Escuela of the Streets is the first Grand Theft Auto IV mission received from Manny Escuela. Manny tells Niko that he wants to clear the streets of known drug dealers, when he in fact wants to clear them for his own business. 

• Find yourself outside on the street at the end of the cutscene.
  
• Grab a car.
• Once in the car, Manny directs you to the known location of the North Holland Hustler drug dealers on Grand Boulevard.
• Follow the GPS to the location.
• Park behind the suspicious looking car and wait for him to drive away.
• Follow the dealer to his accomplices without letting him detect your presence, but being careful not to lose him.
• If Manny repeats that you are too close, back off a bit. If he warns you too many times, you automatically fail the mission.
• Follow the dealer when he pulls into the Sprunk warehouse in Bohan.
• Park behind the dealer's car for a cutscene.
• When it ends, Manny sends you in to take care of them.
• Exit the car and Manny leaves.
• Proceed to the warehouse entrance.
• Go around to the side of the building.
• Climb the fire escape of the building next door up to the roof.
• Cross the plank over to the roof of the warehouse
• Find the SMG on the roof. It is the most powerful in the game.
• Drop in the open skylight.
• Take out the enemy near the soda machine first.
• Take out the enemies that are close enough with auto-aim.
• Use the cover system by hiding behind the stacks of Redwood boxes to avoid enemy fire.
• Proceed towards enemies stealthily until you can take them all out.
• If you are running low on health, buy a can of Sprunk from the soda machine for a half refill of health.
• Once the area is clear, run through the warehouse and pick up any guns or cash laying about.
• Exit the warehouse.
• Wait for Manny and Jay, his camera guy, to pick you up.
• Receive a $1,000 reward for your trouble, and unlock Street Sweeper.
