"I have been planning out my zombie apocalypse strategy since I was in 8th grade. I have all my plans written out, know exactly where to go when the sh*t hits the fan and am confident that I will survive the coming apocalypse.
Even though I know I am ready for the downfall of humanity, I still play lots of zombie games just to stay on my toes. Other than teaching you to stay with a group, Left 4 Dead does a horrible job at teaching you defend yourself against zombies. As golden-silver mocked on his deviantART, the things Left 4 Dead shows you just wouldn't work in real life. I know because I'm a Zombologist."
