The team also offers a few quick tips for new players:
Before the game: HOOK UP YOUR MICROPHONE! Communication is important in L4D2. Make sure you can keep in contact with your teammates.
In Game: stay with your teammates. L4D2 is all about teamwork and leaving your dentist friend behind to go off on your own will only get you killed. It doesn't matter that you glow!
Post Game: Make friends. If you are having fun with a group, send them friend invites or join a common group.
There's not really much more to say, here's a free game for Christmas! Even if you already have it, be sure to tell all your friends who don't.
