This terrain is a pretty cool idea but it needs some improvements like connected rail systems, more fleshing out of the bunker so it has all of it's walls, and possibly zepplins that you can interact with (crash into, destroy, walk on, etc.). What I want to know is when or if an update will be worked on. It's ok if you don't want to update it but the suspense is killing me. Who knows, maybe if you announce that you will no longer be working on the terrain someone else might take up the helm and work on this terrain.
