GTA Online Diamond Casino Heist: Silent and Sneaky Strategy Guide

If you’re gearing up for the Diamond Casino Heist, this GTA Online Silent and Sneaky guide is designed for you. As one of the most sought-after heist missions in the multiplayer segment of Grand Theft Auto V, Rockstar introduced it in December 2019, continuing the storyline of The Diamond Casino & Resort saga.

Though GTA allows you to tackle a heist in various ways, adopting a stealthy approach is highly recommended. This mission features a Silent and Sneaky route that significantly lowers risk while ensuring a successful outcome. This guide will outline the key aspects of this method, guide you through it, and share vital information to prepare you for the heist.

GTA Online Silent and Sneaky Guide: Introduction to the Basics

Before diving into the GTA Online Silent and Sneaky guide, it’s essential to understand how Rockstar Games designed the concluding segment of The Diamond Casino Heist. There are three approaches for the finale:

• Silent and Sneaky
• The Big Con
• Aggressive

Your primary objective is to infiltrate the casino vault and acquire the designated loot. Rockstar Games offers four distinct types of rewards inside the vault:

• Cash ~ $2.1 million
• Art ~ $2.3 million
• Gold ~ $2.5 million
• Diamonds ~ $3.2 million

Readers of the GTA Online Silent and Sneaky guide should be aware that Cash is the lowest-value and most frequent reward, while Diamonds represent the highest-value yet rarest loot. Regardless of the reward, any approach can be employed for this mission.

It’s crucial to note that, unlike the Cayo Perico Heist, The Diamond Casino Heist cannot be conducted solo. Rockstar Games mandates having at least one other player in your mission lobby to initiate it. Therefore, you should team up with fellow players in Grand Theft Auto Online to successfully complete The Diamond Casino Heist.

Now, let’s dive into the core components of the Silent and Sneaky approach for The Diamond Casino Heist.

Best Support Crew for the Silent and Sneaky Approach of The Diamond Casino Heist

Since this approach emphasizes stealth, a support crew isn’t strictly necessary during the mission. However, the mission host must choose a crew before commencing the heist. This is where many players who overlook the GTA Online Diamond Casino Heist Silent and Sneaky guides can make costly mistakes.

Each crew member comes with a specific cut, which will be deducted from your final reward. Picking random crew members can significantly reduce your payout. Therefore, the GTA Online Silent and Sneaky guide recommends selecting the following crew members:

• Gunman – Karl Abolaji
• Driver – Karim Denz
• Hacker – Paige Harris or Avi Schwartzman

The subsequent outlines detail the cut percentages and services provided by these crew members:

• Karl Abolaji (5%) – Micro SMG, Vintage Pistol, Stun Gun, and Knife OR Machine Pistol, Combat Pistol, Stun Gun, and Knife
• Karim Denz (5%) – Weeny Issi Classic, Maxwell Asbo, Dinka Blista Kanjo, or Übermacht Sentinel Classic
• Paige Harris (9%) – 3 minutes 25 seconds (undetected)
• Avi Schwartzman (10%) – 3 minutes 30 seconds (undetected)

Although a Gunman isn’t necessary, Karl Abolaji is the optimal choice due to his low cut. Ensure that you choose his second weapon loadout. Since the getaway vehicle is rarely utilized, it’s advisable to select Karim Denz with the Übermacht Sentinel Classic.

Selecting the Hacker is crucial for the Silent and Sneaky method, as they dictate how long you have for looting the vault. To unlock Avi Schwartzman for the heist, you need to destroy 50 Signal Jammers scattered across the game world. If time is tight, the GTA Online Silent and Sneaky guide recommends using Paige Harris instead, who can be unlocked after acquiring the Terrorbyte.

Essential Prep Work for The Diamond Casino Heist

Executing The Diamond Casino Heist involves completing various Preparatory steps prior to the main mission. While you can opt to perform all of them, the GTA Online Silent and Sneaky guide recommends focusing on these specific missions:

• Vault Keycards: You’ll need to acquire two keycards to access the mantrap within The Diamond Casino. Rockstar Games will assign you one of the following missions: Duggans’ Goons or Prison Guard. Your objective is to eliminate the target and retrieve the keycards from them.
• Vault Lasers: These tools are vital for efficiently drilling through the vault. Hence, readers of the GTA Online Silent and Sneaky guide should prioritize stealing this equipment from the Military.
• Nano Drones: Nano Drones allow you to eliminate various foes from a distance. Each player is provided their own Nano Drone, and this mission is essential. Consequently, the GTA Online Silent and Sneaky guide suggests stealing Nano Drone components from the Los Santos Police Department.
• Guard Patrol Routes: Search for a Felon GT located around Little Seoul, Pillbox Hill, or the Galileo Observatory. The trunk will hold a guard roster that you need to photograph, send to Lester Crest, and then exit the area to avoid alerts.
• Security Pass: This pass permits entry to different parts of The Diamond Casino without needing to hack the doors. Given that hacking consumes time, the GTA Online Silent and Sneaky guide emphasizes completing this mission.
• EMP Device: Although optional, the GTA Online Silent and Sneaky guide suggests undertaking this mission as it allows you to temporarily disable the power supply of The Diamond Casino. During this period, security cameras become inactive, and guards struggle to locate you.
• Infiltration Suits: If you carry out the EMP Device mission, the GTA Online Silent and Sneaky guide also recommends stealing Infiltration Suits from Fort Zancudo or the Humane Labs and Research establishment. These suits include night vision goggles that facilitate visibility in low light.

