From the update:
Hello, a long awaited addition to our painted terrain line. We're adding three new industrial buildings at the end of the month. Here's some quick pics of the three industrial terrain pieces.
The final addition is our ruined warehouse building. The warehouse has plenty of room and also comes with a set of doors which can be removed for game play.
All of these terrain pieces are laser cut assembled and painted kits from Mechanical Warhorse and will be available on April 30, 2012.
