Ok, so I tried this out a little I have a few findings
Family was least hostile to white name tags (Guards also wouldn't shoot until a family member did)
With Vtec a close second.
BB's shot on sight (The ones I could find)
Ironically I couldn't find any lawyers to test on and see if they were fooled at all
The sewers were very boring all alone, but I did make a friend. I also found it quite peaceful at one point.
I successfully removed and stored items on GATE exit grids, due to timer.
There were more friendly players than one that shot on sight. Surprisingly more than if I had one of the used colors
I helped a Family member fend off rad scorpions and a V-Tec farm some brahmin. I then placed everything I found at family base.
I died a total of 2 times in around 2 and a half hours, which is considerably less if I was my regular color and spent that time in core or around enemy gates, but of course I didn't encounter enough players for it to be tested properly.
and once there is a known "sewer rat" faction peoples attitudes may change for better or worse.
I think thats all, hope it helps in figuring something out sounds like a cool idea, I had fun for a couple of hours.
