A dedicated group of modders are collaborating to make a colossal Fallout 4 campaign set in Seattle.
Dubbed Fallout Cascadia, the giant mod aims to be “just a bit smaller than Fallout 3, but [with] more quests and locations than Fallout 4’s Far Harbor DLC.”
Fallout Cascadia will be a completely separate campaign from the main game, with its own storyline and everything.
Little is known about the plot other than it will be set several decades after Fallout 4.
