Left 4 Dead 2 is the sequel to the best-selling and critically-acclaimed co-op multiplayer smash from Valve, creators of the Half-life, Portal, Team Fortress and Counter-Strike game properties. With multiple multiplayer options both on and offline, extensive AI custom functionality, four character options, new melee weapons and more, Left 4 Dead 2 becomes one of the best shooters on the PC platform and sets a new benchmark for co-op centric action games.

Just as with the original Left 4 Dead, Left 4 Dead 2 is a first-person shooter which pits players against hordes of zombie-like enemies. As you would expect in a scenario where you are regularly surrounded by masses of the undead, it is very good thing to have plenty of help, as well as weapons at your disposal, and Left 4 Dead 2 has players covered on both accounts. The game features several multiplayer options including 2-8 player online and offline support in several modes seen in the first game, including Campaign, Versus, and Survival, as well as the new Scavenge Mode. This new multiplayer option tasks players, in the role of survivors to find a limited number of fuel canisters hidden in a level in order to keep their individual generators going, while other players in the role of the infected try to stop them. In addition the game features very strong co-op play support, with 2-player support locally and 2-4 player support online.
