In honor of the anniversary, an update has been released for Fallout 4, and the Anniversary Edition has been introduced. The developers have resolved a long-standing issue with the VATS system.
From now on, an honest calculation of hit percentages will be performed:
VATS hit chance is now consistent across all platforms and no longer erroneously bottoms out at 0% or displays incorrect values. Targeting enemies through walls without the "Penetrator" perk is no longer possible.
The authors of Fallout 4 are also adding content from the Creation Club to the game: a variety of community mods, including those in the style of other Bethesda franchises.
Tale of the Beast Hunter has also been added to the game — you can try on a new costume, take a special "revolver-shotgun," and "bring a piece of Mojave to the Commonwealth with the 'Bar' — a unique new home for players, taken as if from the Strip."
