On the surface, Left 4 Dead 2 seems like the same game as the original L4D. The gameplay and setup and everything are awfully familiar. When you dig a little deeper, however, you find a game that is improved in just about every way. The presentation is better, the campaigns are better, there are more modes, and the new weapons make the gameplay quite a it deeper than it was before. Left 4 Dead 2 is a better game than the original and definitely worth a look.
