As soon as you have completed the necessary game update ( there is talk of about 9 GB of additional data to download) and you will have started GTA Online, a short video will present you the new location of Los Santos, or the nightclub called Music Locker. Located below the Diamond Casino, and accessible from the rear of the Diamond Casino, the Music Locker will be your first stop to start preparing for the Cayo Perico Heist.
Once the short cinematic is over introductory and having finally arrived in your GTA Online session, in fact, you will receive a message from Miguel Madrazo, the son of the Mexican criminal Martin Madrazo, who will tell you he wants to meet you right inside the new nightclub. Then go to the Music Locker, pay the ticket and join Miguel inside the private room on the lower level, where you will meet him and that of Dave, a weird man who will be part of the story of the heist.
After the classic dialogue between the different characters introduced with this new update, you will find that the first step to design the very rich heist is to recover an old Russian submarine. To do this, once you leave the restaurant, you will have to access the Warstock Cache and Carry website, and buy the submarine that Miguel has told you about, spending a considerable sum of more than 2 million dollars. Once you have made the purchase, you will be contacted by Miguel, and you will finally be ready to start planning the different phases of the plan for the Cayo Perico heist.
The Cayo Perico Heist update for GTA Online includes lots of new features, including weapons, vehicles and 250 new songs for the many radio stations in and around Los Santos.
