@TimSweeneyEpic Question, there is a supposedly secret map in Unreal 1/Unreal Gold which can be entered by typing disconnect in main menu. Was it's purpose to be loaded as a anti-piracy measure? Since the map takes place in a prison which you can't escape nor leave the map.
Yes. It existed because my early engine code didn’t support not having some level loaded. I think somebody chose that as a joke analogy to the Web’s 404 Not Found error screen.
