This guide details the Akula prep mission for Act 1 of the Doomsday Heist in GTA Online. Learn the recommended approach to infiltrate Fort Zancudo, download the critical flight data, and secure the Akula stealth helicopter for your operations.
For this prep mission, we highly recommend you get either a Buzzard or an Oppressor Mark II (if you have one). Also, make sure you have plenty of snacks and armour.
You need to go to Fort Zancudo and head inside of a control tower. Before you enter the control tower, just make sure you park your Buzzard/Oppressor Mark II right outside the door since you will need it later.
Once you head inside, go to the top floor and download the flight data in order to reveal the location of the Akula helicopter. During the hacking process, you will be detected and need to head back downstairs and out the same way you came in from. Just take it easy, first kill the guards and then move forward. Keep clearing and moving, and then head out the same door you entered the control tower from. Your Buzzard/Oppressor Mark II is now your quick getaway vehicle.
