Woo! I love left 4 dead! Its the best zombie shooter i have ever played,i love how it makes you rely on your teammates,and though there are only 4 levels,this game has MUCH replay value because of how every single game you play is different. Also there is the fun versus mode where u get to play as the special infected,and have a chance to OWN as a tank!
That's all i have to say for now...
oh,my favorite character is Francis! Either that or zoey,since everyone will be nicer to you when your zoey=)

There actually are 16 levels if you are in campaign. There are 4 sets of levels:
No Mercy, Death Toll, Dead Air, and Blood Harvest. In Versus, they only have Blood Harvest and No Mercy.
Oh, and my favorite is Bill.
