Was going to nitpick the thumbnail, but I've decided I can't be bothered. Nothing in it feels "next gen", and stuff like "npc with metal detector" is something that npcs in V already do, just with other objects. Its not like the npc is actually programmed to look for buried treasure. It'll just be aimlessly wandering around, which I suppose technically is what people with metal detectors do.
Also, It's a fucking trailer. None of this was in-game. There is zero guarantee that just because they did something in a trailer, they'll do it in-game. Do they not remember Watch Dogs?
I just really hate these videos that exist solely for clicks/views and to milk something for every drop they can.
