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 a 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 take a picture of a specific Stockade with black livery. This can be at either at Murrieta Heights under the overpasses or in the tunnel at 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 taking the picture. 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. Regardless of their approach, the guards will be alerted as soon as an image of the plate is sent to Lester. The player then has to pick up the Gruppe Sechs outfits from the identified Stockade. 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 white and black one. Grab a pic of the plate on the rear of the truck and send it 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 sending an image of the number plate.

"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.
