Get discounts for Left 4 Dead Steam Key at G2A. From Valve (the originators of Counter Strike, Half Life and more) comes Left 4 Dead, a coop action horror game for the Computer that casts up to four players in a heroic battle for survival against swarming zombie hordes and terrifying mutant creatures. Place in the immediate wake of the zombie apocalypse, L4D's survival coop mode allows you to smash a path through the infected in four distinctive “pictures,” directing your survivors across the roof tops of a deserted metropolis, through rural ghost towns and pitch black woods in your quest to escape a ravaged Ground Zero crawling with infected enemies. Each "picture" is made up of of five big maps, and may be performed by one to four human players, with the emphasis on team-based strategy and goals. New technology dubbed "the AI Manager" can be used to create a distinctive gameplay experience each single time you play. The Manager tailors the frequency and ferocity of the zombie attacks to your own performance, placing you in the midst of a fast paced, although not overwhelming, Hollywood horror movie. FeaturesAddictive single-player, cooperative, and multiplayer action gameplay from the manufacturers of Counter Strike and Half-LifeVersus Mode allows you to compete four-on-four with buddies, playing as a person attempting to get saved, or as a zombie boss creature that'll stop at nothing to ruin them.
