Fast zombies? Check. Non-stop tension and intensity? Check. The quality of gameplay we expect from Valve? Check. When it comes to co-op multiplayer, Valve is consistently ahead of the curve and excellent at making games that force players to work together.

Left 4 Dead's simplicity offers purity of gameplay - the same reason that gamers keep returning to classic arcade games. Come to think of it, with a handful of levels and unpredictable events happening within them, Left 4 Dead has more in common with "Ms. Pac-Man" than just the eating. It's the same thing over and over - but when simple ingredients are perfectly prepared, what could be a mere snack becomes a feast. This one just happens to be on human flesh. [Holiday 2008, p.32]

If you are even thinking about playing this game, pony up for the Xbox Live Gold membership. It’s just as necessary as the controller. While light on content, Left 4 Dead needs to be in everyone’s library, not only because it innovates in ways that will shape the future of gaming, but also because it’s so damn fun.

One of the finest zombie games ever made, and one of the finest co-op games ever made. The potential for everything to go so, so wrong without warning, or conversely to pull off the most spectacular escapes against all odds, means this is an online shooter you can tell your finest anecdotes about without boring everyone else to tears.

Simply put, every time the Director brings down a swath of Infected, who then pound me into hamburger, and every time my team and I manage to survive against incredible odds until the end, and we hoot and holler about besting the Director, I do the same thing: I jump into another lobby and wait for a match to start. I love this damn game.

It’s so immersive and satisfying to sling lead at an infinite number of creepy, crawly zombies! It’s not particularly deep, but there are far more moments that’ll make you grin goofily and move tensely to the edge of your seat.

Valve has taken something unscripted and dynamic, and seeded it with the right amount of narrative flavour, pacing and spectacle. [Christmas 2008, p.82]

There's absolutely no doubt that Left 4 Dead is one of the most social and exciting multiplayer games that we've ever played. It's almost pitch perfect in how it captures the tension and the action of a Hollywood zombie movie.

The inventive and highly entertaining competitive multiplayer mode just adds to the experience, and we're looking forward to seeing what Valve's got planned for the game's future. Out of all the titles that have shaped the Year of Living Cooperatively, this may be the best experience of them all.

The only thing missing from the game is a decent story for the single-player mode. I understand that this is a game made for online play, but you get this really great animated opening that kind of lays down a general plot and that’s it.

Left 4 Dead is largely successful at bringing players a uniquely exhilarating, arcade-like zombie shooter. The eye toward multiplayer fun is definitely appreciated, and the accessibility is great. However, the experience is best taken in short bursts, as the repetitive action gets monotonous after awhile.

Giant Bomb
Beyond its categorical success in establishing a vivid picture of the zombie apocalypse, Left 4 Dead's biggest breakthrough is the way it blurs the lines between the often compartmentalized pieces of a modern first-person shooter. It makes for a game that's unlike any other, and while the limited amount of content is admittedly unfortunate, that shouldn't keep you from experiencing this fast-paced, nerve-wracking game.

Although we zipped through the four "movies" in less than five hours, we can't stop playing co-operatively with friends via online play and competing against others in the thrilling Survivors vs. Infected, a four-on-four multiplayer mode where monsters attempt to slaughter their gun-wielding adversaries.
