This page is a walkthrough for the Cayo Perico Heist Preparation Mission, Alkonost. It’ll navigate you through the necessary steps to successfully acquiring the Jet.
Go to Fort Zancudo / Search for the laptop
Once you’ve activated the mission via the planning board on the Submarine, either use the sub to fast travel closer to Fort Zancudo or simply drive there yourself. After you’ve arrived at your destination, enter the military base as you have clearance, then enter the Hangar which is marked on your map.
Upon entering the Hangar, take out a silenced weapon and take out the soldier on the stairs nearest to the door, then head up to the next level and walk across to the opposite side. Drop back down to the ground level and sneak into the rooms nearby.
Take out the enemies when they’re on looking, then approach the laptop and press [Right D-PAD] to initiate the hack. Upon completion, enter the Alkonost via the side door and press [R2/RT] to exit the Hangar. Finally, fly above the clouds so the police can’t find you, then deliver the jet to the Hangar Los Santos Airport to bring this mission to a close.
