Fallout 4 expansion Far Harbor released last week, and became Bethesda’s largest ever piece of DLC.
“The scale of this project is a land area that is just a bit smaller than Fallout 3, but more quests and locations than Fallout 4’s Far Harbor DLC,” reads the description.
According to VG24/7, Fallout Cascadia will be a mod which takes players to Seattle a few decades after the events of the main game.
