Mmm, Skyscraper v1.0
This map appeared for a few versions in my Underworld map pack. However, I hardly hosted it, and never saw anyone else host it, so I decided to replace it in Underworld 1.4. I put so much work into this map that throwing it out would be a waste. It's still fun to play, and it's a good demonstration of multi-floor buildings in Marathon/Aleph One. Enjoy the map!
