This guide covers locating and delivering the four Strombergs for Act 2 of the Doomsday Heist.
The first part of Prep 4 for The Bogdan Problem (Act 2 Doomsday Heist) involves acquiring the Strombergs. These vehicles are vital for the 'Submarine Recon' setup.
The fourth setup mission has two prep missions you need to complete before you can do it. In the first prep mission, you need to locate four Strombergs. The Strombergs will be on the move since they will be carried around by a truck. There will be six trucks and only four of them are the correct ones carrying the cars.
We recommend you get either a Buzzard or an Oppressor Mark II for this particular mission for easier travel. Although this mission is completely possible to complete solo, it is also highly recommended to have at least one friend with. Doing this mission solo will take you a long time to complete.
