Subsistence was released in Japan on December 22, 2005, later in North America on March 14, 2006, in Europe on October 6, 2006 and in Australia on October 13, 2006. Metal Gear Solid 3: Subsistence continues the Metal Gear Solid series tradition of follow-up enhanced, international version releases.

While previous releases, such as Metal Gear Solid: Integral and Metal Gear Solid 2: Substance included skill challenge missions and/or side story missions, Subsistence eschews the extra single-player missions to include updated versions of the series' first two games. Subsistence's online multiplayer component, titled Metal Gear Online, is comprised of five tournament-style game modes, each with a capacity of up to eight players.
