Left 4 Dead 2 takes place at roughly the same time as the original, and leads four new "Survivors" through the southeastern region of the U.S., from Savannah, Georgia to New Orleans' French Quarter. The game adds melee combat, new monsters and weapons, the AI Director 2.0 advanced technology, and more to create a much larger game than the original.
Left 4 Dead 2 is targeted for release on Xbox 360® this November.
