Liberty City

Brooklyn analog — Niko's borough through most of GTA IV.
Broker is one of the four boroughs of Liberty City in , and . It is the third largest borough next to Dukes and Algonquin.
It contains 12 out of the city's 65 neighborhoods. Its real-life archetype is . It is situated to the south of the borough of Dukes and connected to Algonquin by the Broker and Algonquin bridges.
Streets in Broker are named after Western-era cowboys and cowboy-related words (Cassidy Street, Deadwood Street, Earp Street, Hickcock Street, and Kid Street are some examples). Avenues in Broker are primarily named after Native North American tribes (Iroquois Ave, Mohawk Avenue, Onondaga Avenue, and Seneca Avenue are some examples).
Broker and Dukes are the only boroughs in the metropolitan area that share an island. Water separates all the other boroughs.
This is the borough in which the player begins GTA IV, in which Niko Bellic meets his cousin Roman Bellic, and GTA Chinatown Wars, in which Huang Lee escapes from a sunken car in BOABO, after which he goes to talk to Wu Lee about the loss of Yu Jian.
Broker's central business district is its Downtown neighborhood, which is a successful business district beside Outlook Park with tall buildings. Broker is still a deprived borough shown in other areas though, as it was from the beginning; around eastern Broker including Schottler, Firefly Projects, and Beechwood City there are many tramps and gang members along with a high crime rate fueled by an underground drug market. Likewise, some areas in Hove Beach can be dangerous too, for example there are many armed Russian gangsters walking around in the industrial part of Hove Beach as well as near Niko and Roman's apartment. Much of western Broker consists of safer, middle-class neighborhoods along with the busy downtown area.
According to the documentary A History of Liberty City on CNT, Broker is named after Sir William Broker III. He was the king's bastard son that was conceived by a milk maid.
