KotH Skybox is a small map where everything is rendered in the 3D skybox, allowing you to see everyone and everything at all times. This map does not work if you have r_3dsky 0.
I made this map back in 2013 for April Fools. Maps were submitted in secret, and I never followed up with a map thread because I didn't think much of it. That was a mistake, because apparently this map was good enough for someone else to claim as their own, so I'm publishing it myself.
