gm_katurn is the first in a series of maps by Kat, probably. Based loosely around the layout of gm_squares, it features six platforms connected by bridges and surrounded by water, as well as a growing amount of buildings attached to a main wall splitting the entire map into two parts.

All screenshots by Kat, so the water looks icky D< If anyone has screenshots feel free to replace these :D
