Left 4 Dead 2 + Multiplayer

Real zombie apocalypse, Left 4 Dead 2 (L4D2) — is the highly acclaimed sequel to the award-winning Left 4 Dead — the best co-op game of 2008.
In this first-person co-op horror shooter, you and your friends will navigate five large campaigns through the cities, swamps and cemeteries of the very south of the United States, from Savannah to New Orleans.
You will play as one of four new survivors, using a variety of furious guns to fight the enemies, including updated instances from the first part of the game. In addition, you can unleash your aggression on the infected with terrifying melee weapons such as the chainsaw, axe, and deadly frying pan.
All of these toys you will have to use against three terrifyingly scary new Special Infected (or they will already be used against you). In addition, you will be able to meet five "non-standard" regular zombies, including the frightening Mudman.
The addictive gameplay of the first part of the game is taken to a new level by the updated "Director". Now he can change the weather, paths, not to mention the number of enemies, effects, sounds and other things that will suit your level of play. Each time L4D2 will "experience" in a new way you, changing the approach to you and adapting to the style of your game.
