You cant keep a good game down even if its filled with the living dead. In celebration of multiple Game of the Year awards and status as the best selling new franchise of 2008 Left 4 Dead Game of the Year Edition combines the original zombie apocalypse outbreak with the new Survival Pack offering all the great bone-chilling challenge of normal L4D plus a new Survival Mode.Rather than Left 4 Deads objective-based single-player and four player co-op modes Survival is a struggle against the inevitable as a never-ending barrage of zombie hordes spills into 10 different maps. Joining it are two new Versus campaigns each with five maps allowing four-on-four battles where a team of heavily-armed humans and specially powered Boss Infected square off.
