Heist Prep: Duggan Shipments

"Okay, okay, it is time to even out the odds a little. Duggan wants his guards armed to their big buck teeth, but we can cut off their supply. He's got a bunch of weapons and equipment shipments coming into the city. Get out there and destroy as many as you can."

- Lester's briefing.

Duggan Shipments is an optional prep mission featured in Grand Theft Auto Online as part of the The Diamond Casino Heist update. It is a freeroam mission needed to progress The Diamond Casino Heist. Completing this setup reduces the firepower and armor that guards have inside the Casino during the heist.

Overview
Lester informs the player that there are multiple shipments of supplies and weapons being delivered to the city by Thornton Duggan for his guards at the Casino, and it's the player's job to take them out. There are 10 targets scattered throughout San Andreas. There are ground shipments inside Stockades, air shipments inside SuperVolitos with a protective helicopter alongside, and sea shipments inside Dinghies.

The player has 10 minutes to destroy as many shipments as possible. They do not have to destroy all 10 shipments to make an impact on the heist, but there are levels of weakness reached after a certain number are destroyed. The guards' weakness increase on the third, sixth, and tenth destroyed shipment.

Lester's Dialogue
"Boom, nice! The more of these shipments you can find and destroy, the less they can use to find and destroy you. You get that? You see what I, uh... Alright, vamos!"

- After destroying the first shipment.

"Doing good so far. You're gonna feel the impact on their security in ther."

- After destroying the third shipment.

"Oh yea, baby... we're really weakening their position."

- After destroying the sixth shipment.

"Total wipeout. Casino security's really gonna be left holding their dicks after this. This heist'll be a cake walk."

- After destroying the final shipment.

"Too bad for them!"

"Ya got it!"

"Package destroyed."

"Kapow!"

"I love explosions."

"Nice work. That could've been the one they got you with."
