Doomsday Heist: Bogdan Problem Prep 4b - Torpedo ECU Collection

Collecting Torpedo ECUs is the second part of Prep 4 for The Bogdan Problem (Act 2 Doomsday Heist) in GTA Online, following the 'Strombergs Acquisition'.

In this prep mission you will need to assault an oil barge off the coast and get Electronic Control Units (ECUs) off of it. The barge will be highly guarded. You can either do it solo or with a friend. We recommend you have at least one friend for this mission as there are two units you need to bring back to the facility. If you decide to do it solo then you will need to re-visit the barge and get the second one as well.

It is best to use either a Buzzard or an Oppressor Mark II, these vehicles will make the mission much easier for you. If you go in a car then you will have to get to the barge using a jet ski, which will increase the chances of you getting shot at and dying. So, go in either a Buzzard or an Oppressor Mark II, and kill all the guards.

You will also get two enemy choppers, take them down as well. All these enemies can be easily taken out using the homing missiles on your Buzzard or Oppressor. Once you've taken them out, land and get the ECU and bring it back to the facility.

On your way back you will again have two enemy choppers chasing you. You can just ignore them and head straight to the facility. If you are doing the mission solo and return back to the other barge, you will notice two enemy choppers hovering over it. Take them out, collect the second unit and bring it back to the facility as well. This completes the second part of the fourth prep mission.

With the Torpedo ECUs secured, you have everything needed for the 'Submarine Recon' setup mission. Find all guides on our Bogdan Problem Hub.
