A few months ago, Rockstar Games released a new update for GTA Online that finally unveiled the Diamond Casino. With rumors of GTA 6 swirling around the internet and Red Dead Redemption 2 online still in its early years, some fans believed Rockstar was set to slow down on adding any significant updates for GTA V’s multiplayer mode. Well, that’s not the case as the developer/publisher has just announced a brand-new heist for the game.

According to Rockstar Games, The Diamond Casino Heist will be the game’s biggest and most ambitious heist yet. Here’s an excerpt from the announcement mentioned above that breaks down what you’ll be doing in the heist:

The ability to replay the heist to uncover a different ending or a new crucial decision is certainly appealing, especially compared to the tamer early heists from GTA Online. It also sounds like preparation for The Diamond Casino Heist will be much more significant this time around. The development of GTA V’s campaign heists was critical to how the missions played out. You can go in loud and stupid or try to get things handled discreetly. Who you selected on your squad was also somewhat important. In several previous GTA Online heists, there was a disconnect in that regard. It seems that this will change with The Diamond Casino Heist.

Along with the new unpredictable heist, players will also be able to open up a retro Arcade business property as a front. There, you can practice specific tasks you’ll need to master for the heist while your business is booming upstairs (which totally sounds like something out of Ocean’s Eleven).

The Diamond Casino Heist will release December 12th, 2019.
