Al Capone is a mythical character in Grand Theft Auto: Vice City. Al Capone was the most vicious, ruthless, deadliest, and dangerous crime figure in the world during his era and regime.
The paramount criminal importance of Al Capone has led Rockstar to include a large amount of substance references in relation to the mobster. Alphonse Capone "Scarface", built his criminal empire in Chicago and Cicero, Illinois, in 1920's. In 1928, he has moved, with his wife Mae and son Albert "Sonny", to 93 Palm Avenue (built by brewer Clarence Busch), Miami, Florida. Unlike Sonny Forelli, Sonny Capone didn't choose a life of crime.
In GTA III, there is a liquor store in Red Light District named "Big Als Liquor", Big Al was one of the names for Al Capone and Al Capone was a famous gangster in the Prohibition Era, in which selling and distributing liquor was illegal.
GTA Vice City
FBI who investigated Capone largely appear in Vice City, most notably after getting five stars. The predecessor of the FBI was a group of Special Agents called the Bureau of Investigation (BOI) created on July 26, 1908, for the Department of Justice headed by Attorney General Charles Bonaparte. It had a vast history of accomplishments in combating crime. Under Director J. Edgar Hoover, it had Al Capone investigated beginning in 1929, and gathered evidence of his Chicago racketeering, bribing of prison officials, determined the falsehood of his claim to post-pone an appearance before the Federal Grand Jury due to poor health, etc. It became known as the Federal Bureau of Investigation in 1935. "Scarface" a movie which Vice City is largely inspired by, is based on Al Capone's rise and downfall, connecting Al Capone's myth. Vice City also features references to "The Untouchables" a film about Al Capone's fall, which directed by the same director who directed "Scarface". Tommy's mansion also looks somewhat similar to Capone's in the movie. Capone also had a mansion in Miami, whom Vice City is based on. The structure of the houses on Starfish Island is conception-ally identical to Capone's house However, despite the large amount of references and indications, the myth is termed as unlikely due to the absence of Al Capone as a physically existing character.
There is a furniture shop named "Al's Furniture" The store could be a parody of Al Capone, who was in fact the owner of a furniture store and used it as a smokescreen for his illegal activities.
A DLC for GTA Online named St. Valentine's Day Massacre features multiple references, firstly the name and overall theme of the DLC is a reference to the Saint Valentine's Day Massacre on February 14, 1929, led by Al Capone, a car by the name of Albany Roosevelt is named after the president Franklin D. Roosevelt, who helped to minimize gang activity in the early 1930s and is speculated to have used Al Capone's custom Cadillac (on which the in-game vehicle is inspired on). However there are no references pictures or easter eggs in the original game.
