5. Stores Will Become Survival Tools
An interesting pastiche of the zombie film is for stores to offer a safe haven from the undead. From the iconic mall of Dawn of the Dead to the product placement haven in 28 Days Later, right down to the lighter fluid filled toy shop in zom-com Doghouse, store hideouts have always been a bizarre partner with the flesh eating apocalypse. Even Dead Rising's setting and Left 4 Dead 2's gun shop have continued this tradition. So it would be great for GTA's theoretical zombie mode to follow suit too. Zombie horde inches away from taking a bite out of your posterior? Dive into a store and funnel them in, buying ammo or candy (depending on your retail choice) when needed and creating a pretty cool, unscripted set piece in the process.
