Mafia III follows the story of Lincoln Clay, a member of the Black Mob who is returning from the Vietnam war only to come back to a war zone. The Black Mob is betrayed by the Marcano Family run by Sal Marcano. Instead of laying down and letting the mafia have its way, Clay plans on rebuilding the Black Mob to be even bigger than it was before. Tired of oppression in the city of New Bordeaux, the new Black Mob will take down every single crime family and corrupt politician plaguing the people.
To help him, Clay has recruited three Underbosses including Vito Scaletta who fans will remember as the protagonist from the second Mafia game. He’s also trying to get back at the Marcano family who has been seizing too much territory and leaving him in the shadows. Clay and his Underbosses will stop at nothing until all organized crime in New Bordeaux belongs to them.
