It's considered to be the worst l4d2 campaign but for me the vibe that I got from the environment and the forest map overall was great, can't really critique this one.

Really fun campaign with a unique location and atmosphere. Personal highlight being the part in the second act where you have to dash to the safe room. Although still shorter than most main campaigns, it's pretty long for a DLC one.
My only real complaint is that the finale is a bit dull and just feels like a regular level.
