People who live in a fantasy world where L4D is an expansion or not worth the full price and feel entitled to free things from Valve can shove it. The DLC will cost money, most likely $5-10, and those who won't pay, this isn't for you anyway. L4D isn't a series for you. Stop being delusional that you're entitled to things because you're one of the millions who buy quality Valve games and grow up. Even if you won't stop being delusional, all of Valve's content is more than worth what they charge, they need to start increasing prices to what they offer is worth or they may go bankrupt. Even if this game was considered an expansion pack it was worth the full price. I didn't think Giantbomb had people like this on their forums.
