Left 4 Dead 2

Left 4 Dead 2 is a first-person shooter for the Xbox 360 and PC, released in 2009 by Valve. Set during a zombie apocalypse, L4D2 follows the exploits of four "Survivors" as they fight their way through the Deep South; one of these Survivors, Ellis, has the distinction of being the only Left 4 Dead character to appear in a Character Battle. L4D2 places more focus on the storyline than its predecessor, which lacked significant plot development - in addition, it also proved to be more violent, which has made the game controversial in some territories. Nonetheless, though, the game received a good deal of acclaim upon release.

In 2010, Left 4 Dead 2 made its contest debut during the "Game of the Decade" tournament. After a poor performance in the first vote-in poll, it received a 15-seed and was fed to fellow Valve title Half-Life 2 in the first round.
