Giant Bomb Mailbag: Numbers Station Edition

A nondescript manilla envelope showed up at the Giant Bomb offices this morning, and since its recipient wasn't here to open it, I took it upon myself (sorry Brad!) to rip into it, only to discover a mystery within! A mystery that neither Vinny or I were able to make any immediate sense of, which is why we now bring it to you, the infinitely smarter Giant Bomb audience.

Inside the envelope, which featured no return address, was an unmarked 1GB USB drive, which itself contained just two files: a 4KB README.txt file, along with a 1.5MB station.mp3 file. I've quoted the contents of the README file below, and you can listen to the MP3--which seems pretty clearly patterned after numbers stations--here.

Cryptography


Isotope


Philanthropy


Hydrogen


Ember


Rebirth      

Additionally, we found the following text code embedded in the MP3 file.

00000000 00000210 00000825 000000000037474B 00000000 0016FDA0 00000000 00000000 00000000 00000000 00000000 00000000    

Through a little audio editing snoopery, Vinny figured out that the backwards voice near the end of the MP3 file is saying "Don't believe everything you see." Aside from this clue, and the fact that the words in the README file make the obvious acronym CIPHER, I can't make much sense of this. It seems pretty clear to me that this is the first step in some kind of game-promoting ARG, but the question remains, what game could it be for? The fact that the voice reads the letters "NOD" might suggest some sort of Command & Conquer connection, though with C&C4 already out, it seems like an unlikely candidate. The only other game that jumps out at me as a possible connection is Fallout: New Vegas, mostly because of the nature of the vocabulary featured in the README file.
 
I imagine this same package is showing up at other game publications today as well, so let's see if we can't be the first ones to crack it wide open! Get to it in the comments below! 
 
UPDATE: It would seem that with some simple character shifting, folks were able to figure out that the letters and numbers being read decoded into a website address, www.gknova6.com. This is just the second step in the puzzle, though, as there's more numbers station fun to be had there. Keep it going, folks! 
 
UPDATE #2: The goodly folks at Joystiq have taken this the rest of the way, and though there's still no official confirmation, the signs seem to point very directly towards Fallout: New Vegas. Thanks for playing!
