Left 4 Dead

Left 4 Dead 2 is the sequel to Left 4 Dead. Players are one of four new survivors armed with a wide and devastating array of classic and upgraded weapons. In addition to firearms, a variety of carnage-creating melee weapons have been added, from chainsaws to axes and even the exceptionally deadly frying pan. Left 4 Dead 2 also introduces new campaigns and more game modes.

Left 4 Dead 2 runs on the updated version of Left 4 Dead engine branch, with features such as water flow maps and the VScript virtual machine for scripting.
