Absolute MUST WATCH!! Left 4 Dead Opening Cinematic, over 4 minutes! AGH!

Okay, I read up some, and the one with the really long tongue is a mutated Infected - a Boss - called the Smoker.

Then the giant one toward the end is the Tank.

There's also the Boomer, the Hunter, and the Witch, but they didn't show in the opening cinematic.
