I watched the skylight before the alarms did — two guards moving like a single shadow, one wrong step away from everything going sideways. You and I had twenty minutes to turn a museum into a meticulously planned job. I’ll walk you through the prep so you don’t learn the hard way.
I’ve run these runs, read the patch notes from Rockstar Games, and watched strategy creators like DarkViperAU test each angle. This guide speaks in plain steps: what’s required, what’s optional, and how to finish each mission without wasting time. The planning board is a chessboard of risks; treat each move like it costs you both cash and reputation.
On the planning board, five columns stare back at you — how many prep work missions are there in the GTA Online Kortz Center Heist?
After you scope the Kortz Center, the planning board opens up with five prep categories. You only need at least one item from each non-equipment column; optional tasks are truly optional but they change the fight. Count them and you’ll see 17 distinct missions in total:
Infiltration Gear
- Staff Key Card
- Tactical Equipment
- Alpha Mail Disguise
- Hazmat Suit
Unmarked Weapons
- Street Loadout
- Security Loadout
- Military Loadout
Getaway Vehicle
- Manchez
- Armored Caracara
- Annihilator Stealth
Equipment
- Access Code
- Hacking Device
Optional Prep Work
- Guard Shipments
- Guard Routes
- Glass Cutter
- Power Drills
- EMP Charges
How many prep work missions are there in the Kortz Center Heist?
Seventeen missions total, split across the five categories above. Pick one method per required category, stack the optional tasks you want, and you’ll shape the day-of fight.
The map marker sits quiet — how to complete required prep work missions in the Kortz Center Heist
Choose your loadout on the board and Raf feeds you the intel. Below I ran the Staff Key Card, Street Loadout, and Manchez paths so you can copy the fastest routes I used.
How do I complete the required prep work missions?
Infiltration Gear — Staff Key Card
Raf points you to a hacker den in Vespucci. Expect a fight on arrival — bring armor and a Terrorbyte if you’ve one. Clear the place, kill the final hacker, grab the keycard cloner, and plant it outside the Kortz staffroom. Leave the area to receive your copied Staff Key Card.
Unmarked Weapons — Street Loadout
Raf traces a weapons ring to Mirror Park. Fight through the salvage yard, reach the repair shop, and open the locker by entering the password RAPID. Wipe the CCTV before you leave — you’ll be chased by the mob, but your mansion or any safe garage will break the pursuit.
Getaway Vehicle — Manchez
Manchez requires a dash into a Cocaine Lockup, a forced entry at Mission Row, and stealing the LSPD Garage keycard from the Captain’s office. Grab a bike, lose the cops, and deliver to your mansion. The Manchez is fast and nimble — use it if you want speed over armor.
Equipment — Access Code and Hacking Device
The game forces both of these on you. They’re small runs with big payoffs.
Access Code
Steal a drone from Del Perro, pilot it into the security firm, short the control panels, and download the access code from the terminals. Overcharge and blow the backup server so the firm can’t roll the code back.
Hacking Device
Interrupt an IAA handoff in Chamberlain Hills, take the IAA keycard, then swan into the facility. Use the keycard, open the blast door, clear the room, and grab the hacking device near the monitors. Exit through maintenance tunnels and deliver it back to your mansion.
The rooftop radio tower gives you answers — how to complete optional prep work missions in the Kortz Center Heist
Optional runs let you shave guards’ firepower and snag secondary targets. They make the heist smoother, but aren’t mandatory.
How do I complete the optional prep work missions?
Guard Shipments
Raf marks a weapons warehouse. Tear the shipments, hack the laptop to find the other vans, and destroy all three transport vans. Fewer guns for the museum guards = less trouble when you move on the vault.
Guard Routes
Find the tracker in a cruiser trunk, climb the Kortz rooftop, and plant it on the radio tower beside the skylight. You’ll see guard patrols during the heist and time your windows precisely.
Glass Cutter
Upload the OG (Prix Luxury AI Concierges) to KnoWay’s servers to reveal the cutter’s location. Hit the gang safe house, clear it, and grab the cutter so you can take secondary glass-locked targets during the heist.
Power Drills
Grab the drills at the construction site Raf marks. Stealth or guns — up to you — then deliver them to the mansion. Drills let you open vault lockboxes on the run.
EMP Charges
Breach the Mobile Operations Center, steal the EMP charges, jump into the Bravado Rumpo Custom, and drive them to the Kortz Center. EMPs shut down cameras and electronics on demand — they’re a strong equalizer.
Scope-out stage can reveal many of these optional targets. If you tick them off during scope, you’ll save time on the prep board and have fewer things to manage the night of the heist.
I’ve watched teams fail because they treated the prep as optional checklist items rather than tactical options. The Kortz skylight is a goldfish bowl and the guards are the water — decide whether you’re fishing with a net or a spoon. If Rockstar updates the heist mechanics, which mission shifts first: the glass targets or the EMPs?
