Encompasses: Every Default world, Mass Downloader
The Gauntlet is special because it’s sole purpose is to make it easier to download all of the default worlds. Every room in this world has a window to a different world, which forces your client to download it. Simply walk straight through, letting each one download. At the end, if you restart, all of the default worlds will be installed - you do not need to restart for each one you download.
Fortunetaly, this process is obsolete if you download the latest version of Worlds.
