Four new heroes, same old zombies. Left 4 Dead 2 was the game I've looking forward to all year. After playing for several days I can say it has its strong and weak points.
For one thing there are more campaigns, but the problem is that some of them are short. New weapons including melee are fun to use. Especially the chainsaw. Controls, graphics, and sound are all great too.
But honestly, this one is much more frustrating than the first one. I can play through the campaigns in the first Left 4 Dead without dying. In Left 4 Dead 2 you can easily die at least four or five times. While this doesn't sound like a big deal, it's just that when you die you have to start again at the last checkpoint, and you have to cover all that ground all over again.
But still, this is a great game. If you liked the first Left 4 Dead then you'll definitely like the sequel.
