Text strings I grabbed just by using Notepad++ on some of the game files from EoN and its two demos. It's a lot that I'm not too interested in really describing so hope that TCRF gets on that ball one day.
A few things I can say at least are...
1. Ground Zero,
Underworld, Everything or Nothing, and all the post-game stuff
were not originally in the game before its three month delay.
2. MI6
Interludes and secondary sections to some levels mostly have names. Le Rouge's
section is called Ashes to Ashes, Jaws' section in
Dangerous Descent is Dead Drop, and the VTOL boss in
The Final Card is Everything or Nothing. The first MI6 Interlude
is A Warm Reception, the second MI6 Interlude is A Quick Stop,
the second M meeting is Small Secrets, the first Q-Lab visit is
New Toys, the third Q-Lab visit One Last Thing.
3. Single
Player was also meant to have a chapter system akin to Co-Op. It would've been
Egypt, Peru, New Orleans, The Bayou,
Peruvian Return, and Moscow.
