Help us guess the game on the mystery memory stick

It's not uncommon to get sent game images and videos on a memory stick - but today we've recieved a memory stick which contains two very cryptic 'clues'. A weird audio file and a text doc. What can it all mean?

Is this a PR stunt for a big, unannounced game or is it a way of drummingup coverage for a lesser one? Help us work it out.

The text file reads like this (the first letters of each word spell CIPHER)

Cryptography

Isotope

Philanthropy

Hydrogen

Ember

Rebirth

The audio file is this:

Mystery audio file (00:01:15)

So then game detectives, what do you think? Is it to do with Splinter Cell? A new Bond game? Alpha Protocol? The Agency? Rockstar's Agent? Or are we barking up the wrong tree entirely?
