Starting the Doomsday Heist

In order to start The Doomsday Heist, you will need to buy a Facility. A Facility is needed in order to setup the heist acts and carry out all the necessary missions. There are a total of nine facilities to choose from with the cheapest facility costing $1,250,000 (located at Paleto Bay) and the most expensive one costing $2,950,000 at Land Act Reservoir. You can buy a facility from Maze Bank Foreclosures. Whichever facility you choose is completely dependent on your budget and how much you can afford. You will be able to carry out the doomsday heist whether it's from the cheapest or the most expensive facility.

Once you've bought a facility, Lester will call you to set up the heist. At first you will only be able to play through the Act in the order of 1 through to 3. After the completion of Act 3, you can replay any one of the acts in any order.

Setup Costs

Each act has its own setup cost which are:

Act	Setup Cost
Act 1 — The Data Breaches	$25,000
Act 2 — The Bogdan Problem	$25,000
Act 3 — The Doomsday Scenario	$25,000

This Act 1 guide series will walk you through all the preparation and setup missions of Act 1. Each setup mission has either one or two prep missions. After the completion of the prep missions, you can do the setup mission and after the completion of all the setup missions, you can finally carry out the heist itself.

You can do the prep missions solo, but the setup missions and the finale have to be carried out with a minimum of 2 players or else you won't be able to do the mission. Although, you can do the prep missions solo, it is highly recommended that you carry out the prep missions with at least one friend, as it will be much faster.
