Pros:

original design, models and idea.
really immersive design, (puts you into the game)
great changes to the sewer area
fantastic flow of play, (easy to follow through without getting lost)
Ambience was exquisite
original finale creation(explanation of issue in conclusion)
great use of varying paths(some games it changes at the horde pile(factory!?!) fence that makes you alter your path!
sewer plant 2 (where the gate opens and alarm sounds), improved: old version had a ladder to climb now it is a set of stairs.. perfect!

love the finale where you have to insert tanks to get the train to lower(spoiler**) but yet an original idea none the less!

Cons:

the altered path at the body pile and tower, second map, had some troubles getting stuck crouching out tower windows(though well marked) to climb down wood plank pathway. (minor annoyance)

other than that.. no real cons!

Conclusion:

This campaign is superb in its originality. this is a favorite of my wife and I for some time, even since the beta days.

known issue**  Use of super hordes v3 messes up the finale to the point that the guy who is supposed to throw tanks down to you to lower the train doesn't appear. he will acknowledge that the system has crashed and the hydraulics are broken or not working. CAREFUL WHICH MODS YOU USE, THIS COULD AFFECT FINALE SCRIPT TO MALFUNCTION!!! This isn't any issue on the part of the developer, just conflicts with the finale script...

openings in the floor open and under the train to place these hydraulic tanks into place to get the train to lower. The entire campaign is well thought out and original. I understand it took the developer some 2 years to complete, improve and alter and time well spent! this campaign is tied for 1st place in my favorite campaigns along side of bloody moors. This is a must have on any server!

Pros:

Excellent original campaign (original music score)
original campaign maps
tank models converted to wherewolves (major plus)
original voice overs for interesting originality (UK)
terrain is exquisite, dark and always interesting
good use of original models used in the entire maps (except the cemetery) stock tombstones used)
great transition to the catacombs and tunnels
the beach area (finale) excellent useage of textures as well as the dock
phone booths, to include the one where you answer to hear a guy trapped insind a building was original touch

alot of similarity however with the original campaign "dead center" usageof the guy to make a deal, the meat for the key to his boat to escape.. but original voice over in true UK language...hilarious touch!

Cons:

maybe a tad too many spitters (a minor annoyance)
maybe.. maybe a few more health kits in varying locations.(due to some locations of 2 werewolves(tanks) and you get really pounded.
at the river, no real clue as to how to get at the M60 and supplies behind the gate(or is this a hidden task to figure out?)
not maybe a real CON however, maybe some better marking of directions to go in within the underground caves??)

Conclusion:

one of the maps you have to follow and head toward the flares as they are markers to show where you must go. The entire campaign are 90%  original models of UK area. it will make you believe you are actually in the UK. Spot on details of each map and weather as well. Great use of the custom models for the wherewolves. be prepared for a couple locations of dual wherewolves. superb immersion and great usage of outdoor and indoor gameplay in one campaign. be patient traversing the catacombs, they are huge! The cons, are in NO WAY, any detractor to the overall score, as this campaign has more originality in terms of design, custom models and terrain than ANY map I have seen. this is by far one of my favorites alone with Morlocs redemptionII. My hats off to great work and attention to details!

Pros:

excellent render of Disneyland!
exceptional fun in a REAL known park

Cons:

in future work if any, would love to cross park into tomorrowland and go through buzz lightyear and some of the rides over there.. unless that's way too much to ask.
(not a con)

issue with error messages in game fixed with the "left for dead 2 missing content mod" at: http://www.gamemaps.com/details/8719

Conclusion:

overall perfect and the attention to detail makes my wife miss going to disneyland when we play this... 5 stars
