still very new to do game and I have below 10 hours of experience in it. So I may be lost at some point but this game seem fairly linear when it comes to the path to take. This Left 4 Dead Walkthrough aim at being a review of the game that allows the potential player to judge by themselves if it's a game they want to buy, it also aims at being educative to help players finish the game at expert and finally it aim at being entertaining showing a \"good\" performance from Attila. So Enjoy ...
