Oh man I hope these little comics become a thing because I love reading some ones like Critical Miss over on the Escapist.
Favourite zombie games I'd have to say are:
Dead Rising 2
L4D2
Dying Light (absolute fave currently)
Contagion (great for co-op/MP survival)
Nazi Zombie Army
Resident Evil 1-3/Code V/Outbreak 1-2
COD Nazis Zombies
That's about all I can think of from recent memory, will probably edit more as time goes on.
Step right up come on in, feel the buzz in your veins, I'm like an chemical electrical right into your brain and I'm the one who killed the Radio, soon you'll all see
So pay up motherfuckers you belong to "V"
