If you notice, every time you kill someone, UT displays a me age (such as "You killed Alarik") in the center of the screen, which takes 3 seconds to fade out. If you are able to get another kill before the first me age fades out, you get a "Double Kill" announcement and indication. If you get another frag before that one fades out, you get a "Multi Kill", etc. The breakdown is:
2 kills: Double Kill
3 kills: Multi Kill
4 kills: Ultra Kill
5 kills: MONSTER Kill (this one's great: The voice says "M-M-MONSTER Kill")
[bullet]Spree:
A Spree is defined as a certain number of frags without dying yourself. The indications are based on multiples of 5 frags, and the breakdown is as follows:
5 frags without dying: Killing Spree
10 frags without dying: Rampage
15 frags without dying: Dominating
20 frags without dying: Unstoppable
25 frags without dying: Godlike!
It's one helluva trip to reach the "Godlike" level - on anything but the most basic bot skill level, of course.Killing Spree
