This was a KS-exclusive add-on, that basically gave you a set of the different plastic terrain choices they were offering during the campaign.  It came in a quite large box:
And has everything nicely packaged.

Per the campaign, the contents are:
  • 1 Trees Set
  • 3 Hedges
  • 3 Palisades
  • 3 Stakes
  • 2 Ruined Walls
  • 1 Low Wall
  • 1 Bog
  • 1 Weirdwood Tree Set
  • 4 Corpse Piles
  • 2 Plateau
So for simplicity, I'll just follow this order to show the pictures.

Tree Set:
 
Hedges:
Palisades:
Stakes:
Ruined Walls and Low Wall:
Bog (this is flat on the board):
Weirdwood:
 
Corpse Piles:
And the Plateaus:
If I listed more than one of something up top, but didn't take a picture that OBVIOUSLY had more than one of the item in it, the duplicates are identical (for example, I have two identical plateaus).

The terrain is really nice, and the colored plastic will make them look quite nice on the table until they can be painted a little (really, just a little drybrushing would probably make these look amazing).  As a miniature wargamer, you can never have enough terrain- although this is a great set of stuff to help ensure I have some interesting tables to fight over.  Great quality, good size, and quite a good amount.
