Found something really cool yesterday while exploring the archipelago south of Vessian bunker (Archipelago Region).
Sorry, I should have taken screenshots / grabbed coordinates.
If you head directly south of Vessian bunker, staying on the hilltop, following the road, heading towards the lighthouse, you will come across a Bank truck with a bunch of locked containers inside.
On the roof of the bank truck there is a dead guy in jeans, leather jacket, and what looks like a costume face mask (the kind commonly worn by robbers in movies / TV) with a .44 revolver fallen beside either hand.
There is another corpse with similar clothes and two .44s on the ground near the truck.
In a ring around the bank truck are about a half dozen cop cars and a bunch of dead cops.
Grim, but a very cool detail, just one of many scattered throughout this beautifully detailed game!
