How to Start and Complete The Bogdan Problem in GTA Online

Go to the Stromberg / Find the contact (Submarine Team)

Once you’ve started up the mission, take any car and drive to the Stromberg which is marked on your map. After you’ve acquired the Stromberg, enter the water and activate submarine mode by pressing [Right D-Pad], then approach the submarine to be automatically taken inside.

Upon entering the submarine, follow the path to the end whilst taking out the enemies, then take the stairs down to the next floor. Work your way through this floor and go down another level, then take a right and follow the path ahead to find the contact locked up.

(1 of 3) Once you're inside the Submarine, take out the enemies

Aim your gun at the contact and shoot around him to get him to give the information, then go back up to the Control Room and take a picture of the Intel Table via the Snapmatic App. Finally, plug Clifford into the Intel Table and watch the cutscene, then afterwards swim to land so the other team can pick you up.

Go to the Avenger / Take out incoming enemies (Air Support)

Once you’ve started up the mission, take any car and drive to the Avenger which is marked on your map. After you’ve acquired the Avenger, fly above the submarine which is marked on your map, then open up the Interaction Menu and choose Avenger Services followed by Engage Autopilot.

Press [Right D-Pad] to get into the Avenger’s Hold, then take control of the turrets by interacting with one of the multiple computers. Simply, destroy any incoming enemies until your teammate has exited the Submarine, then destroy the remaining helicopters before picking them up at the beach. Finally, take the Avenger to the Hangar at Los Santos Airport to bring this mission to a close.
