Upon killing an enemy player, a notification pops up in the middle of the screen, e.g., "Killed PLAYERNAME ##" with a number. These numbers appear to be out of 100 and to contribute to being "on fire".

What are these numbers? The damage percentage that you contributed to the kill? If you headshot a 100 HP player who only has 1 HP left, would you get "1"?

I've been digging around to try and answer this question. From what I've found, the number appears to be an percentage of the amount of damage you did to that person.

Some other sources saying its percentage based:

If you headshot a 100 HP player who only has 1 HP left, would you get "1"?

Based off the sources I found, I would have to say yes since 1% of 100 would be 1.

The number represent the amount of "Firepoints" you get with the kill (like Nutty said in the comments).

The amount of point you get is calculated from the perfentage of damage you made to the enemy.
