Duke Arena Beta Demo is for version 1.3. It has 5 new levels and the file is 1.7MB in size. The file name is darenabeta.zip. It was released on February 28, 2000.

Duke Arena Beta Demo is for Dukematch with or without bots, Capture The Flag and King Of The Hill only. It works with the original Duke levels plus the 5 new levels. There is new art and sounds plus ladders you can climb and a replacement machine gun. I tried Dukematch with bots and it was very hard because all the usual aliens were changed to bots.
