Valve's Left 4 Dead is an ambitious undertaking. The idea is to combine the narrative strengths of Half-Life with the infinite replayability of Counter-Strike. Designed from the ground up with multiplayer in mind, Left 4 Dead is the story of four of humanity's last survivors, as they attempt to survive in a world overtaken by the Infected. It's a zombie-action story in the same vein as "28 Days Later," with fast-paced combat and plenty of emphasis on teamwork. Nice Commercial of it http://gamevideos.1up.com/video/id/22377 Here is another trailer, http://www.gametrailers.com/player/42271.html. I heard that this is the only cut scene besides the ending, the rest is just fighting zombies through the whole game.
