Rooks

The Rooks are a gang who operate in the abandoned Brooklyn Bridge Station, and are led by El Rey.

In-game
The Rooks are a small gang who deal in illegal drug and arms trade. None of the people who live in the underground tunnels seem to hold the Rooks in high regard, and a drug dealer called Rock tells JC, that they're a bunch of amateurs trying to play criminals.

They are involved in a quest, where El Ray asks JC to kill Rock for getting in the way of their businesses. If the player kills Rock, El rey will give him a LAM. Alternatively the player can kill all of the male Rooks members, and El Rey will offer JC the LAM as a sign of peace. The rooks are only encountered in the mole people station.

Trivia

 * The name Rooks might come from a species of birds in the crow family, or from the rook chess pieces (also known as "castles").
