The Duggans have taken over management of the Diamond Casino & Resort, with all the money that GTA Online players are spending on penthouses and gambling fattening their wallets. Not to worry though, the latest DLC — The Diamond Casino Heist — is here to set things straight.
Despite your help during the Diamond DLC storyline, Tao Cheng has lost ownership of the Diamond, Los Santos' top (and apparently only) casino. Georgina Cheng takes the reins and contacts some of the best professional thieves in the city — that's you — as well as criminal mastermind Lester Crest to even the score. The plan? Rob the Diamond's vault.

The first step in such an ambitious heist is planning and you'll need a secure location to brainstorm. This is where the new DLC's property comes in — the Arcade. Your Arcade business will be a legitimate venture, but also a front for your HQ. You can stock up with 12 different kinds of games to attract clientele and there are a number of upgrades available for you to increase the income of the Arcade.
The twelve games cover a wide range of different genres and styles and are all fully playable. In case playing GTA Online isn't enough, you can now play a game while you play a game. The games include Badlands Revenge 2, a bombastic action game, three installments of Race and Chase, Nazar Speaks Fortune Teller, which is a reference to Red Dead Online, and many more.
