I just checked it out on Major's Minute, and it's legit.
In the background, I can make out several occurrences of the words 'they are'. I can also see 'kiju', 'kujuu', 'thing'
In the bottom right corner (partly obscured by the Xbox logo), I believe I can see 'they are in Kijuju'.
A quick Google search tells me that Kijuju is the fictional part of Africa the game takes place in.
Any theories?
I think 'they' refers to either the BSAA (Chris and Sheva) or whoever it is they're looking for.
