Little did you know that the diminuitive, statuesque grandpa you were tasked with lugging around in Half-Life 2: Episode Two and Left 4 Dead 2 was actually a stationary action hero. Check out FineLeatherJackets' trailer for Gnome Chompski's (totally not real) video game posted after the break.
Left 4 Dead 2 is set at roughly the same time as the original just after the outbreak that turned most of the population into various zombie mutants. Players assume the role of 4 new "Survivors," each with their own personality and new dialog. The game leads these "Survivors" through the southeastern region of the US - from Savannah, Georgia through the bayou country, and climaxing in New Orleans' French Quarter.
