Rockstar claims there will be more ways to set-up, prep, and explore missions than in previous heists there will be multiple paths of approach to the end objective, different security measures to consider, and in-mission choices that will need to be made on the fly. This heist will be a little more down to earth, tasking a group of four players to break into the vault at the Diamond Casino and take down the Duggan family, which took over the successful business via nefarious means. The last heist was related to a doomsday bunker, and was released two years ago. Heists in GTA Online are a set of lucrative missions that are tougher than your average job, but have a payout to match. Rockstar has announced a follow-up is coming to the Diamond Casino: a new heist coming in December. The last big content update for GTA Online introduced the Diamond Casino, a new zone where players can gamble, purchase a luxurious penthouse, and accept new missions from a new cast of characters.
