Blow Your Cover is the second Grand Theft Auto IV mission provided by Elizabeta Torres. Niko is introduced to Playboy X and Johnny Klebitz, as well as the SMG. This is the same mission as The Lost and Damned Buyer's Market. The same basic events occur in TLAD except from Johnny's perspective instead of Niko's.

• Elizabeta Torres asks Niko to accompany Playboy and Johnny to oversee a drug deal.
  
• Grab a vehicle that can accommodate Playboy. Sometimes his yellow Patriot is readily available.
• Proceed to the building in Broker.
• Pick up the shotgun under the stairs.
• Follow Playboy X to the third floor.
• Walk over to Johnny to trigger a cutscene.
• Enter the room with the two undercover cops with Johnny and Playboy.
• One of the cops repeatedly asks: "Are you carrying the stuff?" 
• Johnny tries to suddenly call off the deal.
• Immediately the two cops begin to scream to "Freeze."
• Johnny takes out the ambushing NOOSE team before heading downstairs to take the cops out and make his getaway.
• Take out the remaining cops.
• Return to the stairs.
• Take out the FIB officers.
• Climb the stairs to the roof, with Playboy taking up the rear.
• Take cover on the roof.
• Take out any remaining FIB men.
• Two FIB guys will come up the fire escape.
• Take them out as well.
• Go after Playboy down the fire escape.
• Take out the cops on the stairs.
• Head through the door to get back to the street to unlock Algonquin. Algonquin is accessible via the Broker Bridge, Algonquin Bridge, East Borough Bridge, and the Northwood Heights Bridge. There is still a terrorist threat in place for Alderney, so it is still not accessible.
• Lose your wanted level.
• Take Playboy to his Algonquin penthouse.
• When the mission is finished, Roman calls to let Niko know that he has purchased a new taxi depot with the proceeds from the fire insurance.
• Not only is the taxi service available for use, but the cabs have been upgraded from the old, black Esperanto taxis to black Cavalcades. 
• Completion of the mission unlocks Deconstruction for Beginners and The Puerto Rican Connection.
