Looks good!
I have a question regarding the terrain mat with the wrecked submersible. It comes in 24" x 24" or 36" x 36" sizes. Does the larger size have more sea floor around the edge, with the interior plan remaining the same size? Or is the submersible interior enlarged as well?
I am trying to estimate the sizes of the chambers based upon the image.
The 36"x36" mat has a slightly larger sub but overall it is only about 10% bigger. For the most part, the sub is meant to be a certain size. In the 24"x24" map, the exit chamber, for example, is around 6" x 4". Doorways are about 1.5" across.
That being said, I can customize a map with a sub of whatever size you want for the 36x36 map.
