Setting the Stage: Preparing for the Heist

Before you can revel in the spoils of the Diamond Casino Heist, meticulous preparation is key. Begin by gathering a reliable crew of skilled individuals, each specializing in a specific role. Your team will consist of a hacker, a gunman, and a driver – each contributing crucial skills to the success of the operation.

Choosing Your Crew

  1. The Hacker: Opt for the best hacker available, as they play a pivotal role in bypassing security systems during the heist. Lester Crest will recommend hackers such as Paige Harris or Avi Schwartzman, each with varying levels of expertise. Invest in the best hacker your budget allows for a smoother execution.
  2. The Gunman: While skills on the field are essential, selecting a gunman also involves assessing their cut percentage. Strike a balance between competence and cost-effectiveness, choosing someone like Gustavo Mota or Packie McReary, who offer a good mix of skill and lower percentages.
  3. The Driver: A skilled driver ensures a swift escape from the crime scene. Drivers like Karim Denz or Eddie Toh are popular choices, offering a favorable balance between cost and competence. Your choice here can significantly impact the escape phase of the heist.

Scoping Out the Casino

To ensure your heist goes off without a hitch, invest time in carefully scoping out the Diamond Casino. Access the casino’s cameras through Lester, identifying key points of interest (POIs) such as vault contents, security room, and access points.

Planning the Heist

With your crew in place and the casino meticulously scouted, it’s time to plan the heist. Head back to your planning board in your arcade and initiate the setup missions.

Silent & Sneaky, The Big Con, or Aggressive?

  1. Silent & Sneaky: This approach emphasizes stealth and subterfuge. Invest in suppressors for your weapons and equip your crew with outfits that reduce detection. Use EMP devices to temporarily disable cameras and security systems. This method requires precision and a coordinated team.
  2. The Big Con: Blend in with the casino’s patrons by disguising yourselves as maintenance workers or other employees. This approach involves strategic social engineering and a meticulously crafted plan to navigate the casino unnoticed. Ensure your crew has the right outfits and covers to pull off the con successfully.
  3. Aggressive: If subtlety isn’t your style, go in guns blazing with the Aggressive approach. Arm your crew with heavy weaponry and plow through security, aiming for a swift exit. This method requires brute force and resilience but can lead to a faster completion time.

Equipment and Approaches

A. Hacking Devices

To hack into the vault during the heist, acquire the necessary hacking devices through a setup mission. The quality of your hacker will determine the time you have inside the vault. Utilize their skills to bypass security systems efficiently.

B. Entry Points and Disguises

Tailor your approach by selecting the most advantageous entry points and disguises. These choices influence your initial infiltration, affecting how smoothly you navigate the casino. A smart combination of entry points and disguises can significantly impact your success rate.

C. Vault Contents

The contents of the vault are crucial to your payday. After scoping out the casino, you’ll have the option to cancel the heist and restart the process to get a different vault content. Choose wisely, as certain contents yield higher payouts than others.

The Heist Execution

With preparations complete, it’s time to execute the heist. The success of your operation hinges on coordination, communication, and adaptability.

  3. Escape: Evade security forces and exit the casino using your chosen getaway vehicle. A well-executed exit ensures a clean getaway and a successful heist.

The Big Con

  1. Disguise: Blend in with casino staff or patrons using your chosen disguises. Utilize your crew’s cover identities to access restricted areas without raising suspicion.
  2. Vault Keycards: Acquire vault keycards during setup missions to bypass fingerprint scanners in the vault, minimizing the risk of detection.
  3. Escape: Maintain your cover during the escape, utilizing your chosen getaway vehicle to leave the casino inconspicuously.


  1. Assault: Enter the casino with guns blazing, overpowering security personnel. Move swiftly to the vault and drill into the safety deposit boxes.
  2. Combat Gear: Equip your crew with heavy weaponry and armor to withstand the casino’s security forces. Utilize snacks and body armor to stay resilient during the assault.
  3. Escape: Battle your way out of the casino, utilizing your getaway vehicle to make a speedy exit. Navigate through law enforcement and reach safety to secure your hard-earned loot.
