Oh how high society frowns upon you! If you happen to be an Xbox LIVE Silver Member that enjoys decapitating zombies when you aren’t drowning kittens in your bathtub, you know that the Left 4 Dead 2 demo wasn’t available to you last week. Well, put the kitten down and power up your 360. Valve’s zombie fest sequel is waiting and your clogged tub drain will thank you.
