenario only.
- There was a wallbang Kill FX, but it was removed after Open Beta. However, it was added again in Counter-Strike Online 2.
- Despite special KFX available for various circumstances in Zombie Scenario, all kills use the regular KILL notice.
- Getting a multiple kill in one shot counts for only one kill FX. For example: Killing a second opponent will cause a "Double Kill", and then killing two people with a shot afterwards will cause vox announce "Triple Kill" instead of "Multi Kill".
