this game is super cool. fighting against hordes and more hordes of zombies, with the occasional boss zombie. is great.
versus mode is awesome, playing as zombie is awesome. sometimes you even get to be a tank. this in my mind is the best part of left 4 dead.
the graphics are pretty good. the animation of the zombies are super awezome. they all look pretty realistic, or the way i imagine a zombie fast like guy will move.
all in all its a great game, but i have experienced laggy servers, and if your teamates are stupid, it will really ruin the game. i've met stupid people like people who run infront of you, and people who shoots you, even if you stand still!!! friendly fire is mega annoying.
