Vinnie Gognitti plays chief roles in both Max Payne and Max Payne 2. In the first game, he works for the Punchinello family and is hosting a mob war against Vladimir Lem.
Vinnie's background is fairly unknown in the Max Payne universe. He is a fan of the TV Show, The Adventures of Captain Baseball Bat Boy, and is childish for his age despite his position in the mob society. He is fairly clever, but also very cowardly-Max comments that Vinnie has "the brains but lack[s] the balls for the job [of running the Mafia]". Vinnie was known for taking out his frustrations on underaged call girls. As of the beginning of Max Payne, he is a financial manager for the Mafia and their V dealings; he also oversees contracts with hired killers, keeps an eye on Lupino, his boss, and other activities. Vinnie is high up in the Mafia as can be seen by his attire and large numbers of bodyguards.
In Max Payne, Vinnie works for the Punchinello crime family. He has a hatred for both Max Payne and Vladimir Lem.
In Max Payne 2, He is Vladimir Lem's scapegoat for everything that is going on with The Cleaners, framed as a criminal mastermind, wiping out his competition on the black market, when in reality, that is what Vlad is doing. Vinnie later gets trapped inside a Captain Baseball Bat Boy suit wired to a bomb and must get Payne's help if he is to live much longer. See Dearest Of All My Friends for more details.
