GTA Online Doomsday Scenario guide: An overview of the Act 3 of The Doomsday Heist
The Doomsday Scenario is the third Act of The Doomsday Heist in GTA Online. Rockstar divided the entire gameplay into three acts and each one has several numbers of prep missions, setup missions, and a finale. Therefore, you must complete them all in a serial order to get to Act 3 - The Doomsday Scenario.
Act 3 is again divided into six prep missions, five setup missions, and a finale. The GTA Online Doomsday Scenario guide advises players to be fully prepared before engaging in the gameplay.
Another important thing to note is that while the prep missions of The Doomsday Heist can be played solo, you will need at least one more partner for setup missions and the finale. Therefore, it is recommended to tie up with a trustworthy and/or skilled player. The prep and setup missions are also fairly complex. Having a partner to help will make the missions easier.
Here are all the prep and setup missions before reaching the finale (The Doomsday Scenario):
- Prep 1 - Marked Cash
- Prep 2 - Recon
- Setup 1 - Rescue Agent 14
- Prep 3 - Chernobog
- Setup 2 - Escort ULP
- Prep 4 - Flight Path
- Setup 3 - Barrage
- Prep 5 - Test Site Intel
- Setup 4 - Khanjali
- Prep 6 - Onboard Computer
- Setup 5 - Air Defenses

A brief overview of the Setup: Escort ULP missions from The Doomsday Scenario in GTA Online
The Setup: Escort ULP part is divided into the following two missions:
- Prep 3 - Chernobog
- Setup 2 - Escort ULP
In the Chernobog mission, GTA Online Doomsday Scenario guide readers must steal an HVY Chernobog from an area guarded by Merryweather. While the mission sounds easy, Merryweather guards will not let you take their property that easily. So, it is better to go prepared with enough weapons, ammo, and snacks.
The following are the possible locations where the HVY Chernobog may spawn:
- El Burro Heights
- Elysian Island
- Outside of the Fort Zancudo
- Grand Senora Desert
- Grapeseed
- Los Santos International Airport
- Murrieta Heights
- Paleto Bay
- Terminal
In the Escort ULP mission, you will first have to recover the HVY Chernobog from Cliffford Mercenaries and then protect Agent ULP in his escape. The latter can be seen flying a Nagasaki Havok helicopter while being chased by enemies. You can use the Chernobog’s missiles to take down the enemies. The process will continue till Agent ULP reaches the destination near the Grand Senora Desert.

Once these things are destroyed, you must deliver the stolen HVY Barrage to a drop-off point in Grapeseed.

A brief overview of the Setup: Khanjali missions from The Doomsday Scenario in GTA Online
The Setup: Khanjali part is divided into the following two missions:
- Prep 5 - Test Site Intel
- Setup 4 - Khanjali
The Test Site Intel mission is easy as you just have to break into a designated house and steal a laptop. However, guards are deployed both inside and outside the property. The GTA Online Doomsday Scenario guide advises you to take a stealthy approach to keep the stealing process smooth. Keep away from guards' visions and take them out with silencer-fitted weapons.
Once the laptop is found, deliver it to your Facility to complete the mission. The following are the possible locations of the designated house:
- Bridge Street
- Didion Drive
- Imagination Court
- Ineseno Road
- Kimble Hill Drive
- Mirror Park Boulevard
- Nikola Avenue
- North Sheldon Avenue
- Procopio Drive
- South Mo Milton Drive
In the Khanjali setup mission, you have to infiltrate the Thomson Scrapyard and kill all the enemies. After that, you must steal the TM-02 Khanjali tank and deliver it to the drop-off point. While Avon's mercenaries will try to stop you, you can use the tank’s weapons to easily take them out.

A brief overview of the Prep: Onboard Computer missions from The Doomsday Scenario in GTA Online
The Prep: Onboard Computer part is divided into the following two missions:
- Prep 6 - Onboard Computer
- Setup 5 - Air Defenses
Before starting this part, the GTA Online Doomsday Scenario guide advises you to level up your flying skills (if not already) as both missions take place in the air. In the Onboard Computer mission, you must take down a cruising Mammoth Hydra jet to steal a frequency module.
Once the fighter jet is down (most likely to get submerged into the Alamo Sea or Pacific Ocean), recover the module from the cockpit and deliver it to your Facility. During this process, a Nagasaki Buzzard Attack Chopper may spawn to kill you.
In the next mission, you must use a custom-made Volatol bomber plane to destroy Avon Hertz’s Surface-to-Air Missiles placed in various locations on top of Mount Chiliad. This mission is particularly tough as the Volatol plane is heavy and difficult to maneuver. Moreover, there are no homing missiles onboard. As a result, you must manually aim and destroy the targets using carpet bombs and remote turrets.
The GTA Online Doomsday Scenario guide readers must practice complex aircraft maneuvering techniques beforehand so that they can easily dodge the peaks of Mount Chiliad. While crashing into the mountain may not destroy the Volatol, you will lose momentum and may not be able to take off, if you get stuck.
By finishing all the Surface-to-Air Missiles, you will complete all the setup and prep missions of Act 3 of The Doomsday Heist.
A brief overview of The Doomsday Scenario final mission in GTA Online
The Doomsday Scenario is the final mission of Act 3 where you will have to fight with Avon Hertz and Cliffford. Since the former is an evil tech genius, he will send his army of automatic robots to fight you. Therefore, the GTA Online Doomsday Scenario guide advises you to fully replenish your ammo, health, armor, and snacks before the mission.
The following are the main objectives of The Doomsday Scenario final mission in Grand Theft Auto Online:
- Acquire either the Barrage or the Khanjali tank from Grapeseed.
- Enter the tunnel under Mount Chiliad through the secret passage.
- Destroy all the supplies and the enemies that spawn on the path.
- After a certain point, you won’t be able to take the vehicle further. Get on foot and head towards the control center. Kill all the enemies (including Juggernauts) on the path.
- Find the servers and hack them.
- Kill all Avon's goons and head to the top floor.
- Go to the Orbital Canon and destroy all the mobile cloud servers.
- Avon Hertz will escape through the Silo. Go towards the Lab Exit gate, equip a Jetpack, and follow him in the air.
- Kill Avon Hertz using the homing missiles in the Jetpack.
- Deliver the Jetpack to the Galileo Observatory.
Here are some pro tips for GTA Online Doomsday Scenario guide readers:
- Opt for the Khanjali tank instead of the Barrage.
- At the dead-end for vehicles, use the tank to kill nearby enemies.
- Use Miniguns to destroy Juggernauts.
- Since the soldiers are robots, use headshots to kill them faster.
After this, Lester Crest will thank you for the job and you will be rewarded with $1,800,000 (Normal mode) or $2,250,000 (Hard mode).
