Relic Castle

Hey there. I've got Essentials v16 with the BW stuff, and I have Battle Frontier scripts and PBS files but I'm not really sure what they do. Essentials Docs Wiki wasn't that much help since it just pointed me to an example map which I didn't have in my install. Can anyone explain what the Battle Frontier scripts do and how to deal with them, or recreate the example map in a form I can download and play with? Thanks in advance.
