You can do this mission, either way, be sneaky and stealth everyone to death or be loud and rain down hellfire upon your foes. Understandably nobody wants to sell it to Avery as he’s a d**k, but his nephew doesn’t have the cash and the only way he can get it is if someone shuffles his uncle off this mortal coil. Cheng’s uncle has told them to sell the place as he’s tired of all the bad publicity that’s coming from the wake of bodies that you’re leaving behind you. And being the final casino mission, it’s a doozy. If you’ve managed to make it this far without dying or just throwing a fit and vowing never to play GTA Online again, then you’ll be glad to know that Cashing Out is the final casino mission.
