This community created mod rivals some DLC in size and scope.
Fallout London

Last year, a community made mod for Fallout 4 was revealed to the world. It is called Fallout London and is a mod that would looks to rival the size of many official expansions. It brings the post-apocalypse to England in the year 2237.

We haven't seen nor heard much about this mod for about a year now. Today, the team released over 18 minutes of gameplay footage, which can be found below. The footage includes the start of the game and some additional content from a bit further in.

No release date has been set yet for Fallout London, but you can keep up with the development at the official Fallout London website.
