The mod’s gameplay starts in 2237, between the events of the first and the second games and 50 years prior to Fallout 4’s main story taking place. Unlike the previous games in the series, the new mod is set outside the United States, presenting a novel environment, new post-war cultures and original factions, and the exploration of the influence of the Resource Wars on Britain.
The mod is a DLC-sized expansion for Bethesda’s Fallout 4, requiring the base game and all of the DLC to be installed. The expansion can be downloaded on GOG for free and is compatible with the Steam version of Fallout 4, with the team noting that they currently don’t plan on releasing the mod for consoles.
