This page is a walkthrough for the Cayo Perico Heist Preparation Mission, Stealth Annihilator. It’ll navigate you through the necessary steps to successfully acquiring the Chopper.
Destroy Anti-Aircraft Turrets / Steal the Stealth Helicopter
Once you’ve activated the mission via the planning board on the Submarine, then either use the sub to fast travel closer to the Merryweather HQ or simply drive there yourself. After you’ve arrived at your destination, take cover and clear out the enemies, then use Sticky Bombs to destroy the Anti-Aircraft Turrets.
Upon removing all the turrets, collect the Stealth Helicopter, then fly towards Los Santos International Airport whilst using the turrets on the Annihilator to destroy Merryweather Choppers along the way. Finally, park up the Annihilator at the marked Hangar to bring this mission to a close.
