In Silicon Knights’ 2002 Gamecube cult favorite, Eternal Darkness: Sanity’s Requiem, several voice actors from Metal Gear Solid can be heard. Voice talent including David Hayter (“Solid Snake”) and Paul Eiding (“Roy Campbell”) play various characters throughout the narrative ranging from NPCs to supporting cast.
In 2004, Silicon Knights and Konami released Metal Gear Solid: The Twin Snakes for the Gamecube, a remake of the PlayStation original that featured updated graphics and gameplay elements cherry picked from Metal Gear Solid 2.
The Twin Snakes utilized the entire English voice cast from the 1998 original at David Hayter’s suggestion.
