From their website:
Hi all, just a quick note to let you know that the 15mm modular sci fi field fortification that we previewed back in November, KILO OUTPOST, is now available.
The starter set is the minumum possible size as we didn't want to play the guessing game of how big each gamer would like his wall sections to be. Thought we'd leave that up to you -- there is a booster set of parapetted wall sections available separately to make the walls longer.
Usual great job by John Bear Ross and a very handsome paintup by the talented Martin of the blog Fire Broadside.
