For me it’s the eyes, this build I tried to play slightly less lethal and have more of a neutral but morally correct approach. Not too much unnecessary conflict. Hence the green eyes.
But my first build is put together completely maximizing destruction, no stealth, whoever dies dies as long as I can complete the mission, picking the most aggressive dialogue options lol (unless it’s his friends panam, Judy, etc.) on him he has the reddish/orange version of the green eyes.
I’ve chosen the eyes to just symbolize my approach to the game overall.
