This is an earlier version of the map best known as Stadium '01 by Tracer - I wouldn't usually bother to give it its own screenshot page, but since Tmon & Tux do offer it for download, it seems only polite to include it here too.  I don't think you need both versions, however, and the later map has many improvements, so this is really only one for people who have lots of spare space on their hard drives!
