This guide will provide the best way to complete Cayo Perico Heist in Grand Theft Auto Online.
First, you will need to enter the heist from Kosatka, head upstairs, and kill the guard. After that, grab the key card if you find one.
Head down and wait for the juggernaut; once he arrives, take him down with four shots. You must use a shotgun only to kill him and then kill the guard standing on the balcony.
Destroy the camera near the fountain and head up to eliminate two more guards. After that, you will get the key card for sure. Destroy the camera on the wall and head upstairs to kill a guard.
Now you will be able to open all the locks using keycards. Bring your friends and steal everything from the offices and stores. The guards you have killed will never spawn again. You can also go to the compound and steal everything from there. It is how you can complete the heist by killing all hose guards and destroying the cameras.
