This was created from scratch. I'm not very good at scripting. I'm still learning.

This script contains the killstreaks:

10
20
30
40
50
60

Everytime the player reach one of these numbers. It announces that the player is on a killstreak in chat.
This script is good for TDM/DM Servers

Here are the rules

#1 Do not copyright.
#2 Do not edit and re-release
#3 You can use on your server.
#4 Give credits.
