Featuring the modes that made the first game so successful, Left 4 Dead 2 adds to the fun with “Realism” and “Scavenge”. Realism takes you through 
the campaign, which now features four lengthier levels instead of five, without any of the features that make the game much more manageable. Allies are no longer highlighted through walls, weapons and items no longer respawn, and the only indication you have of an ally being dragged away by a smoker is the distant sound of his screams from the other side of the hallway. Scavenge, similar to Realism, pits you in the last level of each campaign, which now has you searching for objects instead of defending an objective. The two new modes are awfully impressive but, at the end of the day, you’re still going to have trouble peeling yourself away from the versus mode.
The character and items models, particularly those of the zombies, have been increased significantly and make for a much more enjoyable experience for your eyes. Not that the first game had any problems with it, but survivors are very easy to distinguish from zombies and, with the exception of the two pistols, the guns are too. Sadly, the guns still sound weak, but the zombies in L4D2 sound absolutely terrifying, especially 
the witch. Moans and grumbles galore, you’ll constantly find yourself whipping around constantly expecting to see someone or something charging at you.
The lack of a prevalent story really keeps L4D2 reaching the upper echelon of titles of the decade, but, gameplay wise, it’s hard to deny L4D2 has already become the methamphetamine of gamers today. New additions keep the title feeling as fresh as ever and, more importantly, worth every penny Valve is charging for the title.
