Doomsday Heist Act 1 Setup: Signal Intercepts Walkthrough

Welcome to the Signal Intercepts setup mission guide for Doomsday Heist Act 1 in GTA Online. This walkthrough explains how to effectively use the previously acquired Deluxos to hack multiple moving targets on land, sea, and eventually in the air, gathering crucial intelligence.

In this setup mission, you and your friends will need to get into the Deluxos and hack some targets. The first four targets are inside moving vans. Get close to them and hack the targets using the SecureServ app on your phone. You will see a yellow circle around the targets, that yellow circle represents the vicinity you need to be in for the hacking to work. After hacking, you need to destroy the vans. A tip when you're hacking the van is to stay in front of them in order to avoid getting shot at.

After hacking all four vans, you will need to hack four more targets — this time, on boats. The Deluxos have a hover mode feature which is unlocked when you get to the boats part of this mission. You simply need to go to the boats and hack the targets. A tip to avoid getting shot at from the boats is to circle around them while staying inside the yellow vicinity circle in order to hack. After hacking the targets, simply destroy the boats as well.

Finally, after hacking the targets in the boats, you will need to head over to the Los Santos International Airport and hack the target inside of an airplane. Yes, you guessed it — your Deluxos at this point will get a feature to fly and not just hover. Once you get the airport, the plane will take off and you must get closer and stay within its vicinity in order to hack the target. You will be attacked by some enemy choppers but you can hack and ask your friend to take care of the choppers or vice versa. Once you're done hacking, simply deliver the Deluxos to the drop off point and you are done with your second setup mission.

Successfully intercepting all signals and delivering the Deluxos marks the completion of this setup. Our Doomsday Heist Act 1 Hub has guides for all other missions in The Data Breaches.
