i sadly do not have an xbox but ps3 suits me just well, and i've tried a couple of these theories with my friends but they don't seem to work even though they are specifically detailed. There was one guy on this forum that i can't recall but he managed to crack the encoding to the map and found that spelling out "luna" in the sky was just like a certain key. and there were 2 other words that you could spell out of the sky that would lead you to a "secret1" or a "secret2" depending on what word you spelled. i believe one of these words was "hitsam" and the other "hyena". positive about first word, not sure about hyena but if someone could try spelling these to see if something different happens, cause what i found annoying was that everyone ignored this guy when it seemed plausible. so... just throwing that out there.
