Fallout 4: Final Fronts

Fallout 4: Final Fronts, more commonly called Fallout 4 or Final Fronts, is a fan-made first- and third-person video game that is the sequel to Fallout: New Vegas. Fallout 4 uses many components from Fallout: New Vegas and Fallout 3, including controls and settings. Fallout 4 sees the return of factions, such as the Brotherhood of Steel and Enclave, but also many new factions, such as the Tribalized Brotherhood of Steel, Enclave Outcasts, the Illuminati, and the Phoenix Group.

Plot
Currently, the only information about the plot is that it includes a Brotherhood of Steel Paladin whose squad was killed during battle with Super Mutants, and he lost contact with the Brotherhood base in that area. While making his way back to the Brotherhood base, he picks up a radio signal coming from the ruins of New York City that is coming from a mysterious man named "Yuri", who tells him to follow the signal and meet him in the remains of New York City. He is left with a choice of whether or not to track the signal. He ultimately decides to follow it, and he begins the long journey to New York City.
