Hey this suggestion is simple in my head dont know about how you will see it but here goes. when you spawn and you start a fresh game you often just run around not caring much for what happens UNTIL you bump into somebody 1 of 3 things happens 1 you get killed, 2 you kill them, but i often try for the third option and that's teaming up, i try my best to signal im a friendly and stuff and we tag along for a while but we lose sight of each other and bang they are gone. my suggestion is when you first bump into somebody and you want to "buddy up" or w/e you want to name it. the two people will shake hands and in this time will " become acquainted " doing so will allow you to notice that particular person more easily, so for example the friendly person you shook hands with will now glow a faint green hue around them. you even in the corner of your eye you can spot where your friend is. if you wanted to take this 1 step further you could then add a faint trail left but your companion so you can see which way they went. now this would be most helpful at night time so you can tell the difference between friend and zombie when you try to take that shot to save his life. Now i understand that this is heavily a realistic game that is why im asking for this to be implemented if i was to group with survivors in this scenario i would STUDY and i mean STUDY what cloths they were wearing the color of hair, shoe type anything i could so i would KNOW without doubt that , that person was indeed on my side. TL;DR cant tell difference between friend and foe after teaming up with someone, give visual que to denote who has teamed up with you, shake hand animation to signify agreement.
