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.
