Heist Prep: Gruppe Sechs Gear Part 2

"The old Gruppe Sechs con... why do I love saying that? Well, if you're keeping count, we still need outfits, security passes, and the plate of an armored car, which is on the casino's roster. I've got the location of where Gruppe Sechs store their trucks. Get over there and snap an image of the right plate, so we can copy it."

- Lester's briefing.

Gruppe Sechs Gear Part 2 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. The player must have completed Gruppe Sechs Gear Part 1 in order to play this mission. Completing this mission allows players to use the Gruppe Sechs entrance disguise in the The Big Con Approach.

Overview
Lester informs the player that they still need outfits, security passes, and fake plates for their Stockade, so they have to go to a Stockade storage area to get their supplies. This can be in locations such as Murrieta Heights or Ginger Street in Little Seoul. Once there, however, the player will discover that Thornton Duggan's security team are around the area, requiring them to sneak around and not get caught. If they do get caught, all security workers in the area become hostile, requiring the player to fight them off, giving them a two-star wanted level. After losing their wanted level and delivering both outfits, the mission is complete.

Lester Dialogue
"Shit... looks like Duggan's security team are there. Must be discussing the next shipment. Keep your head down and quietly make your way to the casino's Stockade... it's the black and white one. Grab a pic of the plate on the rear of the truck send if over to me."

- After arriving at the location.

"Uh oh... you've been made. Maybe they aren't as stupid as they look, too bad for them. You'll need to wipe them out. No witnesses."

- After discovering the Stockade is locked.

"Tidy work, now grab the bags of equipment from the back of the armored car and make a break for it. Good luck."

- After killing all security team members.
