Kortz Center Heist Setup: Best Mandatory Preps to Choose

There's required work that you'll need to do before the Kortz Center Heist finale, which includes choosing Infiltration Gear, Unmarked Weapons, the Getaway Vehicle, and the two pieces of Equipment. Here's what we'd recommend:

Prep Work

Type

Why It's Useful

Alpha Mail Disguise

Infiltration Gear

Alpha Mail Disguise lets you drive into the Loading Bay without guards getting suspicious, giving you the most direct backdoor access to the Kortz Center vault.

Street Loadout

Unmarked Weapons

The Street Loadout comes with a suppressed pistol, which is all you're going to need.

Annihilator Stealth

Getaway Vehicle

The Annihilator Stealth places a helicopter on the helipad above the Kortz Center Heist that can be used as a quick getaway to avoid the roads swarming with police and get to the finish line faster.

Access Code

Hacking Device

Equipment

These are non-optional, and you don't have a choice between other equipment, so you'll need these regardless to break into the vaults.

Alpha Mail Disguise Prep Mission

As soon as you enter the warehouse, take a right and kill the first guard blocking your path. Continue on the path and enter the lockers on the right, where you will find an Alpha Mail outfit to wear as a disguise. Unequip your weapons and head past the guards with your disguise to the office on the left to collect the Alpha Mail ID.

With the disguise and ID, you can collect the Alpha Mail van and leave the warehouse. Take the van to any Los Santos Customs to change the license plate, and then return the van to your mansion to complete this setup.

Street Loadout Prep Mission

This mission is very straightforward. Just enter the warehouse, kill the gang members inside, and find the keypad at the stairs. There's a hacking minigame where you have a few letters, and you just need to make the word (shuffle it into a decoder if you need to. Our word was "RAPID," so it was easy enough to figure out). Once you have the guns from inside the room, hack the CCTV and return to your mansion.

Annihilator Stealth Prep Mission

Annihilator Stealth Prep Mission

This mission can be quite difficult solo, but bring plenty of ammunition, and you'll be fine. You'll want Armor, Snacks, and explosives. Head to Fort Zancudo and head to the warehouse, which is marked with an A and a B. You need to look up at the warehouse doors and use RPGs and Homing Launchers to destroy the locks.

Now that both locks are destroyed, look around Fort Zancudo for a military truck with a flatbed lock that will allow you to collect the Annihilator Stealth Helicopter from within the warehouse. Once obtained, leave Fort Zancudo and evade the police while taking the vehicle to the Sandy Shores Airfield.

Annihilator Stealth Prep Mission (4)

Finally, use Right on the D-Pad to fly the Annihilator in stealth mode, which keeps you off the enemy radar. Evade the jets that are searching for you, and head to the destination marked on your map to deliver the vehicle and end the prep work.

Access Code Prep Mission

For this prep mission, you'll need to follow the objective to a container, where you will find a drone inside. When you take the drone, follow the marker to the nearby rooftop and deploy it with the Right D-Pad. You need to approach the security firm's rooftop and interact with the vent to enter.

Inside, fly toward the terminals and use R1 to scan them. If anyone is in your way, use L1 to shock them and knock them out. When you find the right terminal, remain in the vicinity to download the code, but if you are caught, you will have to do the hack again (I only needed to shock the guard on the walkway).

Now, head out of the room and hold Square to Detonate onto the rack of servers, and leave the area to complete the mission.

Hacking Device Prep Mission

Find and kill the corrupt agent and loot his body for his IAA key card. Raf will then tell you where to go next. Once inside the building, he tells you to go to, you can either explode the electricity panel or hack the computer, but I'd recommend hacking the computer as you just have to stand and wait for it to complete, whereas destroying the electricity panel causes a blackout.

Once you're inside, collect the hacking device from the main room and then follow the other side to the exit (it's behind the green array device). Now, exit the tunnels thanks to the van parked outside, and return to the surface where you can take the hacking device to the mansion.

Kortz Center Heist Setup: Best Optional Preps to Choose

There are 5 optional prep work to complete, but there are only 4 that are worth doing, and here's why:

Prep Work

Why It's Useful

Guard Shipments

Reduces the weapons and armor that the Kortz Center security guards will have during the heist.

Guard Routes

Allows you to see the positions of all security guards at the Kortz Center during the finale on the minimap.

Glass Cutter

Allows you to cut through the glass in certain display cases in the main gallery area to gain even more loot.

EMP Charges

Disables lights, cameras, and destroys CCTV footage, and unlocks a new area of the gallery and basement. It'll be dark, but guards won't see you, and you can loot in peace.

Power Drills is only worth doing in a 4-player heist lobby, but even then, it's better to just run the EMP Charges and loot the main exhibition gallery. Just remember to turn off the alarm before smashing the display cases!
