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.

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.

I don't know what to say, this game brought me here. A gr8 example of using the game's full potential. Give a chance to the classic, now that it's cheap, see how it all started or just pay your respect to Valve. I loved it, I still do and I always will. No number can rate this, it's a heart-case for me.

Left 4 Dead is evil. It's gaming experience is dark, viserally frightening and frequently so intense that it will have you looking over your shoulder just to confirm there isn't a zombie behind you.

That is why it is so incredibly awesome!

So, without any further delay here are my top 10 reasons for why you should definitely buy Left 4 Dead:

1. The survivor characters are well thought out and very relatable.
2. The game has excellent replayability, even in campaign mode.
3. The achievements are carefully crafted, challenging and completely addictive.
4. It does what a zombie game should do: scare the crap out of you.
5. Multi-player is encouraged, rewarding but not always necessary.
6. The varying difficulty levels actually make a difference (just look at my hours on expert)
7. You can play as special infected in multiplayer mode!
8. The level and campaign design is amazing.
9. It's one of the best zombie FPS games ever.
10. It's just so much bloody fun!

My only criticism is that sometimes the available weaponry options feel restricted and limited, but that just adds to the challenge.

You don't just play Left 4 Dead, you experience Left 4 Dead.

So experience it today!
