This page is a walkthrough for The Doomsday Heist Setup Mission, Signal Intercepts. It’ll navigate you through the necessary steps to successfully hacking the Vans, Boat, and Plane.
Use the Deluxos to get close to multiple target vehicles and hack them to recover.
Go to a Deluxo / Hack a Target
Once you’ve started up the mission, take any car and follow the waypoint to the Deluxos you collected in the Deluxos mission earlier. After you’ve taken control of the Deluxo, you’ll see four marked vans on your map, so set a waypoint via the Quick GPS in the Interaction Menu.
As you approach it, bring up your phone and click the SecuroServ Hack App, then stick to the side of the van to avoid the enemy until you have 100%. Upon completion, use the missiles equipped on the Deluxo and destroy the van before proceeding to hack the remaining three.
Once all of the ground vehicles have been hacked and destroyed, make your way over to the water and press [Right D-Pad] to activate Hover Mode, then approach the four boats and hack them the same way you did the vans. Again you’ll be getting shot at, so circle the boat until completion, then destroy it.
Go to Los Santos International Airport / Hack the Plane
With all the ground and water vehicles hacked, travel over to Los Santos Airport to find one final task to hack a plane. To do this, stick the Deluxo in Hover Mode, then pull back on the left stick to begin flying. Stay above the plane to keep the hack progressing, then eventually you’ll start getting attacked by multiple helicopters.
Keep one member of the team near the plane to continue hacking, then use your homing rockets to take down the Helicopters before returning to the plane. Finally, destroy the plane once the hack is complete, then deliver the Deluxo’s to the drop off to bring this mission to a close.
