Pros:

+Very unique
+Orginal
+Actually scary at times, especially the noise effects and the mansion, very well done
+Nice looking
+Never found any real glitches 

Cons:

-Finale IMHO could of been better, perhaps more routes to take, and a better indication when you are about to reach the end (Minor complaint)
-Overlook on 2nd map, on the street with the 3 houses, the house on the right had a door and I shot it down, to find it was just scenery, not part of the level, ruined the atmosphere a little (minor complaint)
-Missing texture of the fireplace in the 2nd level (minor complaint)

Conclusion:

Overall, I really enjoyed this map. It was fun, orginal, actually scary, and fits L4D very well. Thank you :)

Pros:

+Looks good
+Street battles were fun
+Multiple routes are good
+Custom dialogue a good bonus!
+Good finale

Cons:

-Areas to big, too easy to take out tanks
-Should of probably been split into 5 or even 6 chapters, especially the third chapter, I mean three creschendos is tough, we nearly got wiped out by the end!
-Like someone else said, 2 tanks at the finale was a bit of an overkill

Conclusion:

A good campaign, some work to be had but I think you can do much better campaigns in future =)

Pros:

+Great design
+Looks good
+Every weapon there
+Top on the rig is awesome
+Forces players to camp at top without supplies, meaning frantic gameplay on the last clip of ammo!

Cons:

-Looks like the rig is floating, lol 

Conclusion:

I really like this map, its got great design, and having a tank chase you up the top is very hectic! I would of probably given you 95 but ive gone and given you a 100, just to balance out that idiots score of 1! 

I also cant wait to try tidal surge once its fixed BTW, thats looks like quality too!  =)

Pros:

+Very interesting level design and creativity
+The love child of hard rain and dead centre, which can only be a good thing
+Very entertaining and quite complex for a custom campaign (and in less than 3 weeks! =O )

Cons:

-Can be confusing at times
-Finale was easy and boring
-Can get lost at times

Conclusion:

A great campaign, I do hope you make more =)

Pros:

Almost perfect recreation of HL2 ep1
Well designed
No major glitches
Very fun!
Chapter 4, the ****ing plane!!!!! =D

Cons:

Finale was a little boring and the half life music kept getting muddled with the L4D2 (minor issues though)
Strange amount of witches spawn, but are all pretty easy to avoid usually (minor issue)
Weather effects seem muddled (its a storm, then its dark, then its light???) (yet again, very minor)

Conclusion:

Possibly one of the best custom L4D2 campaigns, I would happily suggest that the author of this should make more, perhaps even make some using his own designs =)
