Controls are broken
Other than the controls being flawed, Left 4 Dead is a good game. If you can manage to get the hang of the controls, the game can probably be fun to play. Unfortunately, that probably won't happen
Graphics in Left 4 Dead aren't great, but they aren't that important anyway. If gameplay was good, i wouldn't care what the game looked like.
The game isn't really scary, zombies come rushing at you, but it's more intense than it is scary.
Listen I wanted to like Left 4 Dead, i really did, but the controls are just simply too flawed for the game to be any type of fun. If you think you might want this game, be sure to rent it or get it from Gamefly before you buy it, because you might end up disappointed like I was if you decide to buy it without renting.
