This co-operative action horror FPS takes you and your friends through the cities, swamps and cemeteries of the Deep South, from Savannah to New Orleans across five expansive campaigns. You'll play as one of four new survivors armed with a wide and devastating array of classic and upgraded weapons. In addition to firearms, you'll also get a chance to take out some aggression on infected with a variety of carnage-creating melee weapons, from chainsaws to axes and even the deadly frying pan.

Left 4 Dead 2 is a game by Valve for Windows and Mac. It is better than Left 4 Dead 1 and the multiplayer is sooooo much fun. So the game-play is also better.
