Heist Prep: Firefighter Gear

Firefighter Gear 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 allows players to use the Firefighter exit disguise in the The Big Con Approach. There are two possible missions that can be given here.

Arsonists
"Walking outta the casino dressed as a firefighter is going to be a solid tactic... providing everything has gone to plan up to that point. Anyway. there's been an alert, some kids have been playing arsonists and the fire department has responded in force. Get down there and steal a fire truck."

- Lester's briefing.

Overview
Lester informs the player that the fire department has been called to a location to put out a fire caused by some kids. This location can be in places such as the Vinewood Hills or the Grand Senora Desert. Once the truck has been stolen, the player will receive a three-star wanted level. Once the wanted level has been lost and the truck is delivered to the Arcade, the mission is complete.

Lester Dialogue
"Your gunman will stash these outfits at the casino using the chutes in the hotel section. Not sure where they'll end up exactly... could be the laundry room or the waste disposal. But either way. that's where you'll grab 'em on the way out if you need 'em."

- While approaching the Arcade.

Fire Department
"There's something a bit icky about posing as emergency services, but... you know what? I'm an icky kinda guy. No one's gonna stop some firefighters from walking outta there when the alarms are going, and that is just what we wanna do. You'll need a fire truck, of course, and some equipment... luckily, there are a few stations in the area. Grab a truck and bring it back here."

- Lester's briefing.

Overview
Lester informs the player that they need to steal a fire truck from a fire station, which will have the equipment they need to exit the Casino. The player can go to a nearby fire station and steal one, but calling Emergency Services on their in-game cell phone and stealing the truck that arrives also counts.
