I’m surprised this hasn’t been mentioned yet. Before the April patch, this was just an empty field (presumably for artillery tests) but now… It’s something else entirely.
There’s plenty of ammo to go around, along with a Magnus .44 revolver of high quality if you search a little, and signs of an attack but the main doors are sealed shut. The letters on the doors read “FOA 2”. And here I thought there was only one FOA facility. Anyone willing to speculate?
