Pros:

Eerie atmosphere (Map 2)
Nice lighting
Ability to light campfire
Random jump scares 
Those random team messages

Cons:

Too many hordes
Too short
Finale too easy
Could make "ladders" more easy too fine
A little too dark (Doesn't matter though I use a mod to make my flashlight brighter)

Conclusion:

This campaign was interesting, but when the constant hordes start showing up it seriously ruins the whole creepy 
atmosphere. Regardless though, I enjoyed playing through this campaign.
