I know the contest starts July 1st, I just went through a few map concepts, doodling in radiant and came up with this. I will not be working on this til July 1st as I am still exhausting myself trying to get Base Ball Field II out. Well anyways here's the first look.
Added more structure
Added 2 crossing ziplines
Added Scuba Zombies
if you have any suggestions on how to make this map more fun please comment!
