Metal Gear Solid: The Twin Snakes is an action-adventure stealth video game developed by Silicon Knights in conjunction with Konami as an exclusive for the Nintendo GameCube.  Published by Konami, Twin Snakes is a remake of the original Metal Gear Solid which released exclusively for the PlayStation in 1998.  The game features graphical improvements, new cutscenes written and directed by Japanese filmmaker Ryuhei Kitamura and gameplay functions originally introduced in the sequel Metal Gear Solid 2: Sons of Liberty.

The remake uses the same story and dialogues as the original 1998 PlayStation release however all voice acting was re-recorded due to audio quality issues of the original recordings.   The improved audio capability of the GameCube picked up outside noise from the original recordings that were inaudible on the PlayStation.   The new recordings were made using almost all the original English voice actors at the request of David Hayter, the voice of Solid Snake.   Hayter persuaded Konami to have the original voice cast reprise their role and only minor changes were made to the original performances.

Nintendo officially announced that the remake of the original Metal Gear Solid was in development for the GameCube on May 1, 2003 and that development was being led by Silicon Knights as the Konami team was busy developing Metal Gear Solid 3: Snake Eater.   Denis Dyack, president of Silicon Knight was appointed director of the game with Hideo Kojima and Shigeru Miyamoto overseeing development.  A playable demo of the game was available at E3 2003 which revealed that the game would feature the same style of gameplay as Metal Gear Solid 2 such as first-person aiming and being able to move bodies around.
