He commands his personal army called the top dogs, a powerful group of mobster that are pure evil. Goodneighbors and Diamond City has been conquered by Top Dollar's forces. He call the shots now and the citizens of goodneighbors and diamond city are forced to work for the top dogs. Nothing goes on without his say.

You must gather your companions and find a way to destroy Top Dollar and his top dogs, the greatest threat the commonwealth has ever seen. After a miracle, the Sole Survivor and one of his companions managed to kill all the top dog invaders in diamond city and goodneighbors. Now you must journey to Top Dollar's HQ called the Tower of Sin and put a stop to this evil once and for all. It won't be easy as he has dozens upon dozens of top dog mobsters within the tower of sin.
