With any luck, the next set of tiles for the Colony 19 range should be out by the end of the week (thanks to several days of working on them non-stop).
In the meantime, I thought I would post a quick picture of how one of the new (larger) rooms fits together with some of the tiles from the starter set:
(note that the white rectangles = doors)
...there's also a few more 'dressing' pieces shown, as well as a couple of narrow (maintenance) tunnels to add a bit of variety.
Like before the pdf will contain nine pages of tiles (one of which will probably consist entirely of doors this time around), and be available for a similar price.
