So, I made a half flatgrass, have ocean map a little while ago, and let someone use it for their server. Well, now I'm seeing it pop up more often. So, I figured I might as well let anyone who feels like it go ahead and use it.
It's exactly like it sounds, one half of the map is flatgrass (with a bit of a bonus at the bottom), and then a single wall of adminium (sorry to copy that term, but really, I love it), then just a regular ocean. But, I forgot to add a surface to the bottom of the original ocean half of the map, so this one has a layer of sand at the bottom of the ocean for building convenience.
