"Big, slow-moving elevators" is a network level that can be played alone so you fight the aliens or you can play network without the aliens. (You can do this by hitting the "are monsters / aren't monsters" toggle switch in the "gather network game" parameters box.)
If you've played my other network levels ("Bug Jar" - with all the troopers, and "Heehhaaa!" - the Jharo texture "bunker" level) and enjoyed them, you'll be happy you downloaded this hairpuller. Remember, the only shield cannisters are in the dark hallways down in the basement...
There is no hill (the center of the map being an elevator) and no ball. If you want to modify it to make it harder or easier, just open the map in forge after demerging with the "marathon map-splitter".
