The Doomsday Heist/Preparations

Preparations (Preps for short) are side-missions featured in Grand Theft Auto Online as part of the Doomsday Heist update.

Overview
Preparations are side-missions given to owners of Facilities when they start the setup missions.

In order to progress the Dommsday Heists, players must obtain the necessary Heist Prep Equipment to unlock the setup mission, and the process repeats in order to complete the heist finale (or acts, in this case). The Heist Crew can complete these preps and setups in any order.

There are three ways for completing the preparations:
 * Initiating a Freemode Preparation.
 * Stealing the equipment from rival Heist Crews.
 * Purchasing the equipment directly (if available).

Freemode Preparation
Freemode Preparations are the standard way for acquiring the necessary equipment, which consist of free-mode tasks given to the crew to obtain it. Like Supplies and Air Freight Cargo missions, there is no specific way to progress the mission, as long as the required asset is obtained and delivered to the facility sucessfully.

Paramedic Equipment
The crew have to move to Mount Gordo, where a paramedic and an LSSD officer are responding on a car accident in Route 1. The crew have to take the Ambulance and lose the cops to retrieve the vehicle in the facility.

It unlocks the setup mission "Dead Courier".

Deluxos
The crew have to move to Dunstable Lane in Rockford Hills, where a security group are guarding Deluxo sports cars. The crew have to eliminate the head of security to find the key to the mansion's garage. Once inside, a small group will be found defending the target cars, so the crew have to eliminate them as well. Once acquired, the group have to take the vehicles to Los Santos Customs for a respray and plate change and then leaving it to deliver the vehicles to the facility.

It unlocks the setup mission "Setup: Signal Intercepts".

Akula
The crew have to go to Fort Zancudo with military clothing and limited access pass. They need to go at the base's control tower, eliminate the tower officer and download the flight data for the Akula stealth helicopter. The download sequence will alert the military, so the crew have to defend the player who is acquiring the data.

With the data, the crew have to move to Banning and take out the enemy group to steal the helicopter, lose the cops and delivering it to the facility.

Grand Theft Auto Online

 * The location of the "Paramedic Equipment" preparation appears to be the same as the "Crash Rescue" random event from Grand Theft Auto V, where Taliana Martinez was found and rescued.
