The Metal Gear Solid series has always amused itself by ensuring that as little of the fourth wall exists as can be, while still insisting that the player take the game seriously. Usually, that would be a recipe for tragedy, but Metal Gear Solid is just so good that it just works - for the most part anyway.
Toward the end of Metal Gear Solid 2, things start falling apart a little bit. The Colonel starts speaking in non-sequiturs, the love story gets smothering (and then gets bizarre), and you learn that pretty much the entire game to this point has been, to a large extent, a lie. These plot twists are annoying, and haven't really aged well. What has aged just fine is the scene in the elevator chase in the Sigmoid Colon (?!) of Arsenal Gear. You get a sword (the coolest weapon in the game, and you get it for something like five minutes), you get Solid Snake as a wingman (infinite ammo, he helpfully reminds you shortly before), and about halfway through the wave, you get this screen.

Just don't get me started on the rest of the ending...
