Remove a 0 and you know the kills of a slayer game, hard man, just hard. The special points you get do nothing for slayer score. Look at the scoreboard, you see that number to the right of your points. Thats kills, if its 8 you given your team total 80 points or 8 kills.
I hope this clears up all the -Yoink!- post saying how they hate slayer working off points. It does not, when you do an assassination and it gives you 20 point for the style, it does not give your team 20 point toward victory, it gives 10 point (1 kill).
