The Faustin Family was a Russian Mafia family in Liberty City and the second most powerful Russian family in the city after the Petrovic Family. They play a prominent role in Grand Theft Auto IV<, which results in all leading members of the Faustin Family being killed by Niko Bellic.
The Faustin Bratva, is a large family of Russian Mafia members, who seem to run in both Dukes and Broker. The family is headed by Pakhan Mikhail Faustin, an erratic and paranoid cocaine addict who lives in a mansion with his estranged wife and rebellious teenage daughter who was going out with one of the Lost gang. It would seem Faustin is a member of the Bratski Krug, or Circle of Brothers, a Russian version of the Italian-American Commission. Broker is run by one of the family's Brigadiers, Vladimir "Vlad" Glebov, a Russian loan-shark operating out of "Comrades" until he is executed by Niko Bellic.
Mikhail's orders for numerous hits on people for trivial matters draws unwanted attention from the law and upsets his partner, Dimitri Rascalov, who is angry that Mikhail has stopped following the unspoken rules of organized crime. Another Mafia family, the Petrovic Family, almost wage a full-scale war on the Faustin family when Lenny Petrovic, Underboss son of Pakhan Kenny Petrovic, is murdered on orders from Mikhail. This is averted when Dimitri secretly strikes a deal with Pakhan Kenny Petrovic to use Niko to kill Mikhail. Dimitri then assumes control of the Faustin family with his new partner,Ray Bulgrain, Niko's old boss in the human trafficking ring to whom Niko, supposedly, owes money to. The Faustin family under Dimitri and Bulgarin's new leadership betrays Niko and attempts to kill him. They then set fire to Niko and Roman's apartment and taxi depot, running the cousins out of Broker and Dukes.
After the death of Mikhail Faustin, Dimitri went independant, the Faustin Bratva was no more, adverting to the Rascalov Bratva.
