-Excellent online multiplayer, matches range from ridiculously easy to frantic and challenging.
-Map design is brilliant and it's great to have a slightly different experience with each playthrough.
-New Orleans backdrop is very stylish and unique, each locale does a superb job of ramping up the action as the campaign progresses.
-Characters and their one-liners liners are distinct and entertaining, such as Coach's "haul *** and get gas!" and Nick's "t**ts!"
-Addition of new types of infected as well as melee weapons is well integrated and bolsters the gameplay variety.
-Some new game modes.

-Not a whole lot of innovation over the original LFD.
-Limited interactivity with the environment. 99% of the time you can't shoot out lights or knock things over.
-Granted, each campaign does have multiple maps, but playing the 5 campaigns over and over again still makes me feel like Valve/EA could be giving us more, but they choose not to for financial and time efficiency reasons.
-Not much backstory, aside from "who are you?" and "let's help each other out of here."
-Would've liked the incorporation of some actual rides (not just shooter games) during the Dark Carnival campaign (run across a rollercoaster track?? ZzzzZzzz)
-There's more they could be doing to expand the horror movie concept behind each campaign some kind of a director mode that lets you edit replays and share them would be pretty slick and not too difficult to implement.
