Zombies are freaking terrifying. They aren't real obviously...but they're still terrifying. How do you actually define what a zombie is though? It's hardly a definitive term are they fast? Slow? Do they have to rise out of the ground or can they simply be an infection? For this list, I chose to define zombies by the classic 'Romero' horrors humans that have died or been infected (but still resemble something that is dead) and are now reanimated, driven solely by their need for flesh. This excludes several games that would undoubtedly make this list, notably Resident Evil 4 (an all-time favourite) and The Last Of Us (please don't hate me) which both feature a parasitic infection, creating zombie-esque enemies rather than actual zombies. You may disagree with that evaluation (and please, feel free to discuss it in the comments) but without further ado, here are ten of the best zombie games of all-time, including one bonus game which needed mentioning.
