Different weather and different time. And the structures on the twitter-pic maybe indeed are there during one of these new procedual missions. So this screenshot could be out of the testing area.
“Dear Community,
We found some ruins today, but I think they were already there before the Machines took over. There was a military checkpoint set up, but the rust buckets had already overrun it. Luckily, there weren’t many of them left!”
I was this close before turning on the PS again to look, cause I was sure that I’ve seen this float, boat and boathouse before… Somewhere at Avern Lake.
“Dear Community,
Today, we took down one of the flying Machines for the first time!
It was a tough fight, but we won by hiding in a barn to avoid its shots. I don’t know what kind of wood these things are built out of, but I’m thankful it withstood the hail of bullets!”
