In order to survive the zombie apocalypse, you will need many items before doing so: medikits, pain pills, flashlights, molotoves, pipe bombs, gasoline, propane tanks, and guns.Without these items, you will never survive.That goes the same for the incredibly addictive game 'Left 4 Dead'. In the game, you encounter zombies, hordes, witches, hunters, smokers, and tanks.The tank that I am referring to does not involve the army.The tank is basically a giant brute who looks like he used to be an ordinary man before he injected himself with tons of steroids.In this game, surviving the zombie apocalypse is pure fun.You'll be playing for hours and hours non-stop.Surviving the apocalypse hasn't been this much fun in a long time.