It’s important to stress that while the final mission involves two or more players, the Prep Work missions can be accomplished solo in Grand Theft Auto Online.

Final Setups for The Diamond Casino Heist Silent and Sneaky Approach

Before embarking on the final mission, Rockstar Games presents a setup board named Final Prep Board, where you select critical elements for the operation. While making your selections, the GTA 5 Casino Heist Silent and Sneaky guide recommends the following:

Entry Points

Rockstar Games offers four entry options to The Diamond Casino during the heist: Staff Lobby, Waste Disposal, Roof Terrace, and Helipad. The GTA Online Silent and Sneaky guide recommends selecting the Staff Lobby as your entry point. It provides the quickest access to the vault.

Exit Points

The exit points coincide with the entry points. Therefore, the GTA Online Silent and Sneaky guide advises choosing the Staff Lobby as your exit point without hesitation.

Buyer

Opt for the ‘High Level’ buyer consistently. They offer the maximum payout for your loot. However, keep in mind that these buyers are typically located far from the Casino, necessitating considerable travel.

Critical Tips for the Final Missions of The Diamond Casino Heist (Silent and Sneaky Approach)

Keep in mind that The Diamond Casino Heist heavily relies on RNG. As a result, you may encounter different enemies and environmental variables during each playthrough. While core mission elements (such as the loot and certain stationary guards) remain consistent, variables like patrolling guards and vehicle spawn points can vary significantly based on RNG.

For those following the GTA Online Silent and Sneaky guide, enter the casino through the Staff Lobby. Before advancing, ensure to scout for guards, security cameras, and metal detectors. The main Staff Lobby door contains two cameras that should be disabled using the Stun Gun.

However, be cautious not to destroy too many cameras, as this will trigger the security alarms and compromise your stealth. The GTA Online Silent and Sneaky guide urges you to navigate around as many cameras as possible without setting them off.

All guards and security cameras have visibility cones displayed on the minimap. Players are encouraged to observe these attentively before moving forward. If a guard or camera obstructs your path, eliminating them is advisable, given they haven’t been seen by others.

The objectives for The Diamond Casino Heist utilizing the Silent and Sneaky approach are as follows:

1. Enter the Casino.
2. Descend to the Basement.
3. Locate the mantrap door.
4. Utilize the Keycards to unlock the mantrap doors.
5. Pass through the mantrap to find the Vault door.
6. Drill the Vault door locks.
7. Collect the loot within the designated time frame.
8. Return to the Staff Lobby door using reverse tactics.
9. Evade law enforcement.
10. Deliver the loot to the buyers.

While these objectives appear straightforward, readers of the GTA Online Silent and Sneaky guide should remember that hidden obstacles lurk at every turn. First, alerting security doesn’t instantly fail the mission; rather, you and your team must confront the guards while proceeding towards your target.

Both Keycards and Vault Lasers require simultaneous operation by two players. Therefore, the GTA Online Silent and Sneaky guide emphasizes the need to establish clear communication with your team before the mission.

After entering the Vault, the Hacker will provide a limited timeframe to acquire the loot and exit. Delays may trigger the security system, flooding the chamber with poisonous gas, resulting in your demise.

Readers of the GTA 5 Casino Silent and Sneaky guide should also be aware that the security will be alerted even if you successfully collect the loot in time. At some point during the exit process, security will be notified of your heist and come to apprehend you. Even if you manage to dodge them, a five-star wanted level will be assigned.

Upon exiting the Casino, your objective becomes escaping law enforcement and the NOOSE team without being spotted. The selected getaway vehicles frequently appear near police checkpoints. Hence, the GTA Online Silent and Sneaky guide recommends steering clear of them and instead opting for an NPC vehicle.

Once you’ve secured a car, head toward the LS Storm Drain sewer entrance near the Casino. This underground route will assist you in evading your wanted status easily. After that, proceed to the buyer’s location to deliver the loot.

By adhering to the GTA Online Silent and Sneaky guide carefully, you can successfully complete the mission and secure your status as a millionaire in Los Santos.
