My apologies if this counts as a double post. I have posted a thread of my new map without realizing that I should have posted it here to begin with. I would really love to see my map played at least once.
It's already updated for the Grocket and Uberupdate.
The grid_walls section is merely the skybox, and where people are sent after they fall into the pit. the melee_checkers portion of the map is full-size.
