Little Jacob is a Jamaican arms dealer from Dukes, and one of Niko's many associates.
He talks with a thick heavy Jamaican accent, and will provide discounted weapons to Niko for maintaining a good friendship.
He runs a failing taxi business in a converted industrial garage in Broker.
If you maintain a good relationship with Roman during the game, eventually he will provide a free taxi service for Niko.
Without a doubt, GTA 6 will blow us away, that is almost a guarantee. Then that defines the missions; you’re doing different things in LA than in New York or Miami.
