Yeah the great thing about the audio version is that you can just pop it on when you are in bed and then listen to it well you fall asleep. Just to let you know crazed gets much better as the thing goes on. 
Also what is with everyone using military grade weapons? Even with most soldiers being zombies that still is alot of zombies to fight.
Also looking for a CoGM i am going to admit i have not watched all of zombie land but i like the idea of a recent apocalypse rather then a old one due to no one being able to get a helicopter without some brilliant writing.
