After the
rumor of December on setting and plot of the next
Fallout , now new rumors come thank to the appearance of the game on IMDB, under the name
Fallout: Shadows of Boston . The page was promptly removed, perhaps an indication of the veracity of the data: before it was removed, visitors could however hear that the game is in production with output planned for 2017 and that the English voice actors include Ron Perlman, the voice of Three-Dog Erik Dellums and other actors that have in the past worked on Metal Gear Solid, Fallout 3 and Skyrim.
According to the page, the story of Fallout: Shadows of Boston would be co-written by Chris Avellone of Obsidian and Erik Caponi of 2 k Games. We have to wait to find out if everything is truth.
