Fallout 4 has many interesting characters to meet across the Commonwealth, but one villain may be the key to immortality in the post-apocalyptic universe. Fallout 4 introduced many firsts for the franchise, the biggest being a change to more modern gameplay. These changes mainly included sprinting and improved gun mechanics. This allowed the franchise to appeal to a wider range of players who typically enjoy faster-paced games and improved over aspects of Fallout 3 and New Vegas.
