Your planning base

The Diamond Casino Heist uses the basement of an Arcade for planning. Rockstar's update notes place Arcades on Maze Bank Foreclosures.

Three approaches

  • Silent & Sneaky
  • The Big Con
  • Aggressive

Preparation missions depend on the selected approach. The planning process includes hiring support crew, with optional preparations providing additional equipment.

Big Con preparation checklist

This PS5 checklist covers an experienced Big Con / Gruppe Sechs / Artwork run with the Staff Lobby exit. Start with your Arcade, scoping, route choices and selected crew already available. Check the access conditions below before tracking your preparations.

Preparations can be completed solo; the finale needs a second player. Required work and optional tasks are shown separately. This checklist tracks readiness; it does not estimate earnings or completion time.

Watch the route

Use Fresh Gaming’s recorded run as a visual refresher: prep board at 1:53, finale choices at 2:33, and Staff Door escape at 7:12. The recording’s payout and timer are not used for an earnings forecast.

The checklist follows that run’s entry and exit choices. First-time unlocks, other approaches and a room-by-room beginner walkthrough need separate guidance.

Should you do Duggan Shipments?

Duggan Shipments is optional. Completing it weakens the guards' equipment for the finale. These PS5 tips help you decide whether to include it. Gibson Vasela's original walkthrough.

You can run this prep solo. With two pilots, divide the city and countryside targets between you. Partial destruction can still weaken security, so keep pursuing shipments if you miss one. Vasela's Duggan advice.

The mission gives you ten shipment targets and a ten-minute limit. Use an available Buzzard or missile-equipped Oppressor Mk II, check ammunition before starting, and focus on the marked shipment rather than its escort. Sajid's vehicle and target advice.

If you can already request a CEO Buzzard, it is another documented option: awesomefoot's Duggan run uses one, and Sajid's access explanation identifies the CEO Vehicles request option.
