How is KDA figured in firefight?

Games Halo 5: Guardians

So I decided to challenge myself and go through a firefight match without firing a shot. All I did was go for splatters in scout hogs, ghost and wraith. Well I did pretty good. 74 kills, 3 assist, 3 boss takedowns and only 8 deaths. My KDA came out to negative seven. Then some one else who had a KDA of zero had 21 kills, 18 assist, and 6 deaths…

Kinda strange. But it was fun doing firefight without shooting… we even won, on urban no less.
Think my next firefight challenge will be to only use random req cards.

I think your logic may be flawed in assuming it’s mathematical. I have it on good authority that Frankie watches every player play every match and assigns them a KDA based on where their Spartan falls on the “spicy meter.”
