GTA 5 Diamond Casino Heist Aggressive Prep Missions

Here, we will take a look at all the important prep missions you need to complete for the Aggressive approach and how to do them. you can do all these missions by yourself or with friends. Of course, it will be easier if you have someone to help you

Support Crew

Gunman

Normally, most players would choose to hire an expert level gunman because this approach will be full of actions. That is a big mistake!

Instead, go hire KARL ABOLAJI, who will only charge for a 5% cut.

As for your loadout, the shotgun loadout will be better than the revolver loadout. You will also get an SMG, which you will be using the most.

Driver

You don't have to use the getaway vehicle to escape because you can just get a pedestrian-car. But you still have to choose a driver.

If you don't use the getaway vehicle, choose the driver who demands the least, which is KARIM DENZ.

If you DO use the getaway vehicle, choose SULTAN CLASSIC.

Hacker

This is the most important role in the heist. Hackers will interrupt the system to give you more time to get into the vault before the alarm goes off.

This is why you should spend as much as possible on the hacker. The elite hacker AVI SCHWARTZMAN is the best option if you have unlocked him. Avi will get 10% of the cut and you will have 3:30 minutes in the vault.

The default expert hacker is PAIGE HARRIS, who will get 9% of the final cut and you will have 30:15 minutes. He is a fine option if you don't want to unlock Avi.

Hacking Device

You have to get the hack device from one in two locations, the FIB building or N.O.O.S.E headquarters.

FIB building:

You will need to get a FIB agent pass to enter the building. You will be asked to go to a location to skill the agents to get the pass and escape from the police.
Park your car in front of the FIB building so you can run away easily.
When you are in the building, stay out of sight because the agents and guards might recognize you.
Use the elevator to go to the upper floor and use your phone to find the device.
Now get outside of the building. The agents will recognize you once you are near the exit so be prepare.
Get in your car in front of the building and lose the police to bring the device back to the Arcade.

N.O.O.S.E headquarters

You will need to go to Davis City Hall to kill the corrupt agent to take his key card.
Go to the N.O.O.S.E headquarters and park your car right in front of the building.
Find the device using your phone while avoiding the sights of the guards.
When you exit the building you will get 3 stars wanted level and get chased by the police.

GTA 5 Diamond Casino Heist Aggressive General Prep Work

There are 2 mandatory General Prep missions, which are Vault Keycards and Duggan Shipment. You can just skip the rest.

Patrol Routes mission is not mandatory but it will let you see the location of guards during the finale so you should do it as well. It is up to you because you will be pretty much just gun blazing in any way.

Vault Keycards

You will be given one in two missions to get the Vault Keycards. One mission will require you to hijack a prison bus to impersonate a prison guard. In the prison, go to a tower and take out the guards to get the Vault Keycards.

The other missions require you to go to 2 different locations to take down the guard and get the Vault Keycards. One guard is drunk on the street while the other guard will be in a motel. Use a suppressed weapon or a melee weapon to avoid the police.

You can also go rambo into the prison to get the Vault Keycards but it will be super difficult with the snipers inside the prison.

Duggan Shipments

This mission is super important if you choo the Aggressive approach. This mission requires you to destroy 10 shipments across the city. These shipments are quite far away from each other so having a friend to help you will be the best. You only have 10 minutes for this mission so it is quite hard to do if you do it alone.

By completing this mission, the guard in the finale will be really weak with low armor, bad aim, and low health.

Since you will be gunfighting the guards all the way through the Aggressive approach, this mission will make everything much easier.

Patrol Routes (Optional)

The Patrol Routes will show the positions of the guard in the finale, which is more useful for The Big Con approach and the Silent & Sneaky approach. It is still quite useful so it is totally up to you.

This mission requires you to find a specific card and take a picture of what is in the trunk of that car. The location of this car will change every time but it will be the same car model with a gray or black color. You can sneak in or kill all the guards to get to the car, but make sure you don't accidentally destroy it.

GTA 5 Diamond Casino Heist Aggressive Approach Specific Preps

You need to complete all the approach specific prep missions along with the mandatory prep missions. But if you are an experienced player with max armor and health already then you can skip the reinforced armor mission.

Here all the approach specific prep missions you need to complete.

Thermal Charges

This mission is simple. Just go to the location the mission requires, kill the guards and find the Thermal Charges in the warehouse, which is in a wooden crate. Note that there will be a lot of guards there. Bring the Thermal Charges back to the Arcade.

Vault Explosives

This is the hardest prep mission so I recommend having a friend do it with you or otherwise it will take a lot of time. You need to go to Alamo Sea to search the plane wreckage for vault explosives. There will be a lot of Merryweather soldiers there.

You need to get some rebreathers and put them on before starting the mission. Go to the locations and kill all the guards and dive to find the vault explosives. Head back to the Arcade to deliver the vault explosives. Whenever you get the crates, there will be Merryweather helicopters chasing you down so be sure to have a getaway vehicle.

Boring Machine

You don't have to do this mission but it will make your finale much easier and faster. The Boring Machine mission allows you to get to the casino vault easily by putting explosives on the wall which leads to the vault security lobby are and go to the vault directly.

To get the Boring Machine, you need to go to a construction site. Take out all the construction workers and guards there, which should be easy. Get into the truck with the machine on it and run away. There will be cops chasing you but you can lose them easily by calling Lester.

When you are free, go to the sewer and leave the Boring Machine there.

GTA 5 Diamond Casino Heist Aggressive Finale

Final Prep Board

On the Final Prep Board, you need to choose your entrance, exit point, your buyer, clean vehicle, and gunman decoy.

Entrance: SEWERS
Exit point: STAFF LOBBY
Buyer: IT is best to choose a high-level buyer for the most cash.

It is not necessary to pick a clean vehicle, and gunman decoy.

Heist Finale

Let's start the heist. Head to the sewer tunnels. There is a door in the tunnel which will lead you to the wall to the vault security lobby.

Go through the door and then plant your explosives on the mark on the wall on the mark there. A cutscene will start, in which the wall is blown open, followed by you and your buddy going through it and the debris fall down blocking the way.

Get inside, kill all the guards. It should be easy if you have done the Duggan Shipment prep mission. Just take your time to kill them one by one.

Go to the mantrap entrance and swipe the keycard with your friend to head to the vault. Plant explosives o the vault and use your phone to call the 'Detonate Bomb' contact. Get inside and loot everything as fast as possible. Use the thermal charges to open locked doors.

Leave when the timer hits 30 seconds, no matter what you are doing, and go to the exit. Swipe the keycard with your friend again to open the entrance to the mantrap. When you get to the vault security lobby, there will be a lot of guards. Take them out and head to the elevator to go to the staff lobby floor.

When the elevator opens, there will be a guard standing outside with a shotgun so be prepared to fight immediately. Get out of the elevator, and turns right twice, going toward 2 doors. Kill the guards there and go through the 2 doors. Turn left twice to go to a long hall that leads to the staff lobby.

There will be some guards along the hall. At the end of the hall is a double door that leads directly to the staff lobby. Kill all the guards in the lobby and head for the exit, through the metal detector.

Outside the lobby is a racetrack. Run on the right side of the track to the end, where the racetrack descends down towards your right. Jump over the fence to get out to the street to get a pedestrian car.

The cops will be chasing you. Go to the same sewer tunnels you started and wait until the cops are gone. Keep going through the tunnel to the other end. Once you are outside of the tunnel, make your way to the buyer, but don't go near the casino. When you get to the buyer, the heist ends.
