Shows the relationship between all the starting mercs. The relationship effects mostly their moral; in some cases the mercs want more money or refuse to join the team.
Every merc has a different relationship to each other. If a merc is in a team with a person he likes, his moral will rise by 1. If he dislikes the person his moral will fall by 1, he wants more money or he refuses to join the team compleatly. I also made this guide into a short video, if you want to support me, otherwise you can just scroll down.
How I got the data
I simply went trying error, for around 7 hours, until I got every merc pared up with each other. I filled the result inside a chart:
black: The person itself
green: Both mercs like each other
red: Both mercs hate each other
blue: One merc likes the other
orange: One merc hates the other
