One of the more fun DLC's for Fallout 3 was The Pitt and for Fallout 76, we're heading back there. In September, you'll be exploring more than Appalachia as The Pitt will open up for exploration.
The area's got a very orange red-ish hue to it I have to say. But the style sure definitely looks like it. You got those creepy ghouls that come charging at you and the architecture is a lot more industrial than Appalachia.
The Pitt will be the next major update to Fallout 76 coming September of 2022.
