  1. This is Valve trying to better L4D1 in every way, succeeding but never really breaking away from what did work first time, taking creative risks and really pushing the series forward. In any case play it, love it, it’s one of the best multiplayer games I’ve ever played.
  2. Left 4 Dead 2 is a perfect example of what happens when a competent developer takes an existing game and adds just enough to make it better, without subtracting from its initial appeal.
  3. Left 4 Dead 2 manages to recapture the strong points of the first game while improving on them too. If the real zombie apocalypse is going to be as fun as this one, you have nothing to worry about.
  4. 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.
  5. Left 4 Dead 2 is simply a must-have for all survival horror enthusiasts. The new game modes and the usual mix of adrenaline and co-op gameplay is the living(dead) proof that a sequel doesn’t always have to change its original nature to be enjoyable, very enjoyable!
  6. Valve has done it once again. Left 4 Dead 2 takes everything that was amazing about the first installment and puts it on steroids.

    Left 4 Dead 2 is – despite the same formula – a big step forward. People who have played the first game, will feel a little cheated, as there aren’t many changes. Following the umpteenth adrenaline rush with your friends however, you will have forgotten all about that. The many extra’s in this second installment justify it being a stand-alone version. Hours of gameplay await that you cannot find in every co-op shooter. Simple but deep, it’s not a given in every game.

    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.
  9. 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.
  10. Left 4 Dead 2, like the first one, is a fun and replayable co-op experience that can be tons of fun with a group of friends. Unfortunately somewhere during the drive to add more and more weapons, enemies, maps and game modes, that magic Valve iterate-polish-polish cycle got cut short and the end result, while still good, is not quite as magical as the first one.
  11. Left 4 Dead 2 is a great sequel. Bigger and more variation in the gameplay – it is how it should be.
  12. On the one hand, this could have been a less expensive DLC for Left 4 Dead, just like it was done for Team Fortress 2. On the other hand, we don’t really care, once we’ve chocked someone to death as a Smoker or hit someone with our fist as a Charger. That’s only possible in Left 4 Dead 2.
  13. The new weapons, Infected and graphical update is the shot in the arm players were looking for to expand the PvP experience.
  14. 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.
  15. 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.
  16. Looking back at Left 4 Dead 2’s offerings, it’s hard to call it “just a $50 expansion pack.” All worries and boycotts were in vain; you can’t go back to the original Left 4 Dead after playing this one.
  17. What makes L4D2 a great game is what made the original so popular: exhilarating co-operative action with three buddies… and zombies.
  18. It may have been a close call, but to us L4D2 really did manage to become more, then just a "full-price-addon". It's a definite must-have for fans and the best co-op experience money can buy.
  19. 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.
  20. 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.
  21. It is a much more refined game than Left 4 Dead and an improvement in every way.
  22. 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]
  23. Dripping with style and generously packed with content, Left 4 Dead 2 refines every aspect of its predecessor. [Jan 2010, p.82]
  24. There is simply far more content by volume in this package than in the original. The core of Left 4 Dead may have lost some of its newness in the last 12 months, but the wealth of additions in this sequel ought to keep you blasting zombies and munching on brains for a good long while.
  25. Left 4 Dead 2 may have lost some of that new zombie smell, but its cooperative play is still among the best.

    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 »
