Hi Kapow,
The pledges are for the layouts shown in the photographs of the pledges.
We will be adding an 'Add On' deal later in the week that contains 4 x Terra-Former Bunkers & A Terra-Block Starter & Deluxe Starter (which is enough Terra-Blocks to fill the four tiles as shown).
The other option is to go for the £1 pledge that allows you to just get individual tiles.
This photo shows how the caves and cliffs work with the bunkers.
This photo shows a single bunker tile kitted out with Terra-Blocks. 7TV miniatures from Crooked Dice and furniture from Copplestone, Black Cat and Crooked Dice.
I've just posted an update on bunker tile on Kick Starter:
