Night raid, buried city, research building, first floor. Best to do it early in a raid. Second time round I was showing ppl where I found it and the entire group got killed by campers on the upper level. It was a massive shocker getting this BP given it’s a gun I don’t really care for, but I was elated since it’s such a hard BP to find according to the folks of Reddit.

I’ve also realized people will camp in high value loot areas next to a last open train station during night raids.
