Pros:

-Better than the original Crash Course
-Jets
-Objects falling off buildings, creates a nice dynamic feeling
-Old Survivors
-The generator stops more during the finale

Cons:

-Too many hordes
-Too many tanks
-Too many witches
-The flood on Chapter 2 makes no sense, why would a 5 min. shower cause a hurricane-esque flood?
-The intro dialogue is missing, but I used custom radial menus to fix that
-The bots like to get shot by the military personel

Conclusion:

It's okay.  Some things could have been tweaked here and there, but it was a pretty fun campaign all around.

Pros:

-Still original white suit
-Hawaiian shirt
-Fits his "gambling con-man personality more
-Sweat/bood/vomit stains on suit
-Black eye
-Claw marks on neck
-Gold chain

Cons:

-None

Conclusion:

This probably should have been the default skin for Nick.

Pros:

-Look better than the actual posters
-Nice level of detail
-The Passing looks especially nice
-Custom loading bar

Cons:

-Cold Stream doesn't work

Conclusion:

They look okay, but if there's some fix for Cold Stream's poster in the future, that would be nice.

Pros:

-With Coach being the voice of reason and authority of the group of survivors, being a police officer makes Coach look more serious than being an ex-high school football coach
-I'm a fan of police, so it scores extra points for me
-Good high quality skin with no bugs or issues

Cons:

-None

Conclusion:

Definitely worth a download.

Pros:

-L4D survivors!
-Continues after Crash Course, which is neat
-Francis rants about stuff
-Nice conversations between survivors
-Domo-kun easter eggs!
-Multiple pathways every time you play
-Custom graffiti (GRABBIN PEELZ' was on one of the walls)
-Unique locations
-Complex scripted events
-Epic finale
-Nice rescue vehicle
-There's TWO rescue vehicles in the campaign, one crashes

Cons:

-Can be confusing the first time through

Conclusion:

A well made map with not too many things wrong with it.  I'd definitely download it if I were you.

Pros:

-Nice storyline that is somewhat canon
-L4D2 survivors
-Not many bugs or issues come to mind
-Jimmy Gibbs Jr. car returns!
-Good selection of weapons and their locations

Cons:

-Kind of short
-So.  Many.  Tanks.
-Hordes and crescendos can last too long, and be more aggravating rather than challenging
-A lot of the map feels like it was taken from other maps (get the gas, start the generators, turn off the alarm, etc.)
-Map isn't exactly straightforward, you might get lost a couple of times

Conclusion:

A nice campaign.  Not too long, but not too short, either.  Not the best map, but still pretty good.

Pros:

-Decent length
-Not too difficult
-Unique and interesting horde/crescendo events
-Straightforward, no backtracking or confusion
-Foam Finger melee weapon!
-Football player Tanks!
-Voice acting from the creators of the map
-Amazing custom music
-Nothing feels half-assed or recycled
-No AI or pathfinding issues

Cons:

-If you die on singleplayer with sv_all_bot_game set to 1, the bots will move around, but won't press buttons and such
-Finale is a tad overwhelming the first time around

Conclusion:

An engaging and wonderful campaign that is sure to bring many hours of replayability.  The creators obviously put a lot of time and effort into this map, and they deserve all the positive reviews they get.
