Cons:

-Special Infected can spawn quite quickly that it becomes annoying
-Sometimes it is hard to walk past the survivors
-In one part the horde randomly became alerted
-Hard to tell apart the zombies from the chargers in the nether.

Conclusion:

This is an amazing campaign, it is one of the best me and and my stepbrother have ever played, it is full of challenges, easter eggs, crafting and epicness! I could not believe my eyes when I played it, it was so cool!

Pros:

-Really funny
-Awesome model
-Goodly detailed

Cons:

-Sometimes he glitches with the original hunter model, which can look weird.

Conclusion:

Good mod, just one glitch, I really like it, you should get it, unless of course you are a german.

Pros:

-Fun Campaign
-Some items from The Passing
-Lots of Zombies to fight
-Variety of Uncommon Zombies
-Panic Events
-Full Chapters

Cons:

-Panic Events may happen quite often
-Most of the special infected that spawn are Spitters, Hunters, Chargers or Jockeys.
-Usually when a Spitter spawns there will normally be 2 Spitters
-On the poster it shows the L4D1 survivors and according to the other reviews the L4D1 survivors are in the campaign, however when I played, as they are supposed to be in Chapter 5, they weren't, so that may be a glitch but I don't know, yet in one bit it said "Louis killed Boomer" but he was nowhere to be seen.
-The last panic event can be long and boring.

Conclusion:

This map is great fun and I enjoyed playing it (especially since I was also using a Justin Beiber skin for the witch, which was entertaining. I really recommend this campaign, however it can be at times similar to The Parish & Panic Events are quite often, and there are lots of Zombies, more than usual in Panic Events, so if you don't like fighting TONS and TONS of zombies, then meh, look away from this campaign. My only other problem is the ending with the train, as I said in the Cons. There are no credits for this Campaign, and when it ends Left 4 Dead 2 shuts off and you will return to your desktop.
