The Document of Metal Gear Solid 2 is an interactive "making of" documentary released for the PlayStation 2 on September 12, 2002 in Japan and September 24 of the same year in North America. It allows the player to view all of the polygonal models used for characters, mechanics and areas in the game and listen to the game's soundtrack.
The disc also features all of the real time cut-scenes from the game with the audio removed and their respective storyboards, allowing the player to actively explore them and control them. Other features include special behind-the-scenes footage, all of the game's pre-release trailers, the completed script, Hideo Kojima's original game plan (available only in Japanese), the chronicle of MGS2, and a gallery of Metal Gear Solid related products and merchandise.
The disc also includes five "VR Training" levels that served as a precursor to Metal Gear Solid 2: Substance.
Although it did not receive a standalone European release, the disc was packaged in the PAL PlayStation 2 version of Metal Gear Solid 2: Substance for no extra charge, to compensate for both games' late releases. It was also included in the 20th Anniversary Edition re-release of the original Metal Gear Solid 2 in Japan.
