6. Zombies!
Remember Red Dead Redemption? And the Zombie DLC/Expansion Pack? That game was pretty tasty, as was the zombie Downloadable Content. Many suggest they should do the same with their latest edition of Grand Theft Auto, though, others think differently. Unfortunately, I don't see this happening. But, then again, Rockstar and gaming as a whole has developed a lot in the past few years, so if Rockstar were to develop a Zombie DLC it could end up being incredible! An open-world zombie slaying/survival game. Just imagine. If Rockstar were to give it a proper go, I am sure it would make for a mouth-drooling expansion to their GTA Franchise.
