It looks like a large-scale fan addon for Fallout 4 will be released very soon. The Fallout London team is waiting for the result of testing the build from the GOG store in order to release their project there.
Let us remind you that the mod was supposed to be released on April 23, but Bethesda unexpectedly announced the release of a next-gen update for Fallout 4. The developers had to postpone the release of the fan-made add-on due to fears that the patch could break the programs necessary for Fallout London to work.
The authors explained that due to the scale of the mod, a decision was made to release it on GOG, and not on a regular mod site. In addition, Fallout London will receive its own installer. The release date of the addon will be announced later.
By the way, recently the developers of the Fallout 2 remake demonstrated the updated design of Pip-Boy.
