well if you are the host server you can enable the cheats yourself.
in the console (shift+~) type 'devmap <map_name>' that will reload the map with all the cheats enabled. after that, just holster your saber[which means stop using it] and open the console again and type /thedestroyer.
now '/thedestroyer' doesnt work foreverone, sometimes its \ instead of /, and sometimes its capitalized instead of lowercase. fool around with it, and you will figure it out.
