    It remains one of the most distinctive co-operative titles out there, and allows for some of the most nerve-searing team-based multiplayer gaming on the market.
  2. With exciting new content across the board and plenty of it, Left 4 Dead 2 outdoes its predecessor and makes the zombie apocalypse an absolute blast.
  3. With more modes, weapons, health items, special infected - you name it! - L4D2 feels like a massive upgrade from the original L4D.
  4. Left 4 Dead 2 is swollen with action that will leave your controller sweaty and worn, and emerges as one of the most powerful online co-op experiences I have ever had.
  5. 90
    When it was first announced, I thought Left 4 Dead 2 was nothing more than a glorified expansion. After having spent hours with it -- and many more to come -- I appreciate the sequel's major and subtle differences.
  6. Whereas once we treated Left 4 Dead as a stopgap between Half-Lifes, this is no longer a weird little side project with modest expectations, and Valve is confident enough to play around with it, safe in the knowledge that you can trust your players. Left 4 Dead proved it. And whereas that game had a personality, this one is overflowing with it.
  7. Anyone telling you that this game isn't different or changed from the first game is flat out lying to you. L4D2 isn't going to change your mind if you thought it was just okay or didn't care for it. On the other hand if you and a handful of friends enjoyed joining up to defeat the land of the dead and surviving the thought of being a smorgasbord for the flesh eaters, then you will have nothing short of a blast with L4D2.
  8. Left 4 Dead 2 may have lost some of that new zombie smell, but its cooperative play is still among the best.
  9. 100
    L4D2 delivers multiple improvements over its predecessor, and I get to keep all my fingers and toes.
  10. More maps, more enemies, more weapons, more glorious spectacle than the original, and that’s just the co-op. Fresh versus modes and intense violence make this the apocalypse to beat.
  11. L4D2 may be more of the same, but in a thoroughly pleasing sense.
  12. Left 4 Dead 2 takes the best from the first game and improves it. Despite the few technical advances, Valve has make the most of its time these months and has improved, when possible, every aspect of the original game.
  13. 100
    Left 4 Dead 2 is the Empire Strikes Back of zombie games. The momentum has clearly swung in favor of the bad guys. But also much like Empire, this is clearly the best of the bunch and is a required purchase for fans of the genre.
  14. If L4D2 is sometimes over-complicated by its glut of small innovations, then it also substantially rewards the player with its few large ideas: confusion gives way to depth and dynamism, grander thrills and starker dramas. We’re still interested in the fate of the original game’s heroes, but this sequel affirms that the way ahead is due south.
  15. A top-quality shooter with oodles of style.
  16. Left 4 Dead 2 is again one of the most intense, visceral and violent co-op shooters of this holiday season, but to be honest we were expecting some more additions. The game improves in every area its former game, but this is not enough to justify just 12 months of gap between the first and second iterations.
  17. When the storms kick up on Hard Rain making it really easy to startle a wandering Witch, escaping the mall in Dead Center, running around a rollercoaster track in Dark Carnival, running a gauntlet of abandoned vehicles across the bridge in The Parish, reviving a dead Survivor in Swamp Fever as a Tank could be heard somewhere behind me and managing to down the Tank with the guy I just saved. Even just writing about it makes me want to jump in and play some more.
  18. For Left 4 Dead fans, there's more zombie killing fun in this one and it does feel different from the first game. The many additions really help expand the game and almost makes the first game seem like a beta.
  19. Five new campaigns, two multiplayer modes and many new features are big deal for everyone who loved the first Left 4 Dead. It's still the best cooperative experience you can find out there, so be a good boy and get yourself into some good ol' zombie creaming. On the other hand, whoever didn't get involved with the first one won't have any reason to get this sequel.
  20. It is a much more refined game than Left 4 Dead and an improvement in every way.
  21. Left 4 Dead 2 is a great sequel. Bigger and more variation in the gameplay – it is how it should be.
  22. Don't like forced humor and bright colors, but do like everything else. Especially Spitter. [Dec 2009]
  23. It is just more of the same, but however minor the improvement this is still co-op gaming at its best.
  24. 85
    The PC version mirrors all of the good stuff and can be confidently defined as a title that is going to be hours of fun to PC gamers the world over.
  25. If the player were disappointed by this scenario in the original, he'll probably be disappointed now too. However, with a wealth of new content and lots of other welcome additions and tweaks, Left 4 Dead 2 continues to focus on what it does best, and it's damn good at it.
  26. L4D2 is a splendid cooperative mayhem with an excellent performance ratio. We only expected it to be more innovative compared to the previous chapter. [Issue#186]
  27. Although the game's a brain splattering good time, we still don't understand why Valve refuses to allow users to aim down the sights of a weapon, instead of always shooting from the hip. It gets the job done most of the time, but we feel everyone's accuracy would improve if they could line up their shots.
  28. Those of you who had doubts about this being just another glorified expansion need to stop yelling at Valve and give Left 4 Dead 2 a try, as it is incomparably better than the first game by a large margin.
  29. Despite the new changes and how much they add to and improve the overall gameplay, it still feels like the same fun zombie killing game at its core.
  30. Gorier, chainsawier, co-opier, and more infectious. A refreshed stack of content for the best zombie game ever.

    People, you can't downgrade a game meant to be coop because the Single Player is lousy. It's also not clear if you should be rating L4D2 relative to L4D, since that rating wouldn't matter to someone who doesn't have either. Rate L4D2 on its own merits, for how it's meant to be played, and if you do that, the game is practically flawless. Full Review »
