A viral site for Metal Gear Rising: Revengence - waronourshores.com - does an amazing job of doing capturing the Metal Gear legacy bringing the game's plot into focus slightly, while confusing the hell out of people. (Or maybe just me.)
The recording is supposedly a private conversation from Colorado Senator Stephen Armstrong to a member of his staff. He talks about the Metal Gear series' greatest hits: role of media, using war to re-establish the greatness of America, a secret project called "desperado", and uses the phrase "Sons of Liberty".
If you were worried that Metal Gear Rising: Revengeance was going to become unrecognizable because of its new gameplay style and a new developer, well, let's just say it sounds like the apple hasn't fallen too far from the giant robot.
