Those who loved the original Left 4 Dead will find this game even more enjoyable. Almost everything has been improved, including the AI. Other additions to the game include new enemies and melee weapons.

For those that prefer to play with AI, this is one of the best co-op games for offline bot play.
Pro Low Spec
This game can practically run on a potato.
Pro Melee weapons have the best visceral experience
Left 4 Dead 2 includes melee weapons for the player to use during the game. These allow for not only more graphic violence, but also a more personal and visceral experience.
Cons
Con Difficulty can spike from chapter to chapter
Con Boring
Con Tower defense games do not invite creative building plans
Con Boss models are reused too much
There is not a ton of variety in the boss battles; boss models are reused often. This can be repetitive for players.
Con Very difficult without team engagement
For those looking for a casual co-op experience, Left 4 Dead 2 probably isn't the best option. Without a good sense of teamwork and focus, this game can get very challenging.
Con AI not the smartest
The AI has a tendency to make ridiculous choices that can screw up what players are doing. This can become a big problem when relying on AI teammates in order to get through a level.
Con There is no variation of gameplay
Making it very boring after a few hours of playing. Slaying zombies is fun and all, but it gets exceptionally dull once the "wow" effect of blowing zombie's brains out wears off.
Con More of the same
While the game has been improved compared to the original, there are no wildly different game mechanics. If you did not have much fun with Left 4 Dead, you will probably not get much enjoyment out of the sequel. Some have gone so far as to complain that it feels like a large DLC update rather than a discrete game.
