From then on, whenever Niko calls Little Jacob for work, the latter will give him a location where his "product" needs to be delivered. The drugs are located in a car parked next to the Homebrew Cafe on the Broker-Dukes Expressway. You can use this vehicle or your own (you just have to get in to pick up the product) or you can simply call a taxi that will take you there instantly (which helps if you have to complete the delivery within a given time frame).
The deliveries take to you numerous locations in Broker and Dukes, and play out in a different order each time. They fall into the following categories:
- Timed: The buyer is waiting to deal and is getting nervous, the player must reach them and make the deal within a time limit.
- Stash: The player must stash the product in a secure location for the buyer to pick it up later. Typically, a rival gang knows about the stash point and ambushes the player when they make the drop, leading to a shootout. The player must kill all rival gang members to complete the mission.
- Deal: The player must meet with the buyers to make the deal. There is no time limit, but when the transaction is complete the police will show up and crash the party. The player must escape and lose their wanted level to complete the mission.
Every completed delivery pays $250 and increases Jacob's friendship by 1% and respect by 3%.
Note: The missions do not necessarily take place in this order
Autosilo Cerveza Heights
Your objective is to stash the package under a dumpster in Dukes, the same area where many of the TBoGT drug wars end, and also the first safehouse of Chinatown wars. After Niko stashes the package a rival gang will block him in with a car, and two gangsters will appear on the roof above Niko, and to complete the mission you must kill of the the rivals.
East Island City Tunnel
In this mission your objective is to meet the dealer in the tunnel in East Island City, under the East Borough Bridge. This mission is a timed one and you must reach the customer before they abandon the deal.
The delivery is also timed, and the customer is found in a tunnel under the Algonquin - Dukes Expressway, in Schotter. During the cutscene showing Niko handing over the package, you will plainly see a flying rat on one of the ceiling on the tunnel if you haven't yet killed it.
For this the customer is waiting in an auto repair garage in Beechwood City, at the intersection between Carson Street and the Broker - Dukes Expressway. To pass this mission you have to arrive before the customer abandons the deal.
The customers are found in an alley in Willis, the same one Little Jacob and Niko went to during the mission Concrete Jungle. You will meet three gang members, but once the deal starts the cops arrive and you will recieve a two star wanted level. To complete the mission you have to lose the cops.
This mission is another stash one, and you are required to stash the product in an alley in Meadow Hills. After you do this, a rival gang surrounds you with cars as well as being on foot. As always you must kill them all to complete your objective.
Meadows Park Festival Towers
For the delivery, Niko must stash the drugs under a dumpster across the road from Meadows Park, nearby to the McReary Residence. Four rivals will discover the stash point, and Niko has to wipe them all out.
Once the player has successfully completed ten deliveries, Jacob will send a text message saying the police are cracking down and there will be no more deliveries. Completing all ten deliveries will reward the player the Courier Service achievement. Your reward for finishing will be a Jamaican Huntley Sport with a different grille and exhaust from the normal ones.
