I've been wanting something like this myself for a while, and as I could not find one and could not find someone who made them, I created one myself.
This is made for the wonderful community in Sea of Thieves, and I know several of you have been looking for something like this.
I use my overlay with the fantastic kill counter made by https://www.twitch.tv/shockwavez3r0.
Enjoy!
