Shadow is the second and final Grand Theft Auto IV mission received from Rastafarian Little Jacob. Jacob has not been receiving what he feels are his share of profits from a local drug dealer. Jacob asks Niko to find out who the supplier is and to "take care" of them.

• Proceed to Jacob's apartment on Dillon Street in Schottler, Broker.
• Enter Jacob's apartment where Niko is immediately jumped by Badman and threatened with a boxcutter. After reassurance from Jacob, Niko is released.
• Jacob describes the local drug dealers who are making money without handing over Jacob's share of the profits.
• Badman asks that Niko go over to Wallkill Avenue in Fortside to follow the local dealer to his supplier. 
• Follow the dealer quietly as he proceeds to his supplier for additional drugs.
• It is best to follow quietly so the dealer does not suspect you. If the dealer escapes, or is injuried or killed, on the way to the supplier's apartment, the mission is failed.
• Once Niko arrives at the dealer's apartment, the door should be unlocked if Niko did not alert the dealer to his tail.
• If the door is unlocked, Niko can just enter. 
• If the dealer was alerted, the door will be locked and Niko will need to shoot the lock in order to open the door.
• Take out the three men inside the apartment.
• Call Jacob to tell him that the mission is complete.
• Successful completion earns $250 and unlocks Russian Revolution and Friendship with Little Jacob.
