Pros:

-'Scares' are really cool and unique
-Castle looks really nice in the day

Cons:

-2nd map is wayyyy to dark, can't see anything outside of my flashlight most of the time leading to a lot of incaps that should be avoided
-No real direction where to go in the 2nd and 3rd map. Spent a lot of time wandering around trying to figure out what to do.
-Really tough to tell where the finale helicopter lands
-Finale had so many zombies spawning that the server started lagging. No need to have that many going at once.

Conclusion:

Some cool ideas, just needs some refinement. Would love to see more scares like in the 2nd map, but have a bit more ambient lighting overall.

Pros:

-Pretty fun
-A really cool take on a coop type of scavenge
-Everything works really smoothly
-Can be nicely challenging on Expert

Cons:

-Needs a VS mode

Conclusion:

Add a VS/Scavenge mode to this and I can see it getting a lot of plays.

Pros:

Looks fantastic. Very creative design. Best water I've seen in any L4D campaign.
Level design is very well done.

Cons:

Co-op mode is pretty short, and it's not clear what to do with the object you find at the end.

Conclusion:

Love the look, would love to see some more maps in this style. Only complaint is that we didn't know what to do in the coop until we started wandering around randomly.

Pros:

Fantastic remake of the original ride
Some fun secrets to find
Fun to go through even without the zombies

Cons:

Adding more easter eggs/secrets would add some replayability, but its still great

Conclusion:

Really fun map to go through. The first time we found a secret we excitedly looked for all the other easter eggs and it added a good 20 minutes to the map length. Not sure if I'd play it more than once, but I highly recommend anyone to play through it.

Pros:

-Overall good design
-No bugs or glitches that I saw in coop or VS
-Great lighting in the finale, looks really nice

Cons:

-Going through the building can get a bit boring - all the hallways and staircases look the same. Not a huge issue though.
-Might be way unbalanced, but I'd like to see how it would play if the Chargers could charge through all the glass to the outside

Conclusion:

A pretty solid campaign. Works pretty good in both Co-op and VS. Havent tried the Scavenge or Survival modes yet though, I'm not a big fan of those. The wind on the finale platform is a neat idea, but there's no indication of it until you get blown off.

Pros:

Great pacing
Great lighting
Music fits in perfectly

Cons:

Nothing really, perhaps the finale is a bit plain.

Conclusion:

One of the better full campaigns available for L4D2 right now. Havent tried it in VS yet, but it looks like it'll be great for that.

Pros:

-Nice details
-Solid design
-Good variety

Cons:

-2 people in my group complained of major fps issues in the 2nd map. They had to disable multi-core rendering to fix it
-Also missing some textures in the 2nd map
-In the elevator on the first map, if you jump while its going down you get stuck on top of it and cannot continue.

Conclusion:

A great start, just a couple bugs so far. Excited to see what else is coming up in the rest of this campaign.
