The Diamond Casino Heist is one of the most lucrative and thrilling missions in GTA Online, allowing players to execute a high-stakes robbery at the Diamond Casino. Here’s a detailed guide on how to plan and execute the heist successfully.

Preparation
- Acquire a Kosatka Submarine: First, players need to purchase the Kosatka submarine, which serves as the base of operations for the heist. This can be acquired through the Warstock Cache & Carry website.
- Gather a Crew: Assemble a team of up to four players. Each member should have specific roles to maximize efficiency during the heist.
- Heist Planning: After acquiring the Kosatka, players should begin the planning phase. This involves selecting the approach, gathering intel, and choosing the equipment needed for the heist.
Approach Options
The heist can be approached in three different ways:
- The Silent & Sneaky Approach: Focuses on stealth, requiring players to avoid detection. Essential equipment includes silenced weapons, disguises, and hacking tools.
- The Aggressive Approach: Involves direct confrontation with security. Players will need heavy weaponry and armor to survive the onslaught.
- The Big Con Approach: A mix of stealth and aggression, where players use disguises to infiltrate the casino. This requires a significant amount of preparation and coordination.
Planning the Heist
- Gathering Intel: Players must complete a series of prep missions to gather intel on the casino’s layout, security measures, and potential escape routes. This information is crucial for a successful heist.
- Equipment and Vehicles: Depending on the chosen approach, players will need to acquire specific equipment. For instance, if going in guns blazing, armored vehicles and heavy weaponry are essential. Conversely, stealth requires hacking tools and disguises.
