About the Game

From Valve (the creators of Counter-Strike, Half-Life and more) comes Left 4 Dead, a co-op action horror game for the PC and Xbox 360 that casts up to four players in an epic struggle for survival against swarming zombie hordes and terrifying mutant monsters.
Set in the immediate aftermath of the zombie apocalypse, L4D's survival co-op mode lets you blast a path through the infected in four unique “movies,” guiding your survivors across the rooftops of an abandoned metropolis, through rural ghost towns and pitch-black forests in your quest to escape a devastated Ground Zero crawling with infected enemies. Each "movie" is comprised of five large maps, and can be played by one to four human players, with an emphasis on team-based strategy and objectives.
New technology dubbed "the AI Director" is used to generate a unique gameplay experience every time you play. The Director tailors the frequency and ferocity of the zombie attacks to your performance, putting you in the middle of a fast-paced, but not overwhelming, Hollywood horror movie.
  • Addictive single player, co-op, and multiplayer action gameplay from the makers of Counter-Strike and Half-Life
  • Versus Mode lets you compete four-on-four with friends, playing as a human trying to get rescued, or as a zombie boss monster that will stop at nothing to destroy them.
  • See how long you and your friends can hold out against the infected horde in the new Survival Mode
  • An advanced AI director dynamically creates intense and unique experiences every time the game is played
  • 20 maps, 10 weapons and unlimited possibilities in four sprawling "movies"
  • Matchmaking, stats, rankings, and awards system drive collaborative play
  • Designer's Commentary allows gamers to go "behind the scenes" of the game
  • Powered by Source and Steam


"The Sacrifice” is the new add-on for Left 4 Dead.

"The Sacrifice" is the prequel to "The Passing," and takes place from the L4D Survivors' perspective as they make their way South. In addition to advancing the story, "The Sacrifice" introduces a new style finale featuring "Sacrificial Gameplay" where players get to decide who will give their life so the others may live.

In The Sacrifice for Left 4 Dead owners receive "The Sacrifice" campaign playable in Campaign, Versus, and Survival modes.

The true asset and undeniable virtue of this game is the way how the player can find himself still entertained, even after completing every campaign enough times to be familiar with each corner, street, tree and lamp post, after getting to know each weapon, their strenghts and weaknesses and even after the hours you've spent playing this game can be count in thousands.

Yet this game has suffered its turmoil, most of its players have vanished, moved on, and no matter how much you would wish for it, there won't be a reincarnation. Like the rest of them, this game will die eventually. The long lasting appeal may have already been extinguished, but there will be the ones who will continue to enjoy playing it throughout the time, carrying the fire.

I am happy to recommend this game, though I have to admit it's best to purchase the sequel instead. Why? Because currently it is priced around the same level and the sequel has all the campaigns from the previous game included! This means more than a dozen levels with continuous zombie shooting!

In any case, this, just like its sequel, is an excellent game. Although it was released more than 5 years ago I believe it aged well - the game still looks good thanks to the well-developed Source Engine. Years later Valve released many updated including DLCs that expand upon the campaigns - the latest, The Sacrifice, came out in 2010.

Left 4 Dead is a great game! It is a coop-based, action-oriented survival horror game. It is pure fun to get rid of the continuous hordes of zombies with friends game after game! A highly recommended game and not just for the fans of the genre!

This is my first game on Steam, which I've been playing the longest. Before I joined the steam community, I've been playing it for about half a year and then I decided to join multiplayer. I found many friends there and some of them are still around. Sadly, the game was killed by it's own developers. Porting all the campaigns and original Survivors into Left 4 Dead 2 was the last drop in the cup already full. 10/10. RIP.
