This is my second map, again its a tiny one, but i think you will enjoy it. I got the idea after i saw a download for a map that had just shotguns, but the link was broken, so i decided to make my own. Its a map with 4 hallways that lead into a central arena. The reason its for opposing forces is because it has the knife in it, and i thought with lack of maps for op4, this would make a nice addition.
