Best exit casino heist big con

Having been grinding these heists since they come out I've since completed all Elite Challenges and worked out the best ways to complete them all so far. Below is my guide and Top Tips for The Big Con.

Elite Challenge

First of all, when you do your scoping out of the vault contents, make sure it is Artwork. Having artwork is much quicker to bag, and will also make you able to run at full speed. You are unable to do this with Cash or Gold. If you do not get Artwork, simply quit the scoping out job from your phone and try again until you do.

Heist Crew
Gunman - Abolaji
Driver - Karim Denz
Hacker - Paige Harris - Gives you plenty of time to collect everything you need and means you only have to hack one fingerprint for each vault cage door (unless on Hard mode, then it's 2 hacks per gate)

Preps
Mandatory:
Unmarked Weapons - SMG Loadout - Guns are not important here
Getaway Vehicles - Sentinel Classic. Denz also has good locations for the getaway cars spawning.
Hacking Device
Gruppe Sechs 1
Gruppe Sechs 2

General Prep Work:
Vault Keycards - to save hacking each lock
Patrol Routes - so you can see where everyone is

Security Pass:
Level 1 & 2

Planning:
Disguise - Gruppe Sechs
Entrance - Security Tunnel
Exit - Staff Lobby
Exit Disguise - High Roller (you can only get this if you've collected all 52 cards from the Casino DLC. If you've not done this then do the NOOSE or Firefighter Prep).
Buyer: Any

DO NOT WASTE MONEY on Clean Car and Decoy.

Tactics:
This is by far the easiest heist to complete. After a while you should be able to get the Elite Challenge to High Buyer every single time.

- All yo have to do is walk (or jump when the game allows you) to the vault then raid it.
- After you've raided the vault, jump all the way out and head up the stairs.
- Watch for the first guard who usually patrols around the elevator and stairs. Once he's out of your way head right and wait for the next guard to walk past the door heading right. Creep up behind and knock him out. Head towards the laundry area and change into your disguise.
- Once disguised you can simply run out through the Staff Lobby exit without any problems.
- Change camera to first person. This will make you run faster.
- When outside, jump over the fence in front, and run as fast as you can to the corner of the racetrack to your right where your getaway vehicles will be. Again, change to first person camera to run faster.
- The next part relies on RnG. Sometimes your cars will be closer than others. Just get in whatever car comes to you first, be it a car off the street or your own.
If you selected the High Buyer then head towards the Mesa Police Station and climb the building to get in the helicopter. If you didn't, then just drive to your checkpoint and lose the cops around that area. Going deep into the sewers will generally just lose you time.

Timing:
The Elite Challenge timer starts when you get the small cutscene to enter the casino after swiping your keycards (then 35 seconds of black loading screen).
02:30 - Vault cutscene
06:20 - Swiped keypads to exit the vault
08:50 - Exit casino
15:00 - Complete

Below is a video of my 2-player team completing this with maximum payout and delivering to the High Buyer.

Big Money Guide

Gold, Gold, Gold, Gold, Gold. Scope out Gold as the vault contents.

Heist Crew
Gunman - Aboloji
Driver - Karim Denz
Hacker - Avi Schwartzman - Gives you plenty of time to collect everything you need and means you only have to hack one fingerprint for each vault cage door (unless on Hard mode, then it's 2 hacks per gate), as well as allowing extra time to drill for a few more goodies.

Unmarked Weapons - SMG Loadout
Getaway Vehicles - Sentinel Classic. Denz also has good locations for the getaway cars spawning.

Buyer: Any

DO NOT WASTE MONEY on Clean Car and Decoy.

Tactics:
- I recommend only having a 2-player team. This will maximise your payout. You're looking at around $1.3m for each player this way.
- Complete this on hard mode (when it has the skull on it) for a collective gain of $200k. If you can complete this in 15 mins for the Elite Challenge you'll also get another $100k bonus each.
- Choose High Buyer in heist setup.
- Same as Elite Challenge
- You can raid the smaller vault in the room upstairs but the guards are difficult to take out together.

As a team of two, we've pocketed $1.3m each doing it this way.
