Step-by-Step Walkthrough

1

Gather Your Crew

Start by assembling a team of reliable players. A good crew can make or break your heist. Aim for a balance of skills; you’ll need a hacker, a driver, and muscle to handle security.

Communicate with your team to ensure everyone knows their role during the heist.

Pro tip: Consider using players with higher skills for better success rates.

2

Choose Your Approach Method

There are three main approaches: Silent & Sneaky, The Big Con, and Aggressive. Each has its own set of prep missions and challenges.

Silent & Sneaky is ideal for a stealthy playstyle, while Aggressive is for those who prefer action. The Big Con allows for a more disguised entry.

Pro tip: Discuss with your crew which approach you feel most comfortable executing.

3

Complete Prep Missions

Before the heist, you must complete various prep missions to gather necessary equipment and intel. These include stealing vehicles, hacking devices, and scoping the casino.

Each prep mission should be tackled strategically; some may require stealth, while others may need brute force.

Pro tip: Focus on completing the prep missions related to your chosen approach.

4

Plan the Heist

Once all prep missions are complete, gather at the planning board to finalize your heist strategy. Make sure everyone understands their role and the escape plan.

Select the optimal entry point based on your approach, and ensure your getaway vehicle is ready.

Pro tip: Run through the heist plan with your team one last time before starting.

5

Execute the Heist

On the day of the heist, stay calm and stick to your plan. Communication is key—keep your team updated and adapt as necessary to unexpected situations.

Focus on your objectives and remember to watch for security guards to avoid alarming them.

Pro tip: Use your weapons wisely if things go south; avoid unnecessary firefights.

6

Make Your Escape

After securing the loot, escape the casino using the planned route. Follow your getaway driver’s instructions and avoid police if possible.

Utilize the getaway vehicle prepared during the planning phase to ensure a smooth exit.

Pro tip: Plan an alternate route in case of police roadblocks.

Tips & Tricks

  • Always communicate with your team during the heist.
  • Practice the heist with a crew to gain familiarity with the layout.
  • Upgrade your characters' skills before attempting the heist.
  • Choose a reliable getaway vehicle for a quick escape.

What About the Vault?

The vault is the main target during the heist. Make sure your hacker is skilled enough to bypass security quickly. The more time you have in the vault, the more loot you can grab.

Keep an eye on the timer to ensure you don’t get trapped as the guards start to respond.

Common Mistakes

One of the biggest mistakes players make is not communicating effectively during the heist. Always keep your team informed of any changes or challenges.

Another mistake is underestimating the importance of prep missions. Skipping them can lead to a high risk of failure during the main heist.
