This page of the guide covers the mission 'Don't Fuck With Dre', available within the 'The Contract' update for GTA Online.

Don't Fuck With Dre

The final mission of this DLC, you have a waypoint marking Johnny Gun's last known location. Head there and right next to the train tracks in the corner of the search area you'll find him and his gang. He'll make a getaway and you have to defeat all his henchmen. Upon doing so, you'll want to head to LSIA.

Once at the hangar at LSIA, you'll face heavy resistance. Therefore it is advised to purchase body armor at the start of the mission, and slowly progress through the hangar taking cover as much as possible. Clearing the whole hangar will reveal Johnny on a raised platform next to the biggest central plane. Shoot him and he'll fall down. Head up to him and pick him up to initiate a cutscene where Dre takes his revenge. With the cutscene over, he'll ask you to drive him to Pacific Bluffs Country Club, whilst treating you to a sample of one of his newest songs.

Upon arrival at the club, the final cutscene plays out where you and Dre exchange thanks and he boards his helicopter to leave Los Santos. You'll earn a hefty $1,000,000 for all your hard work from this mission alone! Congratulations on completing 'The Contract' DLC!
