For the purpose of this document, a glitch is any in-game phenomenon that is clearly not intended by the developers. Examples include skipping essential parts of the game and abnormal movement. All known glitches will be documented, even if they do not allow faster completion of the game.
On January 19th J-N found a new skip for Metal Gear Solid: The Twin Snakes. After having played around with it for a bit he found out that simply going quickly back over the hump of the vent when the camera makes you look down let's you completely skip the 1st Master Miller Codec Call savin a few seconds with 0 effort.

Shows how Snake moves out of the Nuke Building 1F back to the Canyon, but instead of loading into the level the game over screen appears.
