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.
The fact that they made L4D2 a bit later after the first L4D isn't a good sign. Seems like the creators were purposing leaving things out in the first version to make some money in the second. I did not really like the characters in L4D2. In addition, the super infected in L4D2 seemed very childish compared to the ones in L4D.
