Jedi Knight II: Jedi Outcast Easter Egg - Jk2 Secret Room possibly a code ??

First get the the main menu in single player, then open up your console by hitting shift and ~ at the same time. Then in the console type devmapall doom_comm then hit enter; once you're there type devmapall and hit enter again. Then in console type noclip (a cheat that allows you to get anyone through anything) and hit enter. Once you're in noclip mode jump up right out of the hyper space bubble thingy. When you're up there you will see a picture of Earth blowing up. Slightly under it is a room/box. Go inside the room and look around; there will be one wall that has a weird code on it I dont know what it means.
