This is a major departure from the previous Fallout games, all of which had level caps. To our fans who’ve asked: Fallout 4 doesn’t end when the main story is over and there is no level cap. In fact, Fallout 4 doesn't have a level cap at all, said Bethesda: Fallout 4 players will be able to continue exploring the post-apocalyptic Commonwealth, and keep leveling up, after finishing the game's main story, developer Bethesda Game Studios announced today on Twitter.
